title: Down-regulation of cyclin F levels during nerve growth factor-induced differentiation of PC12 cells.
abstract: Treatment with nerve growth factor (NGF) produces a marked decrease of cyclin F levels in PC12EY cells. This decrease is prevented by the simultaneous addition of K-252a. A smaller decrease is observed when the cells are treated with fibroblast growth factor, but the addition of epidermal growth factor has no comparable effect. Time course studies show that the decrease in cyclin F precedes the changes produced by NGF in the distribution of cells within the cell cycle. The data suggest that cyclin F is involved in NGF-mediated cell cycle events during the differentiation of PC12EY cells.
