Expression of protein kinase C isoenzymes in benign hyperplasia and carcinoma of prostate.

Protein kinase C family consists of 11 isoforms, classified into 3 categories according to their structure and mechanisms of activation. These isoenzymes are involved in processes, which maintain intracellular homeostasis. Alterations in activity, amount or distribution of protein kinase C (PKC) isoenzymes may cause cellular proliferation or induce apoptosis.
