Venn diagram of differently expressed genes. The graph showing genes modulated according to a cut off set at 1.5 for symmetrical fold change and a p-value < 0.05. 2,942 differentially expressed genes between plateau (P) and growing (G) follicle granulosa samples. The atretic (A) versus plateau (P) contrast yielded 1974 differentially expressed genes. 932 genes modulated in both contrasts.
