“Our data showed that ERK1/2 activation depended on PKC activation since: … (a pan-PKC inhibitor) blocked docetaxel-induced ERK1/2 phosphorylation ii) docetaxel increased PKC … 30% and phosphatidic acid level by 1.6-fold iii) inhibition of PKCε and … by siRNA resulted in reduced phosphorylated ERK1/2 levels.”
