1 Here we report that subchronic administration of the organochlorine insecticide heptachlor (0, 3, 6, 9, or 12 mg/kg given 3 times over a 2 week period) leads to a pronounced increase in both the plasma membrane transport of dopamine and the expression of the plasma membrane dopamine transporter (DAT), as well as the vesicular monoamine transporter (VMAT2) in the striatum of C57BL mice. Heptachlor solute carrier family 6 (neurotransmitter transporter, dopamine), member 3 Mus musculus

4 Since DAT has been proposed to be the molecular gateway for dopaminergic toxins, such as the parkinsonism-inducing neurotoxin MPP, and VMAT2 has been proposed to protect cells from MPP and other toxins by sequestering the toxin into vesicles, the combined effects of heptachlor could increase the susceptibility of the nigrostriatal dopamine system to neurodegeneration.
