Several lines of CHO cells stably overexpressing protein kinase C (PKC) subspecies to various extents were established by the DNA-mediated transfer. Upon treatment with phorbol 12-myristate 13-acetate, the growth of the cells expressing the PKC-delta subspecies was markedly inhibited, whereas cell lines expressing PKC-alpha, PKC-beta II, and PKC-zeta subspecies were not significantly affected. Flow cytometric analysis indicated that all cell lines overexpressing PKC-delta subspecies accumulated in G2/M phase in response to phorbol 12-myristate 13-acetate. In these arrested cells, dikaryons were predominant, implying that phorbol ester-induced inhibition of cell division is specific to telophase. These results suggest PKC-delta subspecies may play a role in the normal cell cycle progression. IMAGES:
