Effects of adiponectin during in vitro maturation of goat oocytes: MEK 1/2 pathway and gene expression pattern.

Recent studies have shown that adiponectin, an adipokine predominantly produced by adipose tissue, regulates several reproductive processes. However, the mechanisms of action of adiponectin on the maturation of goat oocytes remain to be determined. The aim of this study was to investigate whether (a) adiponectin influences the meiotic maturation of goat oocytes; (b) MAPK MEK 1/2 mediates the effects of adiponectin; and 3) adiponectin differentially affects mRNA relative abundance of genes relevant for adiponectin signal transduction in goat oocytes.
