Abstract

The effects of nerve growth factor (NGF) and two analogs of cAMP have been studied in the PC12 line of rat pheochromocytoma cells. We have used two-dimensional gel electrophoresis to detect more than 800 proteins from control and NGF-treated cells. Of these proteins, none were qualitatively repressed in response to NGF, and no new proteins appeared after NGF treatment. Visual inspection of the gels showed that approximately 5% of the proteins were detectably increased or decreased in rate of synthesis by NGF, and each of these changes was mimicked by both cAMP analogs. The two-dimensional gel data were further analyzed by a computerized scanning system. This analysis has revealed many significant changes that are smaller than those detected by eye. Approximately 25 to 30% of the proteins analyzed were found to be altered in rate of synthesis by 30% or more. Statistical analysis has shown that the response to NGF and the response to dibutyryl cAMP are highly correlated, even down to changes as small as 30%. No proteins were found to be significantly altered by both dibutyryl cAMP and 8-bromo cAMP, but not by NGF. These results show that NGF causes only quantitative modulations of protein synthesis in PC12 cells, and these data strongly suggest that the response of PC12 cells to NGF is mediated by cAMP.
