Dichlorodiphenyltrichloroethane suppresses neurite outgrowth and induces apoptosis in PC12 pheochromocytoma cells.

abstract：:There are multiple lines of evidence showing that environmental toxicants including pesticides may contribute to neuronal cell death. Fipronil (FPN) is a phenylpyrazole insecticide that acts on insect GABA receptors. Although the action of FPN is restricted to insect neuronal or muscular transmitter systems, a few stu...
