In the present study, we investigated whether vascular endothelial growth factor A (VEGFA) plays a critical intraovarian survival role in gonadotropin-dependent folliculogenesis. The effect of an intrabursal administration of a VEGFA antagonist on follicular development, apoptosis, and levels of pro- and antiapoptotic proteins of BCL2 family members (BAX, BCL2, and BCL2L1), as well as of TNFRSF6 (also known as FAS) and FAS ligand (FASLG), was examined. To inhibit VEGFA, a soluble FLT1/Fc Chimera (Trap) was administered to prepubertal eCG-treated rats. Injection of 0.5 μg of Trap per ovary did not change the number of preantral follicles (PFs) or early antral follicles (EAFs); however, it significantly decreased the number of periovulatory follicles 48 h after surgery and significantly increased the number of atretic follicles. No significant differences were found in any stage of the follicles either 12 or 24 h after injection. Cells undergoing DNA fragmentation were quantified by performing TUNEL on ovarian sections. Trap treatment caused a twofold increase in the number of apoptotic cells in EAFs. DNA isolated from antral follicles incubated for 24 h exhibited the typical apoptotic DNA pattern. Follicles obtained from Trap-treated ovaries showed a significant increase in the spontaneous onset of apoptotic DNA fragmentation. The injection of Trap significantly increased the levels of BAX and decreased the levels of BCL2 protein. The ratio of BCL2L1_L:BCL2L1_s was significantly diminished in follicles obtained from ovaries treated with Trap. No changes in the levels of TNFRSF6 or FASLG were observed after treatment. We concluded that the local inhibition of VEGFA activity appears to produce an increase in ovarian apoptosis through an imbalance among the BCL2 family members, thus leading a larger number of follicles to atresia.
