In the hepatic tissues, the greatest increases in activities were observed with TCDD, chlorpyrifos, endrin and Cd (II), while chlorpyrifos and fenthion exerted the greatest increases in the brain tissues.

Ann N Y Acad Sci. 2004 Oct;1025:595-601.

Two otherwise unrelated agents that converge on cholinergic systems, chlorpyrifos and nicotine, elicited the same spectrum of effects on PKC isoforms and imprinting but had more robust actions.

ERK 44/42 activation by CPO is insensitive to the protein kinase A inhibitor H-89, but is completely abolished by the phosphatidylinositol 3-kinase (P13-K) inhibitor wortmannin, the protein kinase C (PKC) inhibitor GF-109203X, and the mitogen-activated extracellular signal-regulated protein kinase kinase (MEK) inhibitor PD 098059.

This activation is blocked by inhibitors of protein kinase C and mitogen-activated protein kinase kinase, suggesting that these enzymes are important in CPO/DAG cellular signaling.

Studies with cholinergic receptor blocking agents and protein kinase C inhibitors indicated two distinct types of effects, one mediated through stimulation of nicotinic cholinergic receptors and the other targeting intracellular signaling.
