The role of L-carnitine in the control of oxidative stress and lipid β-oxidation during in vitro follicle growth, oocyte maturation, embryonic development and cryopreservation: a review.
L-carnitine has an important role in the control of oxidative stress and lipid β-oxidation during in vitro culture and cryopreservation of ovarian follicles, oocytes and embryos. This substance balances the acetyl-CoA/CoA ratio, maintains glucose metabolism and increases energy production in mitochondria. It also plays a key role in reducing endoplasmic reticulum stress, by transferring palmitate to mitochondria or eliminating it to avoid toxicity. By eliminating reactive oxygen species, L-carnitine increases the percentages of mature oocytes with uniform mitochondrial distribution and improves embryo post-thaw cryotolerance. Therefore, L-carnitine controls lipid β-oxidation and oxidative stress during in vitro culture of ovarian follicles, oocyte maturation, embryonic development and cryopreservation.
期刊介绍:
An international journal dedicated to the rapid publication of original research in early embryology, Zygote covers interdisciplinary studies on gametogenesis through fertilization to gastrulation in animals and humans. The scope has been expanded to include clinical papers, molecular and developmental genetics. The editors will favour work describing fundamental processes in the cellular and molecular mechanisms of animal development, and, in particular, the identification of unifying principles in biology. Nonetheless, new technologies, review articles, debates and letters will become a prominent feature.
