Requires Activation of the Ras Pathway

We have shown that N-acetylcysteine (NAC) promotes
survival of sympathetic neurons and pheochromocytoma (PC12) cells in
the absence of trophic factors. This action of NAC was not related to
its antioxidant properties or ability to increase intracellular glutathione levels but was instead dependent on ongoing transcription and seemed attributable to the action of NAC as a reducing agent. Here,
we investigate the mechanism by which NAC promotes neuronal survival.
We show that NAC activates the Ras-extracellular signal-regulated kinase (ERK) pathway in PC12 cells. Ras activation by NAC seems necessary for survival in that it is unable to sustain serum-deprived PC12 MM17-26 cells constitutively expressing a dominant-negative form
of Ras. Promotion of PC12 cell survival by NAC is totally blocked by
PD98059, an inhibitor of the ERK-activating MAP kinase/ERK kinase,
suggesting a required role for ERK activation in the NAC mechanism. In
contrast, LY294002 and wortmannin, inhibitors of phosphatidylinositol
3-kinase (PI3K) that partially block NGF-promoted PC12 cell survival,
have no effect on prevention of death by NAC. We hypothesized
previously that the ability of NAC to promote survival correlates with
its antiproliferative properties. However, although NAC does not
protect PC12 MM17-26 cells from loss of trophic support, it does
inhibit their capacity to synthesize DNA. Thus, the antiproliferative
effect of NAC does not require Ras activation, and inhibition of DNA
synthesis is insufficient to mediate NAC-promoted survival. These
findings highlight the role of Ras-ERK activation in the mechanism by
which NAC prevents neuronal death after loss of trophic support.
