The 90-kDa heat shock protein (HSP90) is a chaperone that is important for maintaing protein homeostasis under stress conditions. HSP90 seems also to be required for maturation of Xenopus oocytes (Fisher et al. 2000 EMBO J. 19, 1516) and first cleava

Trichostatin A (TSA), a histone deacetylase inhibitor, has been described as a potential modulator of nuclear reprogramming in bovine zygotes reconstructed by somatic cell nuclear transfer (SCNT), but with controversial results (Lee et al. 2011 J. Re

Trichostatin A is a histone deacetylase inhibitor that improves histone acetylation and chromatin remodeling of somatic cell nuclear-transferred embryos (Iager et al. 2008 Cloning Stem Cells 10, 371–379; Maalouf et al. 2009 BMC Dev. Biol. 9, 11). W

137 DIFFERENTIAL GENE EXPRESSION OF IN VITRO-MATURED BOVINE OOCYTES WITH OR WITHOUT A POLAR BODY

Oocyte competence is associated with the amount of transcripts stored in the ooplasm and oocyte ability to extrude polar bodies (PB). To our knowledge, however, no data comparing mRNA levels between bovine oocytes maturated in vitro with or without P

Heat stress has been a challenge for bovine reproduction in tropical and subtropical environments. Although the role of the oocyte in thermotolerance has been studied, little attention has been paid to the contributions of sperm to embryo resistance
