Hormonal Regulation of Nitric Oxide Synthases and Their Cell-Specific Expression during Follicular Development in the Rat Ovary1.
Nitric oxide (NO) has emerged as a novel regulator of several ovarian events, such as ovulation, steroidogenesis, and apoptotic cell death. The NO synthases (NOS) are a family of enzymes that catalyze the oxidation of L-arginine to NO and L-citrulline. The purpose of the present study was to localize NOS isoforms in the rat ovary and to examine their hormonal regulation. We conducted immunohist...

Regulation of cell death and cell survival gene expression during ovarian follicular development and atresia.
Mammalian ovarian follicular development and atresia is closely regulated by the cross talk of cell death and cell survival signals, which include endocrine hormones (gonadotropins) and intra-ovarian regulators (gonadal steroids, cytokines and growth factors). The fate of the follicle is dependent on a delicate balance in the expression and actions of factors promoting follicular cell prolifera...
متن کاملRegulation of Follicular Growth and Development in Sheep
This manuscript reviews the present knowledge related to folliculogenesis in sheep.Folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. By the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. The number of growing primord...
