Effect of PKC-zeta mediating Ang II- stimulated activation of CCDPK on rat cardiac fibroblast proliferation.

AIM: To investigate whether the effect of angiotensin (Ang) II or epidermal growth factor (EGF) on cardiac fibroblast proliferation involved in activation of extracellular signal-regulated kinase (ERK) 1/2 or Ca(2+)-calmodulin dependent protein kinase(CCDPK) mediated by protein kinase C (PKC)-zeta. METHODS: Relative activity of CCDPK was measured by Western blotting. DNA synthesis was assayed by [3H]thymidine incorporation. RESULTS: PDBU caused no decrease in Ang II- and 10% FCS- stimulated CCDPK activity and DNA synthesis. In contrary, 65% or 75% EGF- or tetradecanoylphorbol acetate (TDPA, formally called PMA)--stimulated CCDPK activity and 38% or 42% [3H]thymidine incorporation treated by PDBU were inhibited, respectively. Meanwhile 70% and 72% CCDPK activities induced by Ang II and EGF were inhibited by PD 98059, respectively. CONCLUSION: PKC-zeta mediated Ang II- induced activation of CCDPK and cardiac fibroblast proliferation.[1]
