Orexin A promotes granulosa cell secretion of progesterone in sheep
Background: Orexin A, a small-molecule peptide, can regulate female hormones, but limited evidence for its mechanism of activity exists in ovine. Aims: The objective of this study was to investigate the effect of orexin A on progesterone (P4) secretion in cultured granulosa of sheep follicles. Methods: Sheep ovarian granulosa were isolated and ...
متن کاملEffect of Follicular Fluid Proteins and Gonadotropins on Progesterone Secretion by Buffalo Granulosa Cells In vitro
In the mammalian ovary the follicular fluid contains proteins and peptides which play an important role in growth, development and maturation of oocytes. The gonadotropins and some other factors work synergistically and regulate ovarian functions. In the present study the effect of follicular fluid proteins (FFP) and gonadotropins on progesterone secretion by granulosa cells (GC) from buffalo o...
متن کاملInhibitory effects of the porcine follicular fluid on estradiol and progesterone secretion by cultured rat granulosa cells.
The effect of porcine follicular fluid on estradiol and progesterone secretion was examined using a rat granulosa cell culture with FSH and testosterone in the medium. Follicular fluids from small (less than 5 mm) and large (greater than 6 mm) follicles (SFFI, LFF1) were treated with charcoal, and then fractionated by filtration through an Amicon XM-50 and an PM-10 membrane. The addition of 25%...
