pubmed:abstractText |
The cysteine protease CMS2MS2 from Carica candamarcensis latex has been shown to enhance proliferation of L929 fibroblast and to activate the extracellular signal-regulated protein kinase (ERK). In experiments with CMS2MS2 irreversibly inhibited by E-64, the proliferative effect on fibroblasts remains unaffected. ERK phosphorylation mediated by CMS2MS2 was abolished in the presence of PD 98059 or U0126, both MAPK cascade inhibitors. In addition, these inhibitors suppress the mitogenic activity of intact CMS2MS2 or CMS2MS2-E-64. Furthermore, ERK phosphorylation and the mitogenic effect are partially suppressed by a phospholipase C (PLC) inhibitor. These data suggest that the mitogenic effect of CMS2MS2 on fibroblasts is independent of its proteolytic activity, requires ERK phosphorylation, and involves activation of PLC.
