Nerve growth factor (NGF) causes PC12 cells to cease division and undergo sympathetic neuron-like differentiation, including neurite outgrowth. We have tested whether differentiation and division share overlapping control mechanisms in these cells. To do this, we have perturbed the activity of proteins known to participate in cell-cycle regulation by introducing the E1A oncogene or its mutant forms via microinjection into PC12 cells. The E1A protein binds to several putative cell cycle control proteins, including p105Rb (the product of the retinoblastoma susceptibility gene), as well as others of unknown function such as p130, p107, and p300. Similar to previous results, we find that wild-type E1A abrogates NGF-induced neurite extension. However, NGF does cause neurite outgrowth in the presence of E1A mutants known to have greatly reduced binding to either p105Rb and p130 or p300. Our experiments suggest that p105Rb, p130, and p300 may participate either in E1A-mediated inhibition of differentiation or in the NGF signal transduction pathway. We also report here that NGF affects phosphorylation of p105Rb, suggesting that Rb mediates at least some of NGF's effects. Our results raise the possibility that putative cell-cycle control proteins may participate not only in NGF-induced cessation of division but also in differentiation.
