Research Abstract

Follicular growth and maturation are known to be regulated by intra-ovarian factors, although the mechanisms are still to be known. Recently, unfolded protain response (UPR) has been known to have essential roles in keeping homeostasis. In the present study, to test whether UPR in granulosa cells (GC) and cumulus cells (CC) is involved in the process of follicular growth and maturation, we examined the presence of UPR in GC during follicular growth and the association between UPR expression in CC and oocyte maturity. UPR-related genes, spliced form of X-box binding protein -1 (XBP1(S)) and heat shock 70kDa protein 5 (HSPA5), were expressed in mice GC of growing follicels, and their expression is stage-dependent. In addition, the expression levels of XBP1(S) mRNA in CC enclosing human mature oocytes were 2-fold higher than those in CC enclosing immature ooytes. These findings suggest that UPR is activated in GC during follicular growth, playing roles in follicular growth and maturation.
