The aim of por in-vitro studies was to examine the involvement of transcription factor NF-kB (p50/p50, p65/p65) and FSH in control of porcine ovarian granulosa cells functions and the possible role of dimers p50/p50, p65/p65 in mediating FSH actions on these cells. Monolayer of primary granulosa cells was transfected with plasmids encoding human p50 cDNA and p65 cDNA, and cultured with or without addition of FSH (0, 1, 10 or 100 ng/ml). The accumulation of proteins p50 and p65...

The recent original data concerning interrelationships between metabolic hormones (ghrelin, leptin, obestatin) and feeding, action of metabolic hormones on basic ovarian functions (proliferation, apoptosis, secretory activity, response to gonadotropins, oocyte maturation) and intracellular mechanisms of its action in different species (rabbit, pig, human, chicken) are reviewed. It was shown, that metabolic hormones ghrelin, leptin and obestatin can control proliferation, apopt...
