Lipid metabolism in regressing rat corpora lutea of pregnancy.
Lipid accumulation is a hallmark of corpus luteum regression and we characterized lipids stored in rat corpora lutea of pregnancy between days 21 and 24 post coitum, the period of luteolysis. A 10-fold rise in lutein triglyceride concentrations occurred between days 21 and 24, which represented the major alteration in luteal lipid metabolism during luteolysis, coinciding with the appearance of ...
متن کاملExogenous estradiol enhances apoptosis in regressing post-partum rat corpora lutea possibly mediated by prolactin
BACKGROUND In pregnant rats, structural luteal regression takes place after parturition and is associated with cell death by apoptosis. We have recently shown that the hormonal environment is responsible for the fate of the corpora lutea (CL). Changing the levels of circulating hormones in post-partum rats, either by injecting androgen, progesterone, or by allowing dams to suckle, was coupled w...
متن کاملEffects of corpora lutea removal and replacement with progesterone on pregnancy in goats.
p ROGESTERONE is predominantly a hormone of pregnancy and is required for (a) the growth and secretion of the glands in the uterine mucosa preparatory to implantation of the ovum (b) the nutrition and protection of the embryo during the time when it is lying free in the uterus (c) the development of the placenta and membranes after implantation (d) lobule-alveolar mammary growth (e) maintenance...
متن کاملComparison of induced corpora lutea from prepuberal gilts and spontaneous corpora lutea from mature gilts: in vitro progesterone production.
Prepuberal (P) gilts were induced to ovulate with pregnant mare serum gonadotropin followed 72 h later by human chorionic gonadotropin (hCG). Three P gilts and three mature (M) gilts each were ovariectomized on d 10, 14, 18, 22 and 26 (d 0 = day of hCG for P gilts and onset of estrus for M gilts). Gilts ovariectomized on d 14, 18, 22 and 26 were hysterectomized on d 6 to ensure maintenance of t...
متن کاملInduction of peroxidase in corpora lutea of rat ovary by lutropin.
The lutropin-induced depletion of ascorbate in corpora lutea of albino-rat ovary is shown to be associated with the induction of peroxidase in corpora lutea. An inverse relationship between ascorbate depletion and peroxidase activity was established in a time-course study with lutropin. Analyses made at different phases of the reproductive cycle are in accord with this relationship. It is sugge...
