AAPH-treated blastocysts vs CTL-treated blastocysts
Ontology highlight
ABSTRACT: In order to understand how in vitro culture affects embryonic quality, we analyzed survival and global gene expression in bovine blastocysts after exposure to increased oxidative stress conditions of IVC. A pro-oxidant agents that act extra-cellularly by promoting ROS production (0.01 mM 2,2'-azobis (2-amidinopropane) dihydrochloride [AAPH]) was added from days 3 to 7, and transcriptomic analysis was then performed in resulting blastocysts. Precisely, after in vitro maturation and fertilization, bovine zygotes were culture in vitro in normal condition, then at day 3, embryos were allocated into culture in control or supplemented with AAPH (0.01 mM) until day 7. At this time, blastocysts were harvested and analyzed. Our hypothesis was that AAPH treatment will affect blastocyst survival and gene expression associated with low embryo quality 4 replicates of 10 blast/rep was produced for AAPH and control treatment. According to a dye swap design with 2 colors, 4 arrays were used to compare AAPH (green) against CTL (red) and 4 arrays were used to compared AAPH (red) againt CTL (green).
