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.

Opis:
Olanzapina to atypowy lek przeciwpsychotyczny (neuroleptyk) stosowany przede wszystkim w leczeniu schizofrenii. Lek metabolizowany jest głównie przez wątrobowe enzymy cytochromu P450, CYP1A2 i CYP2D6. W metabolizm zaangażowane są również enzymy glukuronidowe, UGT1A i UGT2B10. Olanzapina u niektórych pacjentów wywołuje metaboliczne efekty uboczne, takie jak przyrost masy ciała, a także wzrost poziomu: glukozy, lipidów oraz prolaktyny. Badania farmakogenetyczne wskazują, że polimorfizmy w genach kodujących enzymy metabolizujące lek, transportery oraz inne białka zaangażowane w procesy metaboliczne mogą pomóc wyjaśnić zróżnicowaną odpowiedź pacjentów na leczenie olanzapiną. Zatem profilowanie genetyczne mogłoby być przydatne w praktyce klinicznej, głównie w celu wytypowania pacjentów z podwyższonym ryzykiem wystąpienia działań niepożądanych. Możliwość spersonalizowania terapii ułatwiłaby osiągnięcie pożądanego efektu terapeutycznego i zminimalizowała efekty uboczne.
Olanzapine is an atypical antipsychotic (neuroleptic) used primarily to treat schizophrenia. The drug is mainly metabolized by the hepatic cytochrome P450 enzymes, CYP1A2 and CYP2D6. The glucuronide enzymes UGT1A and UGT2B10 are also involved in its metabolism. In some patients, olanzapine causes metabolic side effects, such as weight gain, an increase in glucose and lipid levels, and an increase in prolactin levels. Pharmacogenetic studies indicate that polymorphisms in genes encoding drug-metabolizing enzymes, transporters, and other proteins involved in metabolic pathways, may help explain the interindividual differences in response to olanzapine treatment. Thus, genetic profiling could be useful in clinical practice, mainly to identify patients with an increased risk of adverse events. The ability to personalize therapy would facilitate maximizing therapeutic efficacy and minimizing side effects.

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:
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.

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.

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:
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.

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.

Objectives To investigate 4 loci of 3 HSP70 genes in caustic soda production plant former workers, who have been exposed to metallic mercury vapors for a long time, and including numerous cases of chronic mercury intoxication (CMI). Material and Methods Polymorphisms in HSP70 gene family members (HSP1A1 (+190G/C, rs1043618), HSPA1B (+1267A/G and +2074G/C, rs1061581) and HSP1AL (+2437T/C, rs2227956)) genes were studied among 120 male workers involved in caustic soda production by mercury electrolysis at 2 plants in Eastern Siberia. These subjects had been chronically exposed to metallic mercury vapors for > 5 years and divided into 3 groups based on the occurrence and time of the CMI diagnosis, or absence of this disease. The Group 1 consisted of individuals (N = 46), who had had contact with mercury but were not diagnosed with the CMI. The Group 2 included workers (N = 56), who were diagnosed with the CMI longer than 14 years ago. The Group 3 consisted of the subjects (N = 18), who had been diagnosed with the CMI 3–5 years ago. The logistic regression analysis was used for 3 genetic models with and without adjustment for age and duration of mercury vapor exposure. Results We found that genotypes СС-HSPA1A (+190G/C) and GG-HSPA1B (+1267A/G) had a high predictive risk of the CMI development (adjusted odds ratio ($\text{OR}_\text{adj}$) = 5.58, p = 0.026 and $\text{OR}_\text{adj}$ = 14.7, p = 0.0015, respectively). Twelve individuals with the CMI had a specific combination of СС-HSPA1A (+190G/C) and GG-HSPA1B (+1267A/G) genotypes, which strongly associated with the diagnosis ($\text{OR}_\text{adj}$ = 12.3, p = 0.0285). Moreover, significant association with the CMI was also obtained for the haplotype G-C of 1267A/G and 190G/C polymorphisms (OR = 2.1, p = 0.018). Conclusions The association of СС-HSPA1A (+190G/C) and GG-HSPA1B (+1267A/G) genotypes and their combination for the CMI individuals suggests the role for HSPA1 genes in mercury-dependent mechanisms of the CMI development and progression.

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.

Opis:
The adaptation of an athlete to systematic physical exercise has been shown to be determined by a combination of great many genes. 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:
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:
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.
