Opis:
ACL rupture is a common injury in professional sport as well as recreation. It happens most often during deceleration, lateral pivoting, or landing tasks. Most often it is a non-contact mechanism during which the knee is exposed to large forces. The main component of the ACL, reaching 75% of the content, is collagen. Ligaments are made of several types of collagen, which perform different functions. It has been proved that various variants of collagen genes and their interaction with other genes may significantly influence the risk of injury to the ACL. This publication contains a review of studies about polymorphisms of collagen genes in the context of ACL rupture.

Opis:
Colorectal cancer (CRC) is one of the deadliest cancers which lie in the incidence of morbidity in second place. Intensive research is to determine and confirm the genetic basis of this disease, which is believed may have a direct relationship with the reduced efficiency of DNA repair systems. The aim of this study was to determine the effect of APEX gene polymorphism Ile64Val on increasing the risk of colorectal cancer in the Polish population. Material and methods. The blood samples collected from 150 patients diagnosed with colon cancer was used. The control group consisted of 150 healthy subjects. Genotyping was performed by TaqMan method. Results. The results indicate that genotype Ile Val is associated with an increased risk of colorectal cancer (OR 2.069; 95% CI 1,205-3,552; p = 0.008). Conclusions. Based on these results, we conclude that the APEX gene polymorphism Ile64Val may be associated with an increased risk of colorectal cancer.

Opis:
Heme oxygenase-1 (HO-1) is an enzyme which catalyzes the rate-limiting step in heme degradation resulting in the formation of iron, carbon monoxide and biliverdin, which is subsequently converted to bilirubin by biliverdin reductase. The biological effects exerted by the products of this enzymatic reaction have gained much attention. The anti-oxidant, anti-inflammatory and cytoprotective functions associated with HO-1 are attributable to one or more of its degradation products. Induction of HO-1 occurs as an adaptive and beneficial response to several injurious stimuli including heme and this inducible nature of HO-1 signifies its importance in several pathophysiological disease states. The beneficial role of HO-1 has been implicated in several clinically relevant disease states involving multiple organ systems as well as significant biological processes such as ischemia-reperfusion injury, inflammation/immune dysfunction and transplantation. HO-1 has thus emerged as a key target molecule with therapeutic implications.

Opis:
Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by restriction enzymes. RFLP-PCR is an easy-to-perform and inexpensive tool for initial analysis of SNPs potentially associated with some monogenic diseases, as well as in genotyping, genetic mapping, lineage screening, forensics and ancient DNA analysis. The RFLP-PCR method employs four steps: (1) isolation of genetic material and PCR; (2) restriction digestion of amplicons; (3) electrophoresis of digested fragments; and (4) visualisation. Despite its obsolescence and the presence of high-throughput DNA analysis techniques, it is still applied in the analysis of SNPs associated with disease entities and in the analysis of genetic variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). RFLP-PCR is a low-cost and low-throughput research method allowing for the analysis of SNPs in the absence of specialised equipment, and it is useful when there is a limited budget.

Opis:
Steroid therapy, due to a wide range of anti-inflammatory properties of steroids, is a basic field of treatment in many human diseases including the nephrotic syndrome in children. However, not all patients respond positively to therapy which divides them into steroid sensitive (SS) and steroid resistance (SR) individuals. Many potential factors associated with steroid resistance have been identified so far. It seems that genetic factors associated with glucocorticoid receptor α (GRα), the structure of heterocomplex of GR as well as glycoprotein P or cytochrome P450 may play a role in the induction of glucocorticoid resistance. Here we described several of the molecular mechanisms, which can regulate glucocorticoid sensitivity and resistance. Moreover, we presented genetic defects, which can lead to various effects of treatment and, in a longer perspective, enable clinicians to individualize therapies.

Opis:
Graves' (GD) hyperthyroidism induces accelerated bone turnover that leads to decreased bone mineral density (BMD). The role of the VDR gene in predisposition to primary osteoporosis has been recognized. Recent studies show associations between the VDR gene polymorphisms and susceptibility to autoimmune diseases. Here we analyzed if VDR gene polymorphisms: BsmI, ApaI, TaqI, and FokI may predispose women with Graves' hyperthyroidism to BMD reduction or to disease development. The subjects were 75 premenopausal female Polish patients with GD and 163 healthy women. The genotyping was performed by the use of the restriction fragment length polymorphism analysis (RFLP). We studied the association of the VDR polymorphisms and their haplotypes with patients' BMD and also SNPs and haplotypes association with Graves' disease. We found a strong linkage disequilibrium for the BsmI, ApaI, and TaqI polymorphims that formed three most frequent haplotypes in Graves' women: baT (47.9%), BAt (34.9%), and bAT (16.4%). We did not show statistically significant association of analyzed VDR polymorphisms or haplotypes with decreased bone mineral density in Graves' patients. However, the presence of F allele had a weak tendency to be associated with Graves' disease (with OR=1.93; 95% CI: 0.97-3.84; p=0.058). In conclusion: VDR gene polymorphisms do not predict the risk of decreased BMD in Polish women with Graves'. It may be speculated that the F allele carriers of the VDR-FokI polymorphism are predisposed to Graves' disease development.

Opis:
The incidence of colorectal cancer (CRC) is increasing from year to year. Despite intensive research CRC etiology remains unknown. Studies suggest that at the basis of the process of carcinogenesis can lie reduced efficiency of DNA repair mechanisms, often caused by polymorphisms in DNA repair genes. The aim of the study was to determine the relationship between gene polymorphism Lys589Glu of EXO1 gene and modulation of the risk of colorectal cancer in the Polish population. Determination of the molecular basis of carcinogenesis process and predicting increased risk will allow qualifying patients to increased risk group and including them in preventive program. Material and methods. The material used in study was blood collected from 130 patients diagnosed with colorectal cancer. The control group consisted of 135 healthy people. Genotyping was performed by TaqMan method. Results. The results obtained indicate that the genotype Lys/Glu is associated with an increased risk of colorectal cancer (OR 1.811, 95% Cl 1.031-3.181, p = 0.038). Conclusion. On the basis of these results, we conclude that Exo1 gene polymorphism Lys589Glu may be associated with an increased risk of colorectal cancer.

Opis:
Folic acid is an important vitamin in human nutrition and its deficiency in pregnant women's diets results in neural tube defects and other neurological damage to the fetus. Additionally, DNA synthesis, cell division and intestinal absorption are inhibited in case of adults. Since this discovery, governments and health organizations worldwide have made recommendations concerning folic acid supplementation of food for women planning to become pregnant. In many countries this has led to the introduction of fortifications, where synthetic folic acid is added to flour. It is known that Saccharomyces strains (brewing and bakers' yeast) are one of the main producers of folic acid and they can be used as a natural source of this vitamin. Proper selection of the most efficient strains may enhance the folate content in bread, fermented vegetables, dairy products and beer by 100% and may be used in the food industry. The objective of this study was to select the optimal producing yeast strain by determining the differences in nucleotide sequences in the FOL2, FOL3 and DFR1 genes of folic acid biosynthesis pathway. The Multitemperature Single Strand Conformation Polymorphism (MSSCP) method and further nucleotide sequencing for selected strains were applied to indicate SNPs in selected gene fragments. The RT qPCR technique was also applied to examine relative expression of the FOL3 gene. Furthermore, this is the first time ever that industrial yeast strains were analysed regarding genes of the folic acid biosynthesis pathway. It was observed that a correlation exists between the folic acid amount produced by industrial yeast strains and changes in the nucleotide sequence of adequate genes. The most significant changes occur in the DFR1 gene, mostly in the first part, which causes major protein structure modifications in KKP 232, KKP 222 and KKP 277 strains. Our study shows that the large amount of SNP contributes to impairment of the selected enzymes and S. cerevisiae and S. pastorianus produce reduced amounts of the investigated metabolite. The results obtained here yield a list of genetically stable yeast strains which can be implemented as a starter culture in the food industry.

Nine SNPs spanning the HNF4 alpha P2 promoter (rs4810424, rs1884613 and rs1884614) and coding region (rs2144908, rs6031551, rs6031552, rs1885088, rs1028583 and rs3818247) were genotyped in 160 subjects without diabetes or metabolic syndrome. The HNF4 alpha P2 promoter SNPs rs4810424, rs1884613 and rs1884614 were associated with insulin resistance (p = 0.017; 0.037; 0.024) and body mass index (BMI) (p = 0.03; 0.035; 0.039). The intron 1D SNP rs2144908 was associated with high-density lipoprotein cholesterol (HDLc) (p = 0.020) and the intron 9 SNP rs3818247 showed association with systolic (p = 0.02) and diastolic (p = 0.034) blood pressure. HNF4 alpha common haplotype CCCGTC associated with higher insulin resistance (p = 0.022), fasting blood glucose (FBG) (p = 0.035) and lower HDLc (p = 0.001). In conclusion, subjects with HNF4 alpha P2 variants and haplotypes have been shown to have a higher insulin resistance and are therefore at a higher risk for developing type 2 diabetes mellitus.

The aim of our study was to investigate the dependence of the aerobic capacity parameters in sport on the set of gene polymorphisms. Cardio-respiratory system (CRS) adaptation reactions to exercise of 72 endurance athletes were assessed using the gas analysis. The analysis of the obtained results has shown both single and combined effect of the gene polymorphisms on the aerobic capacity. The impact of 6 polymorphisms on the aerobic performance level was analyzed: Т–786→С polymorphism of the promoter of еNOS gene as well as АСЕ I/D polymorphism, Рго/Ala polymorphism of PPARG gene, G/C polymorphism of PPARA gene, Pro582Ser polymorphism of HIF1α gene, and Ala203Pro polymorphism of PPARGC1B. It was found that a single impact on the HRmax providing АСЕ I/D polymorphism. Individual influence of АСЕ gene accounts for 2% of this index dissipation. Results showed that there is a dependence between the amount the maximum volume of consumed oxygen (VO2max) from the set of gene polymorphisms. Cumulative impact of these polymorphisms in the combination with the individual parameters (gender; qualification; kind of sport) stipulates 71% of dispersion of VO2max value.

Opis:
Introduction and aim. Inguinal hernias are one of the major disorders in the field of general and visceral surgery and can be viewed as multifactorial diseases. Although the molecular mechanism that led to predistortion to inguinal herniation still remain unclear, is well known that defects leading to improper closure of the inguinal canal during fetal development and mechanisms contributing to weaker muscles of the abdominal wall can greatly increase the risk of developing the latter disease. Material and methods. A literature search was performed in all major electronic databases using keywords and Boolean operators to retrieve all available literature related to the topic. Due to the narrative nature of the review, there were no specific inclusion and exclusion criteria. Analysis of the literature. Genetic factors, undoubtedly, can interfere with these mechanisms and therefore play major role in developing hernias. To this end, the present narrative review provides an overview of genes with altered expression and genetic polymorphisms associated with inguinal herniation. Moreover, the results of genome-wide association studies (GWAS) exploring susceptible genetic loci associated with the disease have been reported. Conclusion. Nevertheless, more case-control studies and GWAS need to be conducted in different ethnic populations so as to provide better insights into the topic.

Changes in CDKN2a gene are known to be linked with sporadic melanoma and hereditary predisposition to this cancer. In the Polish population mutations in the coding region of the CDKN2a gene are rather rare, therefore the attention has been focused on polymorphisms and alterations in uncoding regions such as 3' UTR. The aim of this study was to analyze two common polymorphisms, Ala148Thr and 500 C/G, and correlate them with the clinical course of melanoma. DNA from 285 patients was analyzed and found polymorphisms were correlated with the clinical parameters employing statistical methods. The obtained results allow us to conclude: (i) survival times of 500 C/G carriers vs. cumulating proportion surviving was not statistically significant; (ii) CDKN2a polymorphism 500 C/G correlated with Ala148Thr; (iii) no correlation was observed between the 500 C/G polymorphism and age of diagnosis, localization of primary melanoma and survival time; (iv) we did not find correlation between 500 C/G and type of cancer in the family; (v) changes in the CDKN2a gene were not found in patients with second cancer.

AIM The primary objective of the study, which is the basis of this thesis, was to evaluate the potential association between selected apM1 polymorphisms and the plasmatic concentrations of adiponectin and the incidence of overweight and obesity in the population of patients visiting general outpatient clinics of primary medical care. MATERIAL AND METHODS The reported study comprised a total of 510 adult patients (287 men and 223 women) from the region of southern Poland, who had subsequently sought medical counselling at a general outpatient clinic of primary care. The examined subjects were divided into three (3) groups, following waist circumference values. The control group consisted of patients with a waist circumference <94 cm for men and <80 cm for women. All the subjects had fasting serum concentrations of glucose, insulin, total cholesterol, HDL/LDL fractions, triglycerides, creatinine and adiponectin and genotyping of Y111H (rs17366743), +45 T>G (rs2241766) and +276 G>T (rs1501299) polymorphisms of the adiponectin gene. RESULTS The serum glucose and insulin concentrations in the overweight and obese subjects were statistically signifi cantly higher vs. those in the control group (p < 0.001). The serum adiponectin concentrations in the obese patients were signifi cantly lower vs. those in the overweight subjects (p < 0.001) or those without any excess weight (p < 0.001). Signifi cantly higher values of the HOMA-IR factor were found in both the obese and the overweight patients (p for correlation between either group < 0.01). A strong correlation was observed between the waist circumference and adiponectin levels. It was demonstrated that the adiponectin concentration in the blood decreased with a waist circumference increase (p < 0.001). A similarly strong correlation was noted between the adiponectin levels and BMI (body mass index) values (p < 0.001). The MAF values for the Y111H, +45 T/G and +276 G/T polymorphisms were 0.017, 0.098 and 0.287, respectively. No statistically signifi cant diff erences were demonstrated in the distribution of genotypes between the studied groups for the apM1 Y111H (chi2 = 2.61; p = 0.2706), apM1 +45 T/G (chi2 = 2.10; p = 0.7179) and apM1 +276 G/T (chi2 = 7.93; p = 0.0941) polymorphisms. However, statistically signifi cant diff erences were visualised in the distribution of alleles for the apM1 +276 G/T (chi2 = 6.10; p < 0.05) polymorphism. CONCLUSIONS The results of the reported study confi rm the existence of a strong, negative correlation between the adiponectin levels in the blood and waist circumference or BMI values, also described in a number of literature reports. 2. The apM1 Y111H, +45 T/G and +276 G/T polymorphisms, and in particular the fi rst one, are very rarely found in the Polish population. 3. No correlation was demonstrated between the studied polymorphisms and the incidence of overweight and obesity and serum adiponectin concentration. 4. In the population of subjects with an average GFR = 81.53 ml/min/1.73 m2, the adiponectin concentration positively correlates with glomerular fi ltration values.
CEL PRACY Głównym celem niniejszej pracy była ocena potencjalnego związku między wybranymi polimorfizmami genu apM1 oraz osoczowym stężeniem adiponektyny a występowaniem nadwagi i otyłości w populacji pacjentów zgłaszających się do poradni ogólnej podstawowej opieki zdrowotnej (POZ). MATERIAŁ I METODY Badaniem objęto łącznie 510 dorosłych pacjentów (287 mężczyzn i 223 kobiety) z rejonu Polski Południowej, którzy kolejno zgłaszali się do poradni ogólnej POZ. Badanych podzielono na 3 grupy, zależnie od wartości obwodu pasa. Grupę kontrolną stanowili pacjenci z obwodem talii < 94 cm (mężczyźni) oraz < 80 cm (kobiety). U wszystkich osób oznaczano na czczo w surowicy stężenia glukozy, insuliny, cholesterolu całkowitego, frakcji HDL i LDL, triglicerydów, kreatyniny oraz adiponektyny oraz określono polimorfizmy Y111H (rs17366743), +45 T > G (rs2241766) oraz +276 G > T (rs1501299) genu adiponektyny. WYNIKI W surowicy osób z nadwagą i otyłych stwierdzono istotnie statystycznie wyższe stężenia glukozy i insuliny w stosunku do osób z grupy kontrolnej (p < 0,001). Stężenia adiponektyny w surowicy pacjentów otyłych były istotnie niższe niż u osób z nadwagą (p < 0,001) oraz bez nadwagi (p < 0,001). Zarówno u osób otyłych, jak i z nadwagą stwierdzono znamiennie wyższe wartości wskaźnika insulinooporności HOMA-IR (p dla korelacji pomiędzy każdą z grup < 0,01). Wykazano, że stężenie adiponektyny we krwi maleje wraz ze wzrostem obwodu talii (p < 0,001). Podobnie silną korelację odnotowano między poziomem adiponektyny a wartościami wskaźnika BMI (p < 0,001). Wartości MAF dla polimorfizmów Y111H, +45 T/G oraz +276 G/T wynosiły odpowiednio: 0,017, 0,098 oraz 0,287. Nie wykazano istotnych statystycznie różnic w rozkładzie badanych genotypów między badanymi grupami dla polimorfizmu apM1 Y111H (chi2 = 2,61; p = 0,2706), apM1 +45 T/G (chi2 = 2,10; p = 0,7179) oraz apM1 +276 G/T (chi2 = 7,93; p = 0,0941). Uwidoczniono jednak istotne statystycznie różnice w rozkładzie alleli dla polimorfizmu apM1 +276 G/T (chi2 = 6,10; p < 0,05). Rozkład alleli i genotypów dla polimorfizmów Y111H oraz +45 T/G nie pozwalał na przeprowadzenie wiarygodnych analiz statystycznych. WNIOSKI 1. U badanych z nadwagą i otyłością występuje ujemna korelacja między obwodem talii a stężeniem adiponektyny. 2. Wykazano jednak istotne statystycznie różnice w rozkładzie alleli dla polimorfizmu apM1 +276 G/T pomiędzy badanymi grupami. 3. Nie wykazano zależności pomiędzy występowaniem poszczególnych polimorfizmów a stężeniem adiponektyny w surowicy. 4. Stężenie adiponektyny we krwi koreluje ujemnie z insulinemią i insulinoopornością oraz dodatnio z wielkością filtracji kłębuszkowej.

Opis:
Local adaptation is a key concept in biology: shift of genetic structures of populations due to differential survival of genotypes is expected to lead to phenotypes providing an advantage in the local environment. Variation of sequences of twelve candidate genes was investigated in 13 Norway spruce (Picea abies (L.) Karst.) provenances originating from sites distributed along an altitudinal gradient from 550 to 1300 m a.s.l. Signals of selection were assessed in 103 single nucleotide polymorphisms (SNP). The Bayesian FST-outlier identification methods as implemented in the programs BayeScan and Arlequin did not identify any SNP with a clear evidence of selection. The approaches relying on SNP-climate associations (spatial analysis method based on logistic regression of allele frequencies with environmental variables, Bayesian method applied in BayEnv2) identified several relationships but none of them remained significant after correction for multiple testing. Gene flow, epigenetic inheritance and former management of the studied populations are discussed as potential reasons for this weak evidence of selec- tion signals.

Opis:
SNP sites are generally discovered by sequencing regions of the human genome in a limited number of individuals. This may leave SNP sites present in the region, but containing rare mutant nucleotides, undetected. Consequently, estimates of nucleotide diversity obtained from assays of detected SNP sites are biased. In this research we present a statistical model of the SNP discovery process, which is used to evaluate the extent of this bias. This model involves the symmetric Beta distribution of variant frequencies at SNP sites, with an additional probability that there is no SNP at any given site. Under this model of allele frequency distributions at SNP sites, we show that nucleotide diversity is always underestimated. However, the extent of bias does not seem to exceed 10-15% for the analyzed data. We find that our model of allele frequency distributions at SNP sites is consistent with SNP statistics derived based on new SNP data at ATM, BLM, RQL and WRN gene regions. The application of the theory to these new SNP data as well as to the literature data at the LPL gene region indicates that in spite of ascertainment biases, the observed differences of nucleotide diversity across these gene regions are real. This provides interesting evidence concerning the heterogeneity of the rates of nucleotide substitution across the genome.

Opis:
Graves' (GD) hyperthyroidism leads to reduced bone mineral density (BMD) accompanied by accelerated bone turnover. Ample studies have identified association between estrogen receptor (ESR1) gene polymorphism and decreased BMD and osteoporosis. In contrast, number of publications that link ESR1, BMD and Graves' disease is limited. The purpose of this study was to identify the association between ESR1 polymorphisms and BMD in premenopausal women with GD and to determine whether ESR1 polymorphic variants can predispose to GD. The study included 75 women aged 23-46 years with GD and 163 healthy controls. BMD was measured at lumbar spine and femoral neck. We investigated two SNPs in the ESR1 gene and analyzed genetic variants in the form of haplotypes reconstructed by statistical method. Three out of four possible haplotypes of the PvuII and XbaI restriction fragment length polymorphisms were found in GD patients: px (55.3 %), PX (33.3 %) and Px (11.4 %). Women homozygous for xx of XbaI and for pp of PvuII had the lowest BMD at lumbar spine. Moreover, the px haplotype predisposed to reduced lumbar BMD. No associations were observed for femoral neck BMD. No statistically significant relationship were found between ESR1 polymorphisms or their haplotypes and GD. These results indicate that the PvuII and the XbaI polymorphisms of ESR1 gene are associated with bone mineral density in premenopausal women with GD and may help to estimate the risk of bone loss particularly at lumbar spine. However, none of the ESR1 gene alleles predict the risk of GD in Polish female patients.

Here, we have developed a highly sensitive, real-time allelic discrimination assay enabling detection of the Y831C mutation in the POLG1 gene. The Y831C mutation is present in the Polish population at a frequency of 2.25%. The new assay is well suited to both extensive population studies and molecular diagnostics of POLG1.

WSTĘP: Wśród najczęstszych przyczyn nadwagi i otyłości brzusznej wymienia się czynniki środowiskowe oraz genetyczne. Wśród czynników genetycznych biorących udział w patogenezie otyłości brzusznej w różnych popula-cjach opisywano wiele polimorfizmów genów, w tym polimorfizmy genu receptora witaminy D (VDR). CEL: Celem przeprowadzonego badania było znalezienie zależności pomiędzy wybranymi polimorfizmami genu VDR [rs731236, rs1544410 i rs7975232] a występowaniem nadwagi i otyłości brzusznej wśród kolejnych osób zgłaszających się do zakładu podstawowej opieki zdrowotnej. MATERIAŁ I METODY: Badaniem objęto 495 kolejnych pacjentów. U badanych określono występujące zaburzenia gospodarki lipidowej, węglowodanowej oraz ciśnienia tętniczego, a także polimorfizmy genu VDR [rs731236, rs1544410 i rs7975232]. WYNIKI: Po przeprowadzeniu badania stwierdzono: 1) u > 60% osób, kolejno zgłaszających się do lekarza POZ, stwierdza się nadwagę lub otyłość; 2) nadwadzie i otyłości brzusznej towarzyszą rozwijające się zaburzenia metaboliczne; 3) u badanych brak znamiennych statystycznie zależności pomiędzy badanymi polimorfizmami VDR a obec-nością nadwagi i otyłości brzusznej; 4) znamienna statystycznie zależność pomiędzy obecnością allelu G polimor-fizmu rs731236 genu VDR a nadwagą/otyłością brzuszną sugerować może znaczenie tego polimorfizmu w patoge-nezie nadwagi/otyłości brzusznej. WNIOSKI: Znaczenie badanych polimorfizmów genu VDR [rs731236, rs1544410 i rs7975232] w patogenezie rozwoju nadwagi/otyłości brzusznej w badanej przez nas grupie osób jest niewielkie. Podobnie jak niewielkie znaczenie wydaje się mieć obecność allelu G polimorfizmu rs731236 genu VDR w patogenezie nadwagi/otyłości brzusznej.
INTRODUCTION: Among the most common causes of overweight and abdominal abdominal obesity, environmental factors and genetic factors are mentioned. The role of the genetic factors involved in the pathogenesis of abdominal obesity have been described in different populations. Among the many gene polymorphisms, one should consider vitamin D receptor gene polymorphisms (VDR). AIM: The aim of the study was to find the relationship between the selected VDR gene polymorphisms [rs731236, rs1544410 and rs7975232], and the prevalence of overweight and abdominal obesity among consecutive patients visiting a primary care unit. MATERIAL AND METHODS: The study involved 495 consecutive patients. In the experiment group, lipid metabolism and carbohydrate metabolism disorders as well as blood pressure, and the VDR gene polymorphisms [rs731236, rs1544410 and rs7975232] were identified. RESULTS: After the study we drew up the following summary: 1) > 60% of people visiting a primary care unit are overweight or obese; 2) in subjects overweight and with abdominal obesity, metabolic disturbances were observed; 3) there was no statistically significant relationship between the VDR polymorphisms studied and the presence of overweight and abdominal obesity; 4) a statistically significant relationship between the presence of the G allele polymorphism rs731236 VDR gene and. overweight/abdominal obesity may suggest the role of this polymorphism in the pathogenesis of overweight/abdominal obesity. CONCLUSIONS: The importance of the studied VDR gene polymorphisms [rs731236, rs1544410 and rs7975232] in the pathogenesis of the development of overweight/ abdominal obesity in the study group is small. The presence of the G allele polymorphism rs731236 VDR gene in the pathogenesis of overweight/obesity seems to have a little significance.

Opis:
Angiotensin I-converting enzyme (ACE), which plays an important role in blood pressure regulation, and methylenetetrahydrofolate reductase (MTHFR) involved in homocysteine metabolism belong to a large group of polypeptides which may be potential risk factors for atherosclerosis and coronary artery disease (CAD). To assess whether polymorphisms of the genes encoding these peptides are associated with CAD in Silesian we conducted a study among 68 individuals suffering from CAD (including 52 cases after myocardial infarction), 51 subjects with positive family history of CAD and 111 controls. We analysed the distribution of genotypes and allele frequencies of the insertion/deletion (I/D) polymorphism in the ACE gene using PCR amplification, and the C677→T polymorphism in the MTHFR gene using PCR-RFLP analysis. We found that D allele frequency was significantly higher in CAD patients (61%) than in controls (43%) (P = 0.001, OR = 2.06). The D allele carriers (DD + ID genotypes) were more frequent in the CAD patients (85%) compared to control group (65%) (P = 0.003, OR = 3.14), whereas the familial CAD risk group shows the highest frequency of the ID genotype (57% vs 43% in controls). In contrast, the MTHFR polymorphism does not seem to be associated with the disease. Our data indicate that in Silesian CAD patients the disease is strongly associated with carrier-state of the ACE D allele, but not with the C677→T transition in the MTHFR gene.

Opis:
Objectives Objectives: Cigarette smoking is the major risk factor of bladder cancer via exposure to chemical carcinogens. Nicotinamide adenine dinucleotide phosphate (NADP+): quinine oxidoreductase 1 (NQO1) and sulfotransferase 1A1 (SULT1A1) have been reported to involve in the metabolism of polycyclic aromatic hydrocarbons (PAHs) and aromatic amines. Therefore, the risk of bladder cancer (BC) may be influenced by polymorphisms in the genes that modulate metabolic detoxification in particular by interacting with cigarette smoking. Considering the limited power by the individual studies with a relatively small sample size, especially when analyzing the combined effect of polymorphisms in NQO1 and SULT1A1 genes and smoking, these 2 meta-analyses have aimed to clarify the combined effects of them on BC risk by integrating related studies. Material and Methods Two meta-analyses included 1341 cases and 1346 controls concerning NQO1 Pro187Ser and smoking, and 1921 cases and 1882 controls on SULT1A1 Arg213His and smoking were performed. Odds ratios (OR) and 95% confidence intervals (CI) were used for assessing the strength of the association. Results The result has demonstrated that smokers with NQO1 Pro/Ser or Ser/Ser genotypes have a prominent association with the risk of BC as compared with non-smokers with NQO1 Pro/Pro genotype, with OR equal to 3.71 (95% CI: 2.87–4.78, $ \text{p}_\text{heterogeneity} $ = 0.376). Besides, smokers carrying SULT1A1 Arg/Arg genotypes were observed to confer 2.38 fold increased risk of BC (95% CI: 1.44–3.93, $ \text{p}_\text{heterogeneity} $ = 0.001) when compared with non-smokers with SULT1A1 Arg/Arg or His/His genotypes. Conclusions These findings have suggested that the NQO1 Pro187Ser or SULT1A1 Arg213His polymorphism combination with smoking significantly confer susceptibility to BC.

Opis:
Introduction. Alzheimer’s disease (AD) is one of the most common neurodegenerative diseases, which is a serious health problem for societies that live longer. Spontaneous dominant mutations and polymorphisms of selected genes play an important role in development of AD. Aim. Several polymorphisms in selected genes strongly associated with development of Alzheimer’s disease were highlighted in this review: APOE, CYP46, APP, PSEN1, PSEN2, UBQLN1, BACE1, PRND, APBB2, TOMM 40. These gene polymorphisms have a significant role in the development of Alzheimer’s disease and they have potential to be biomarkers. Researchers combine efforts to find significant polymorphisms that would ensure that a person is predisposed to the occurrence of disease symptoms. This topic is often taken up by scientists seeking to develop effective genetic tests for diagnosing AD. Material and methods. Analysis of literature from web of knowledge: Web of Science (all database), NCBI and PubMed. Results. We reviewed the selected important genes and polymorphisms which are most often associated with development of AD. Conclusion. It should be noted that nowadays scientists strive not to focus on only one polymorphism in the gene but on several polymorphisms in different genes concomitantly and above all on interactions between them to the diagnosis of this disease. Only this approach to AD will contribute to the creation of appropriate identification methods. Moreover, we should use the new generation tools - the platform for collecting data and personalized medicine.

Two recent studies found that RBMS1 gene rs7593730 and BCAR1 gene rs7202877 are related to type 2 diabetes. However, the association of these loci with type 2 diabetes mellitus (T2DM) has not been examined in Chinese. We performed a replication study to investigate the association of the 2 susceptibility loci with T2DM in the Chinese population. We genotyped 1961 Chinese participants (991 with T2DM and 970 controls) for each of the 2 single nucleotide polymorphisms (SNPs) rs7593730 in RBMS1 and rs7202877 near BCAR1 using SNPscan and examined their association with T2DM using logistic regression analysis. We also analyzed the correlation of the SNP alleles and clinical phenotypes. In additive model, genotype association analysis of BCAR1 rs7202877 loci revealed that the homozygous of rs7202877 GG carriers had significantly decreased T2DM risk compared to homozygous carriers of TT (P=0.038, OR 0.44, 95% CI 0.20-0.96). In the recessive model, the GG genotype GG had significantly decreased T2DM risk compared to GT+TT (P=0.043, OR 0.67, 95% CI 0.46-0.99). Allele G was statistically significantly correlated with TC (mmol/L) (P=0.036) and LDL-C (mmol/L) (P=0.007). As for rs7593730, the carriers of CT and TT genotype had significantly decreased T2DM risk compared to the carriers of CC genotype (CT: CC P=0.038, OR 0.71, 95% CI 0.51-0.98; TT: CC P=0.010, OR 0.32, 95% CI 0.13-0.76). In a dominant model, TT+CT: CC (P=0.013, OR 0.673, 95% CI 0.49-0.92) and in a recessive model, TT: CT+CC (P=0.019, OR 0.59, 95% CI 0.39-0.92). The T allele carriers had significantly decreased T2DM risk compared to the carriers of C (P=0.002, OR 0.65, 95% CI 0.50-0.86). Allele T was statistically correlated with FINS (P=0.010). In conclusion, our study showed that RBMS1 gene rs7593730 and BCAR1 gene rs7202877 were significantly associated with type 2 diabetes in the Chinese population.

Opis:
INTRODUCTION: Chronic glomerulonephritis is one of the common causes of chronic kidney disease that can lead to end-stage renal failure and the need for renal replacement therapy. Understanding the aetiology of this disease and its risk factors can help develop new methods of early diagnosis and effective therapy. Uromodulin is a protein with a broad spectrum of activity, and is involved in the key pathways that regulate kidney homeostasis. AIM OF THE STUDY: The aim of the study was to analyse the relationship between three selected polymorphisms (rs13335818, rs4293393 and rs13333226) of the uromodulin gene (UMOD) and the risk of chronic kidney disease caused by chronic glomerulonephritis. MATERIAL AND METHODS: 113 patients with chronic glomerulonephritis and eGFR < 60 ml/min/1.73 m2 (experimental group) and 196 patients from the General Outpatient Clinic without a history of renal disease and eGFR > 60 ml/min/1.73 m2 (control group) were recruited for the study. The study protocol assumed a one-time blood collection for genetic testing and serum creatinine level determination. Genetic material was isolated from the peripheral blood lymphocytes of the subjects. Genotyping of the analysed polymorphisms was performed using TaqMan SNP Genotyping Assay kits. The results were processed with statistical methods using Statistica 10 and Microsoft Office Exel 2003 software, the Mann-Whitney U test and the χ2 test. Statistical significance was adopted at p < 0.05. RESULTS: No statistically significant differences in the distribution of genotypes between the experimental and control groups were found for any of the three analysed UMOD variants. CONCLUSIONS: UMOD polymorphisms rs13335818, rs4293393 and rs13333226 are not associated with the risk of chronic kidney disease caused by chronic glomerulonephritis.
WSTĘP: Przewlekłe kłębuszkowe zapalenie nerek jest jedną z częstych przyczyn przewlekłej choroby nerek mogącej prowadzić do ich schyłkowej niewydolności i konieczności stosowania terapii nerkozastępczej. Poznanie etiologii tej choroby oraz czynników ryzyka daje nadzieję na wdrożenie nowych metod wczesnej diagnostyki i skutecznej terapii. Uromodulina jest białkiem prezentującym szerokie spektrum działań, włączonym w kluczowe szlaki warunkujące homeostazę nerek. CEL PRACY: Celem pracy była ocena związku wybranych trzech polimorfizmów (rs13335818, rs4293393 i rs13333226) genu uromoduliny (UMOD) z występowaniem przewlekłej choroby nerek na tle przewlekłego kłębuszkowego zapalenia nerek. MATERIAŁ I METODY: Do badania zrekrutowano 113 chorych z przewlekłym kłębuszkowym zapaleniem nerek i eGFR < 60 ml/min/1,73 m2 (grupa badana) oraz 196 pacjentów Poradni Ogólnej POZ bez chorób układu moczowego w wywiadzie, z eGFR > 60 ml/min/1,73 m2 (grupa kontrolna). Protokół badania przewidywał jednorazowe pobranie krwi do wykonania badań genetycznych oraz w celu oznaczenia stężenia kreatyniny w surowicy. Materiał genetyczny wyizolowano z limfocytów krwi obwodowej badanych. Genotypowanie badanych polimorfizmów przeprowadzono z wykorzystaniem zestawów TaqMan SNP Genotyping Assay. Uzyskane wyniki opracowano statystycznie na podstawie programów Statistica 10 i Microsoft Office Exel 2003 z wykorzystaniem: testu Manna-Whitneya i testu χ2. Za granice istotności statystycznej przyjęto wartości p < 0,05. WYNIKI: W zakresie żadnego z trzech badanych polimorfizmów UMOD nie stwierdzono znamiennych statystycznie różnic w rozkładzie genotypów pomiędzy grupami badaną a kontrolną. WNIOSKI: Nie wykazano związku polimorfizmów rs13335818, rs4293393 i rs13333226 genu UMOD z występowaniem przewlekłej choroby nerek na tle przewlekłego kłębuszkowego zapalenia nerek.

Opis:
Previous studies in other countries have shown that single nucleotide polymorphisms (SNPs) in the growth arrest-specific gene 6 (Gas6; rs8191974) and adapter-related protein complex 3 subunit sigma-2 (Ap3s2; rs2028299) were associated with an increasedrisk for type 2 diabetes mellitus (T2DM). However, the association of these loci with T2DM has not been examined in Chinese populations. We performed a replication study to investigate the association of these susceptibility loci with T2DM in the Chinese population.We genotyped 1968 Chinese participants (996 with T2DM and 972controls) for rs8191974 in Gas6 and rs2028299 near Ap3s2, and examined their association with T2DM using a logistic regression analysis. We also analyzed the correlation of genotypes and clinical phenotypes. The distribution of the T allele of SNP rs8191974 in the Gas6 gene was significantly different between T2DM cases and controls when compared with the C allele (P<0.05, OR: 0.80, 95% CI: 0.69-0.94). The occurrence of the CT genotype and the dominant model was also significantly less frequent in the T2DM cases vs. controls when compared with the CC genotype (CT vs. CC: P<0.05, OR: 0.75, 95% CI:0.62-0.90; TT+CT vs. CC: P<0.05, OR:0.75, 95% CI:0.63-0.90). In SNP rs2028299, the allele C showed no statistically significant differencein distribution between the control and T2DM groups when compared with allele A. However, in male populations, the dominant model was statistically more frequent when compared with genotype AA (CC+CA vs. AA: P<0.05, OR:1.29, 95% CI:1.02-1.64), and in obesity-stratified analysis, we also observed a significant difference in the distribution of the dominant model between the T2DM cases and controls in subjects with BMI≥24 kg/m2 and BMI<28kg/m2 (CC+CA vs. AA: P<0.05, OR: 6.33, 95% CI:4.17-9.61). In conclusion, our study shows that SNPsrs8191974 and rs2028299 are significantly associated with T2DM in the Chinese population.
