Selective activation of rabbit ovarian protein kinase isozymes in rabbit ovarian follicles and corpora lutea.
The magnitude of activation of the type I and type II forms of cAMP-dependent protein kinase was investigated in estrous follicles and corpora lutea (CL) obtained from ovaries of control rabbits and rabbits injected acutely with human chorionic gonadotropin (hCG). To this end, a chromatographic technique which permitted quantitative evaluation of the in vivo activational state of the two forms ...
متن کاملCharacterization of ovine follicles destined to form subfunctional corpora lutea.
A study was done to test whether ovulatory follicles destined to form subfunctional corpora lutea differed from normal ovulatory follicles in steroidogenic function. Twenty-five ewes were treated with prostaglandin F2 alpha on d 11 of the estrous cycle, then unilaterally ovariectomized before (n = 13) or after (n = 12) the surge of luteinizing hormone (LH) at the induced estrus to collect "cont...
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 کاملEndothelin-converting enzyme-1 is expressed on human ovarian follicles and corpora lutea of menstrual cycle and early pregnancy.
We have previously reported that membrane-bound amino- and carboxypeptidases were expressed on the human follicles and corpora lutea (CL), and we proposed that these peptidases are involved in ovarian functions, probably by regulating the extracellular peptide concentrations. In this study, we examined the expression of endothelin-converting enzyme-1 (ECE-1) on human follicles and CL, which is ...
متن کاملToxicity of Gossypol from Cottonseed Cake to Sheep Ovarian Follicles
Gossypol, a polyphenol compound produced by cotton plant, has proven reproductive toxicity, but the effects of gossypol on sheep ovaries are unknown. This study was aimed to determine the in vitro and in vivo effects of gossypol on the ovarian follicles of sheep. This trial was divided into two experiments. In the first one, we used twelve non-pregnant, nulliparous, Santa Inês crossbred ewes, w...
