Effect of etomoxir (150 μM) on oocyte maturation and signaling pathways. A. Phosphorylation of MAPK3/1 in bovine oocytes after 6 h IVM B. Oocyte maturation rate at 18 h IVM in the presence or absence of etomoxir. C. MAPK14 and MAPK3/1 phosphorylation in CC after 18 h IVM in the presence or absence of etomoxir. Histograms correspond to mean ratio +/−SEM of 4 independent replicates. Mann–Whitney test was performed. Asterisks denote significant difference; *p < 0.05, **p < 0.01, ***p < 0.001.
