Effects of IAA exposure on gene expression of Bcl2, Bcl2l10, Bax and Aifm1, in follicles treated with 2, 5, 10 and 15 μM of IAA. RNA was extracted from snap-frozen follicles, reversed transcribed to cDNA, and subjected to quantitative real time PCR. Graphs represent means ± SEM from 3 separate cultures. Asterisks (*) indicate significant differences compared to control (P ≤ 0.05).
