title: [The role of protein kinase C in tumor growth].
abstract: A review of recent papers dealing with the role of protein kinase C (PK C) in regulation of normal and tumour cell proliferation contains the data on the interaction of PK C with the tumour promoters and oncoproteins as well as the data which characterize changes of the PK C activity in tumour cells and during carcinogenesis. Probable mechanisms of the PK C influence on the functioning of the growth factors receptors are discussed. It is proposed that one of the PK C functions which is substantial for induction of the mitogenic signal is the polyamine synthesis stimulation. Participation of PK C in the tumour promotion may play a key role in multistep processes of the carcinogenesis.
