Molecular regulation of progesterone synthesis in the bovine corpus luteum
In bovine luteal cells, progesterone can directly affect its own synthesis by increasing the activity of 3β-HSD. The effect of progesterone on its own secretion coincides with increased expression of the genes for 3βHSD, StAR, and cytochrome P450scc. Therefore, progesterone regulates its own synthesis by affecting the activity of the enzymes that take part in luteal steroidogenesis, and also by...
متن کاملRegulation of progesterone synthesis and action in bovine corpus luteum.
The main function of the corpus luteum (CL) is to synthesize and secrete progesterone (P4), which regulates the duration of the estrous cycle and maintains of pregnancy in many species. Both synthesis and action of this hormone is regulated by many luteotropic and luteolytic factors. Progesterone also affects its own synthesis by regulation of the activity and genes expression of crucial enzyme...
متن کاملLeucocyte proliferation in the bovine corpus luteum.
Leucocytes vary in type and number during the lifespan of a corpus luteum. The aim of this study was to determine whether there is an increase in the number of lymphocytes and macrophages as a result of local proliferation. Bovine corpora lutea were classified into stages of development, secretion and regression. A new double immunolabelling method was established for nuclear Ki-67 antigen (a m...
متن کاملBiosynthesis 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 کاملGenomic profiling of bovine corpus luteum maturation
To unveil novel global changes associated with corpus luteum (CL) maturation, we analyzed transcriptome data for the bovine CL on days 4 and 11, representing the developing vs. mature gland. Our analyses revealed 681 differentially expressed genes (363 and 318 on day 4 and 11, respectively), with ≥2 fold change and FDR of <5%. Different gene ontology (GO) categories were represented prominently...
