Anti-apoptotic properties of carbon monoxide in porcine oocyte during in vitro aging
If fertilization of matured oocyte does not occur, unfertilized oocyte undergoes aging, resulting in a time-dependent reduction of the oocyte's quality. The aging of porcine oocytes can lead to apoptosis. Carbon monoxide (CO), a signal molecule produced by the heme oxygenase (HO), possesses cytoprotective and anti-apoptotic effects that have been described in somatic cells. However, the effects...
متن کاملMelatonin prevents postovulatory oocyte aging and promotes subsequent embryonic development in the pig
Oxidative stress is known as a major contributing factor involved in oocyte aging, which negatively affects oocyte quality and development after fertilization. Melatonin is an effective free radical scavenger and its metabolites AFMK and AMK are powerful detoxifiers that eliminate free radicals. In this study, we used porcine oocytes to test the hypothesis that melatonin could scavenge free rad...
متن کاملIn vitro effects of relaxin on gene expression in porcine cumulus-oocyte complexes and developing embryos
BACKGROUND Relaxin hormone peptide is found in porcine follicular and utero-tubal fluids, but its possible actions during early embryo development are still undetermined. Here, we investigated the effects of porcine relaxin during oocyte maturation and embryo development, and gene expression in the pig. METHODS Immature cumulus-oocyte complexes (COCs) were obtained from ovarian follicles of s...
متن کاملProtein Profile Changes during Porcine Oocyte Aging and Effects of Caffeine on Protein Expression Patterns
It has been shown that oocyte aging critically affects reproduction and development. By using proteomic tools, in the present study, changes in protein profiles during porcine oocyte aging and effects of caffeine on oocyte aging were investigated. By comparing control MII oocytes with aging MII oocytes, we identified 23 proteins that were up-regulated and 3 proteins that were down-regulated dur...
