We exposed PC12 cells to chlorpyrifos, diazinon or parathion in the undifferentiated state and during neurodifferentiation; we then assessed the function of the adenylyl cyclase (AC) signaling cascade, measuring basal AC activity as well as responses to stimulants acting at G-proteins or on the AC molecule itself.

OBJECTIVES: We evaluated mechanisms contributing to the adverse effects of chlorpyrifos (CPF) on DNA synthesis, cell number and size, and cell signaling mediated by adenylyl cyclase (AC) in PC12 cells, a neuronotypic cell line that recapitulates the essential features of developing mammalian neurons.

Developmental neurotoxicity caused by chlorpyrifos exposure is generally thought to target cholinesterase but chlorpyrifos may also act on cellular intermediates, such as adenylyl cyclase, that serve global functions in the coordination of cell development.

We compared organophosphates (chlorpyrifos, diazinon), an organochlorine (dieldrin) and a metal (Ni (2+)) for their effects on neuronotypic PC12 cells, assessing gene transcription involved in the cyclic AMP pathway.
Each agent was introduced during neurodifferentiation at a concentration of 30 microM for 24 or 72 h and we assessed 69 genes encoding adenylyl cyclase isoforms and regulators, G-protein alpha-and beta,gamma-subunits, protein kinase A subtypes and the phosphodiesterase family.

For example, chlorpyrifos has not produced teratogenic effects in rats when mothers are exposed on days 6-15 (Katakura Y, et al.
These effects included neuroapoptosis, decreased deoxyribonucleic acid and ribonucleic acid synthesis, abnormalities in adenylyl cyclase cascade, and neurobehavioral effects (Johnson DE, et al.

These results provide further evidence that the cortical cAMP signaling pathway may be particularly sensitive to CPF exposure in neonatal, juvenile, and adult rats, possibly due to a direct interaction between CPF (or its oxon) and mAChRs or other components of the adenylyl cyclase cascade.

In the present study, we evaluated the immediate and long-term effects of CPF exposure of rats during different developmental windows [gestational days (GD) 9-12 or 17-20, postnatal days (PN) 1-4 or 11-14] on the adenylyl cyclase (AC) signaling cascade in the heart and liver.
