The study revealed that cypermethrin (CYP) induced cytotoxicity in porcine Sertoli cells (SCs) through oxidative stress, DNA damage, and apoptosis, and melatonin showed a protective effect against CYP-induced toxicity.
Cypermethrin (CYP) is a widely used insecticide that may be harmful to nontarget species. However, the toxicity of CYP to porcine Sertoli cells (SCs) and its associated mechanism is not known. We investigated the toxicity of CYP and showed that CYP induced cytotoxicity in porcine SCs in a dose-dependent manner. Mechanistic investigations revealed that CYP induced oxidative stress and DNA damage in porcine SCs, which provoked mitochondria-associated apoptosis. CYP also stimulated the phosphorylation of c-Jun N-terminal kinase (JNK) to induce porcine SC apoptosis and inhibited cell proliferation via the inhibition of nuclear factor kappa B (NFKB) expression. The natural antioxidant melatonin had an obvious protective effect against CYP-induced porcine SC toxicity. Overall, our results reveal that the mechanism underlying CYP-induced toxicity in porcine SCs involves oxidative stress, DNA damage, and apoptosis and suggest that melatonin may be used as a highly effective protective agent against oxidative stress.
