NAMPT and polycystic ovary syndrome: Our study revealed that overexpressed XIST interacts with both hsa-miR-144-3p, and hsa-miR-146a-5p as the competing endogenous RNA to increase LCP2 expression in GCs of PCOS individuals.Nicotinamide phosphoribosyltransferase (NAMPT), also known as a visfatin, is a 52 kDa mammalian homodimeric adipokine47 that is expressed in several tissues, including GCs of the ovary48–50.
