Opis:
Nowadays non-alcoholic fatty liver disease (NAFLD) is becoming the most common chronic liver pathology both in adults and children. NAFLD manifestation ranges from a simple liver steatosis to steatohepatitis (nonalcoholic steatohepatitis - NASH), which may progress to advanced fibrosis, cirrhosis and end-stage liver disease. Due to the coexistence of visceral obesity, insulin resistance and dyslipidemia, NAFLD is considered to be the hepatic manifestation of metabolic syndrome. In recent years, in the pathogenesis of metabolic syndrome, type 2 diabetes mellitus, cardiovascular disease and also NAFLD, more and more attention has been paid to the so-called organokines, proteins with both paracrine or/and endocrine activities. These include most known adipokines (mainly produced by adipose tissue), myokines (mainly produced by skeletal muscles) and hepatokines exclusively or predominantly produced by the liver. It was shown that the liver may affect the lipids and glucose metabolism by hepatokines released into the blood and NAFLD seems to be associated with altered hepatokines production. Fetuin-A, fibroblast growth factor-21 (FGF-21), selenoprotein P, sex hormone-binding globulin (SHBG), angiopoietin-related growth factor (also known as angiopoietin-related protein 6) and leukocyte derived chemotaxin 2 (LECT2) are considered as the most important hepatokines. In this review, we provide an overview of the main hepatokines and we summarize the association of liver-derived proteins with the development and progression of NAFLD.

Opis:
Diagnosis of lung cancer (LC) has been fraught with difficulty and by the time of definitive diagnosis, most patients are in later stages of the disease. Epidemiological studies have demonstrated that lifestyle behaviors play an etiological role in LC risk; however data in the literature on this topic often appears inconclusive or require further study. Understanding of the mechanisms operating between lifestyle patterns and their impact on LC is important for the disease’s prevention and treatment. The purpose of this study was to review the current evidence on the role of diet, body mass index (BMI), physical activity, smoking, alcohol consumption, and sex hormone use in LC development based on meta-analyses, systematic reviews and previously published epidemiologic studies. Regarded as the foremost cause of LC, evidence from studies have indicated that tobacco smoking causes LC. Additionally, exposure to outdoor air pollution and/or occupational-related exposures increase LC risk. Further, frequent consumption of red meat, processed meat increases adenocarcinoma and squamous cell carcinoma. Inverse associations between the disease risk and BMI ≥25 kg/m2, higher level of physical activity, and fruit and vegetable consumption with a high frequency were reported. Future studies are warranted to validate the association between histologic subtypes of LC and lifestyle patterns.

Opis:
Introduction and objective. Phytoestrogens are one of nutritional factors exhibiting a chemoprotective action, potentially reducing vasomotor symptoms as well as cancerous lesions. The study was ocused on an association between the consumption of phytoestrogens in the diet, blood serum cholesterol concentration and urinary estrogen metabolites levels. Materials and methods. The study was conducted on 55 women in the perimenopausal period, who were characterized by an increased risk of hormone-dependent cancer. Energy and nutritive value of food rations, and especially the level of phytoestrogen consumption in the diets in the examined population, were analyzed using the Wikt Pro computer programme. Estrogen metabolites (2OHE, 16α-OHE1) were determined from 24‑urine samples by the ELISA method. The EMR index was calculated. Plasma total cholesterol concentrations was measured. Results and conclusions. The population with a higher consumption of phytoestrogens and dietary fibre in the diet, at the simultaneous slight limitation of energy value of the food ration, is characterized by an improved blood serum cholesterol concentration and an appropriate estrogen metabolism towards a significant increase in the estrogen index for the cancer lesions in the mammary glands.

Opis:
Adult males of Schistocerca gregaria turn yellow when they become sexually mature. This is due to the deposition in the cuticle of a male-specific Yellow Protein (YP), of which the amino acid sequence is known. Yellowing only happens in crowd-reared (gregarious) males, and results from the deposition of a specific ‘Yellow Protein’. If individual males (solitarious) are isolated after the adult emergence, they become sexually mature but they do not turn yellow. On the basis of a partial YP-mRNA sequence, we established a reverse transcriptase polymerase chain reaction (RT-PCR) assay to study the developmental expression of YP in crowd-reared males, isolated-reared males and females. In crowd-reared adult males the transcription of YP gene started from day 5 on, and reached a maximum at day 12. The effects of juvenile hormone (JH), insulin (bovine), corazonin, ecdysone and 20 0H-ecdysone (20E) on the regulation of YP-mRNA synthesis were also investigated. JH made the cuticle turn yellow and, as shown by RT-PCR, YP-mRNA was induced. The effect of 100 μg JHIII was stronger than that of 10 μg. Insulin was only effective in inducing YP-mRNA synthesis at high dose (19 μg) and after more days (18 d). Corazonin and 20E made the cuticle turn black, but no YP-mRNA synthesis was observed. Ecdysone (10 and 100 μg) showed no effect on body coloration and YP-mRNA. Thus, JH was found to be the most potent inducer among the hormones tested.
