We have previously shown that in PC12 cells: (1) high extracellular KCl induces moesin phosphorylation, an event which was dependent on chloride channel activation, and (2) NGF induces moesin phosphorylation which is required for neurite outgrowth. These results suggest that NGF-induced intracellular signaling and neurite outgrowth is also mediated by activation of anion channels. Using a patch-clamp technique, we found that NGF treatment increased anionic conductance in PC12 cells, an effect which was completely blocked by NPPB, a chloride channel inhibitor. Also, the NGF-induced moesin phosphorylation was suppressed by NPPB. Additionally, NPPB and SITS, another chloride channel blocker, suppressed NGF-induced TrkA phosphorylation and subsequent PI3K/Akt phosphorylation and Rac1 activation in PC12 cells. Moreover, the chloride channel inhibitors also suppressed the neurite outgrowth and decreased the cell viability in response to long-term treatment of NGF. In summary, our results suggest that chloride ion flux plays an important role in TrkA-mediated signaling pathway during NGF-induced differentiation of PC12 cells.

D015398 Signal Transduction The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
