Mitochondria and MAPK cascades modulate endosulfan-induced germline apoptosis in Caenorhabditis elegans.

ABSTRACT: Endosulfan as a new member of persistent organic pollutants has been shown to induce apoptosis in various animal models. However, the mechanism underlying endosulfan-induced apoptosis has not been well elucidated thus far. Caenorhabditis elegans N2 wild type and mutant strains were used in the present study to clarify the roles of the mitochondria, the insulin/insulin-like growth factor-1 (IGF-1) signaling pathway, and mitogen-activated protein kinase (MAPK) cascades in α-endosulfan-induced apoptosis. Our results demonstrated a dose- and time-dependent increase of apoptosis in the meiotic zone of the gonad of C. elegans exposed to graded concentrations of endosulfan. The expression levels of sod-3, localized in the mitochondrial matrix, increased greatly after endosulf
