title: Altered cellular functions in a PC-12 cell clone chronically infected with retrovirus.
abstract: We characterized retrovirus-induced changes in PC-12 cell function and neuronal differentiation. PC-12 cells were infected with a neurotropic retrovirus (temperature-sensitive Moloney murine leukemia virus, mutant BA-1). We isolated a cell clone from this infected culture that displayed altered response to nerve growth factor; increased choline acetyltransferase activity; and decreased basal and nerve growth factor-stimulated acetylcholinesterase activity. In addition, Kirsten murine sarcoma virus infection of and subsequent expression of the v-ras oncogene in PC-12 cells induced neurite extension, enhanced choline acetyltransferase activity, and limited the growth potential of the infected cells.
