Ações bioquímicas/fisiológicas

Phorbol 12-myristate 13-acetate is a potent tumor promoter and activates protein kinase C in vivo and in vitro. It is a phorbol ester that is associated with many cellular responses including gene transcription, cell division and differentiation, apoptosis and immune response. It is also involved in protein kinase C (PKC) mediated receptor desensitization. Phorbol 12-myristate 13-acetate induces PKC localization from the cytosol, enabling the enzyme association with the cell membrane.
Potent tumor promoter; activates protein kinase C in vivo and in vitro.
