Abstract:
... The aim of this study was to examine protein expression patterns of uterine histroph (UH) during the follicular phase (FP) and luteal phase (LP) in pigs. Forty-nine common proteins were identified from FP and LP samples; five were significantly down-regulated (>1.5-fold), while 15 were significantly up-regulated (>1.5-fold) in LPUH compared with FPUH (P<0.05). The 20 differentially-expressed prote ...

These findings have been confirmed by many studies in which the ghrelin gene was expressed in the ovary and was implicated in the control of cells in reproductive tissues. The proliferating cell nuclear antigen (PCNA) is an important marker of cell proliferation. The present study investigates ...

Abstract:
... In the ovary, angiotensin II (ANGII) acts through the type 2 receptor (AGTR2) to induce ovulation and may play a role in follicle atresia. In this study, we determined the expression of AGTR2 mRNA and protein during follicle formation in the bovine ovary. Female fetuses at different gestational ages (60, 75, 90, 120, 150 and 210 days) were used for immunolocalization of AGTR2. At day 60, AGTR2 was ...

Abstract:
... Goats are seasonal breeders and photoperiod is the main cue controlling the onset and offset of the breeding season. Nevertheless introducing a sexually active buck in a group of females during anestrous can stimulate their reproductive function and induce ovulation. This “male-effect” is very efficient under subtropical latitudes, when using sexually active males previously stimulated by a photop ...

Abstract:
... Juvenile hormone (JH) and methyl farnesoate (MF) play essential roles in the development and reproduction of insects and crustaceans respectively. Juvenile hormone acid methyltransferase (JHAMT) catalyzes the methyl esterification in insect JH biosynthesis, while the corresponding step in crustacean MF biosynthesis was long thought to be catalyzed by farnesoic acid O-methyltransferase (FAMeT).
