Fig. 1.

Transcription profiles of (a, b) PGE₂ synthases: PTGS2, PTGES, PTGES2, PTGES3, and (c, d) PGE₂ receptors: PTGER1, PTGER2, PTGER3, PTGER4 in bovine oocytes (a, c) and cumulus cells (b, d) after IVM. The values are presented as arbitrary units and are expressed as the means ± SEM of eight independent repeats (10 oocytes and all cumulus cells separated from the respective oocytes in each replicate). Different letters indicate significant differences (P < 0.05), as determined by one-way ANOVA followed by Tukey’s multiple comparison test
