Introduction: Visfatin belongs to adipokines, i.e. hormones produced mainly by adipose tissue; its expression and role have been described in many organs, where it regulates energy metabolism, insulin resistance and inflammatory reactions. Moreover, the level of visfatin changes during pregnancy and in obese women and those with obesity related pregnancy pathologies: preeclampsia (PE), gestational diabetes (GDM) or intrauterine growth restriction (IUGR) its level increases. Th...

Introduction: Asprosin, a novel adipokine, is a circulating hormone mainly secreted by white adipose tissue. Asprosin is encoded by the penultimate 2 exons of the fibrillin 1 (FBN1) gene. Protein product of FBN1 is profibrillin-1, which undergoes a proteolytic cleavage by furin enzyme to produce mature fibrillin-1 and asprosin. Literature data indicated that asprosin is involved in the development of diabetes, obesity, cardiomyopathy, cancer, and polycystic o...

Introduction: Omentin, also known as intelectin-1 (ITLN1), is a novel adipokine produced predominantly by visceral adipose tissue, which improves insulin sensitivity. Decreased levels of ITLN1 have been reported in the serum of obese and polycystic ovary syndrome patients, as well as in the serum and adipose tissue of obese Meishan (MS) compared to normal weight Large White (LW) pigs. However, the role of ITLN1 in female reproduction at different metabolic status is still unkn...

To maintain proper fertility the balance between formation and luteolysis of corpus luteum (CL) are necessary and strictly controlled events in female reproduction. Degeneration of CL is correlated with apoptosis and autophagy as well as connected with decreased progesterone (P4) level. Resistin is a new key player in the regulation of luteal cells function; our previously study showed that resistin have negative effect on P4 synthesis. Thus the aim of the present study was to...
