FGF21 has recently emerged as a major regulator of metabolism and energy utilisation. FGF21 administration confers multiple metabolic benefits on insulin sensitivity, blood glucose, lipid profile and body weight in rodents and primates. FGF21 acts through a receptor complex consisting of FGF receptors (FGFR 1, 2, 3 or 4) and a co-receptor βKlotho (KLB), crucially required for FGF21 signaling. Although FGFRs are widely expressed, KLB is predominantly expressed in adipose t...

Glypican-4 (Gpc-4) is novel adipokine interact with insulin receptor and affects insulin sensitivity in proteoglycans. Gpc-4 serum levels show gender differences; females having higher levels than men, what can suggest mediation by sex hormones. We investigated serum Gpc-4 levels and its association with cardiovascular risk predictors in women (20–35 years old) with PCOS (n=62) and healthy control (n=43) presented different sex hormones profile. The foll...

Inappropriately high secretion of aldosterone can lead to hypertension and its various cardiovascular consequences. We previously showed that microRNA (miRNA) plays a significant role in the regulation of aldosterone biosynthesis. In this study we measured miRNA levels in H295R cells, the most commonly-used human adrenocortical cell line, and investigated how these change in response to the stimulation of aldosterone biosynthesis.H295R cells (n=...

The peptides acylated and unacylated ghrelin (AG and UAG) are produced predominantly in the stomach. AG is the only known circulating orexigenic hormone with obesogenic and insulin-desensitising properties. Recent evidence suggests that UAG can inhibit these activities of AG. To investigate potential inhibitory effects of UAG and AZP-531, a UAG analogue, on AG-induced appetite and obesity we used an established rat model of diet induced obesity. Animals were fed a high-fat die...

Background: The SCOUT trial showed that sibutramine produced weight loss with some increased cardiovascular morbidity but not mortality. But these results should not be extrapolated to a routine practice as a lot of the SCOUT participants had contraindications for sibutramine. In order to summarise data on efficacy and safety of sibutramine administration in routine clinical practice according to approved indications and to implement risks monitoring system in Russia, PRIMAVER...
