1 Additionally, boldine, glaucine, and probucol, each at 50 microM, inhibited TPA-induced translocation of protein kinase C (PKC) to the particulate fraction of the cells, with concomitant inhibition of TPA-induced hyperphosphorylation of gap junctional connexin 43 (cx43) and TPA-induced internalisation of cx43 protein from the plasma membrane of the cells. boldine gap junction protein, alpha 1 Rattus norvegicus
