Biosynthesis of retinal in bovine corpus luteum.
Bovine corpus luteum tissue was sliced and incubated with beta-[15,15'-(3)H]carotene. The conversion of radioactive beta-carotene into radioactive retinal was substantiated utilizing column chromatography, thin-layer chromatography, high-speed liquid chromatography, and a derivative formation. Lowering of the incubation temperature to 20 degrees C or boiling the tissue eliminated the conversion...
متن کاملAngiogenesis in the corpus luteum
The corpus luteum (CL) is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual cycle. The molecular regulation of these diverse aspects is examined. The CL provides a unique model system in which to study the cellular and mol...
متن کاملBiology of the Corpus luteum
Corpus luteum (CL) is a small, transient endocrine gland formed following ovulation from the secretory cells of the ovarian follicles. The main function of CL is the production of progesterone, a hormone which regulates various reproductive functions. Progesterone plays a key role in the regulation of the length of estrous cycle and in the implantation of the blastocysts. Preovulatory surge of ...
متن کاملEffects of oxytocin on the bovine corpus luteum of early pregnancy.
Oxytocin, at concentrations of 4 and 40 mi.u./ml, significantly enhanced progesterone production by dispersed bovine luteal cells (0\m=.\5\p=n-\4months of gestation) after incubation for 3 h. The luteotrophic effect of 4 mi.u. oxytocin/ml was comparable to that of 10 i.u. hCG/ml. Higher oxytocin concentration (800 mi.u./ml) markedly inhibited the response of the luteal cells to hCG and may be i...
متن کاملBiochemical and endocrine aspects of oxytocin production by the mammalian corpus luteum
A review of the current state of knowledge of oxytocin production by the preovulatory follicle and corpus luteum is presented. Corpora lutea of a number of mammalian species have been found to synthesize oxytocin. However, the synthesis and secretion of this nanopeptide by the corpus luteum of the ruminant has been most extensively studied because of the potential role of this peptide in facili...
