Prostaglandin F2α promotes ovulation in prepubertal heifers.
The objective was to determine the effects of exogenous prostaglandin F(2α) (PGF), with or without progesterone treatment, on first ovulation in prepubertal heifers. We tested the hypothesis that PGF has a luteolysis-independent ovulatory effect in cattle. Crossbred Angus heifers (12 to 14 mo old, 250 kg body weight, and an average body condition score of 3 out of 5) were examined by transrecta...
متن کاملNew evidence for the involvement of prostaglandin receptor EP4b in ovulation of the medaka, Oryzias latipes.
A cDNA for a prostaglandin E(2) (PGE(2)) receptor subtype 4, EP4b (Ptger4b), was cloned from the medaka ovary. The effect of PGE(2) was examined using COS-7 cells expressing the recombinant Ptger4b protein. An increase in intracellular cAMP levels was observed when the cells were incubated with PGE(2), but the increase in cAMP levels was nullified by the addition of the EP4 antagonist GW627368X...
متن کاملRegulation of prostaglandin-endoperoxide synthase 2 messenger ribonucleic acid expression in mouse granulosa cells during ovulation.
Normal ovulation in mice requires PG-endoperoxide synthase 2 (cyclooxygenase-2; COX-2) expression. This study examined the role of the oocyte and other factors in regulating steady state levels of COX-2 messenger RNA (mRNA) in granulosa cells. Multiphasic changes in the expression pattern of COX-2 mRNA were found, with peaks of expression 4 and 12 h after hCG treatment. Changes in relative expr...
متن کاملPreventive Powers of Ovulation and Progesterone Ovulation and the Heart
We have been asking, through a series of newsletters, what we know about women’s health related to normal progesterone levels and ovulation. We have discussed the fact that ovulatory disturbances (meaning anovulation and short luteal phase cycles) are common and hidden within menstrual cycles that seem perfectly normal. I speculate that at least a third of all cycles in regularly menstruating, ...
