Abstract

OBJECTIVES: We evaluated the effect of melatonin, as a potent antioxidant agent, on glutathione (GSH) and reactive oxygen species (ROS) levels, as well as histone H3 lysine 9 (H3K9), and H4 lysine 12 (H4K12) acetylation when added to oocytes culture medium.

MATERIALS AND METHODS: In this experimental study, two in vitro and in vivo groups were used. In the in vitro group, cumulus oocyte complexes (COCs) from the ovaries of B6D2F1 mice were cultured in maturation medium containing two doses of melatonin (10

RESULTS: The H4K12 acetylation and ROS levels were significantly higher in the oocytes matured in the in vitro group compared to the in vivo group (P<0.05). Furthermore, glutathione levels in the in vitro group were considerably lower than that of the in vivo group (P<0.05). Melatonin at the concentration of 10

CONCLUSIONS: Exogenous melatonin improves the competence of mouse oocytes during in vitro maturation (IVM).
