https://www.selleckchem.com/products/irak-1-4-inhibitor-i.html Vaspin, visceral adipose tissue-derived serine protease inhibitor, is involved in the development of obesity, insulin resistance, inflammation and energy metabolism. Our previous study showed vaspin expression and its regulation in the ovary; however, the role of this adipokine in ovarian cells has never been studied. Here, we studied in vitro the effect of vaspin on various kinase signaling pathways mitogen-activated kinase (MAP3/1), serine/threonine kinase (AKT), signal transducer and activator of transcription 3 (STAT3) protein kinase AMP (PRKAA1), protein kinase A (PKA) and on expression of nuclear factor kappa B (NFKB2) as well as on steroid synthesis by porcine ovarian cells. By Western blot, we found that vaspin (1 ng/ml), in a time-dependent manner, increased phosphorylation of MAP3/1, AKT, STAT3, PRKAA1 and PKA, while it decreased expression of NFKB2. We observed that vaspin, in a dose-dependent manner, increased basal steroid hormones secretion (progesterone and estradiol), mRNA and protein expression of steroid enzymes using real-time PCR and Western blot, respectively, and the mRNA of gonadotropins (FSHR, LHCGR) and steroids (PGR, ESR2) receptors. The stimulatory effect of vaspin on basal steroidogenesis was reversed when ovarian cells were cultured in the presence of a PKA pharmacological inhibitor (KT5720) and when GRP78 receptor was knocked down (siRNA). However, in the presence of insulin-like growth factor type 1 and gonadotropins, vaspin reduced steroidogenesis. Thus, vaspin, by activation of various signaling pathways and stimulation of basal steroid production via GRP78 receptor and PKA, could be a new regulator of porcine ovarian function. © The Author(s) 2020.
