The endocrine profile of subcutaneous and visceral adipose tissue of obese patients.

The aim of the present study was to evaluate the expression profile of genes potentially related to metabolic complications of obesity in the whole adipose tissue and isolated adipocytes from subcutaneous (SAT) and visceral adipose tissue (VAT) from 12 non-diabetic obese women and 12 lean women. Real-time polymerase chain reaction was used for expression analysis of 41 genes of interest and two housekeeping genes. We found increased expression of specific proinflammatory and adipogenic genes and reduced expression of specific lipogenic and insulin signaling pathway genes in obese relative to lean women with no preferable localization in SAT or VAT depot.

Genetic polymorphisms as a risk factor for anorexia nervosa.

Anorexia nervosa (AN) is an eating disorder affecting mostly young people which could lead to serious complications and consequences. There are ethnical and gender differences in the incidence and prevalence of AN, but the influence of urbanization has not yet been proved. The relationship of genetic background to the risk of AN is still being investigated.

[The influence of obesity on the gene expression of adiponectin and its receptor in subcutaneous adipose tissue].

Unlabelled: The objective of the study was to measure the concentration of adiponectin in plasma, its mRNA expression and the expression of the adiponectin receptors AdipoR1 and AdipoR2 in subcutaneous adpipose tissue (ST) of women with various levels of fat in their organism. A further objective of the study was to determine to what extent the stated parameters correlate with obesity as defined by BMI (body mass index) and how it can be affected by a very low calorie diet (VLCD).

Patient Sample: The sample of 70 women was divided into groups by BMI: patients with class 3 obesity (BMI > 40 kg.

Increased angiotensinogen production in epicardial adipose tissue during cardiac surgery: possible role in a postoperative insulin resistance.

Critical illness induces among other events production of proinflammatory cytokines that in turn interfere with insulin signaling cascade and induce insulin resistance on a postreceptor level. Recently, local renin-angiotensin system of adipose tissue has been suggested as a possible contributor to the development of insulin resistance in patients with obesity. The aim of our study was to determine local changes of the renin-angiotensin system of subcutaneous and epicardial adipose tissue during a major cardiac surgery, which may serve as a model of an acute stress potentially affecting endocrine function of adipose tissue.

Comparison of manual and automatic (MagNA Pure) isolation methods of total RNA from adipose tissue.

Aim: Comparison of manual and automatic (MagNA Pure) isolation methods of total RNA from adipose tissue with respect to its quality and recovery factor.

Material: 120 human subcutaneous adipose tissue samples (about 100 mg/sample) were collected from patients during surgical operations. The tissue sample was stabilized in RNAlater (QIAGEN GmbH, Germany).
