Observed associations between corpora lutea and follicular development in swine ovaries during the estrous cycle.
The interovarian relationship of the number of corpora lutea with ovarian fluid weight, with number of follicles, with number of normal follicles and with number of milky follicles was studied at three different phases of the estrous cycle in sows. There was a significant association (exceeding that which would arise because of the inequality of function between the two ovaries) between-ovaries...
متن کاملLipid 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 کاملImmunopresence and functional activity of prostaglandin-endoperoxide synthases and nitric oxide synthases in bovine corpora lutea during diestrus.
The aim of this study was to evaluate the occurrence and the activity of prostaglandin-endoperoxide synthase 1 (PTGS1), PTGS2, and endothelial, neuronal, and inducible nitric oxide synthase (e-, n-, and iNOS) in early, mid, late, and regressive corpora lutea (CL) of bovines during diestrus. PTGS1 immunoreactivity was localised mainly in the cytoplasm of small luteal cells, whereas PTGS2 was det...
متن کاملMolecular characterization and expression of DERL1 in bovine ovarian follicles and corpora lutea
The endoplasmic reticulum (ER) is a major site of protein synthesis and facilitates the folding and assembly of newly synthesized proteins. Misfolded proteins are retrotranslocated across the ER membrane and destroyed at the proteasome. DERL1 is an important protein involved in the retrotranslocation and degradation of a subset of misfolded proteins from the ER. We characterized a 2617 bp cDNA ...
متن کاملExpression of fibroblast growth factor 13 (Fgf13) mRNA in bovine antral follicles and corpora lutea
Recent studies have suggested a paracrine role for several fibroblast growth factors (FGFs) in the regulation of follicle and luteal development. Fgf13 is a non-secreted FGF that has been previously localized to the developing gonads, but it is not known if it is expressed in the adult ovary. The objective of the present study was to determine the expression pattern of Fgf13 mRNA in the bovine ...
