Effect of trans-ε-viniferin on in vitro porcine oocyte maturation and subsequent developmental competence in preimplantation embryos.

ABSTRACT: Trans-ε-viniferin is a naturally occurring polyphenol belonging to the stilbenoid family that has been isolated from Vitis amurensis, one of the most common wild grapes in Asia. We investigated the effects of trans-ε-viniferin on in vitro maturation (IVM) and developmental competence after in vitro fertilization (IVF) or parthenogenesis (PA). We observed that trans-ε-viniferin treatment during IVM did not improve nuclear maturation rates of oocytes in any group, but significantly increased (P<0.05) intracellular glutathione (GSH) levels and reduced reactive oxygen species (ROS) levels in the 0.5 μM treatment group. Trans-ε-viniferin treatment during IVM of recipient oocytes promoted higher (P<0.05) expression of DNA methyltransferase-1 (DNMT1) mRNA in the 0.5 μM treatment group as compared
