Descrição geral

Phorbol 12-myristate 13-acetate is a phorbol ester. It works as a tumor promoter and is involved in gene transcription, cell growth, differentiation, programmed cell death, immune pathway and receptor desensitization via protein kinase C (PKC) signaling pathways. Phorbol 12-myristate 13-acetate is also a model agent to study growth factors-, hormones-, and cytokines-mediated regulation of cellular growth and differentiation.


Phorbol 12-myristate 13-acetate has been used for the stimulation of various cells including spleen cells, quiescent lymphocytes and fetal thymocytes. It has also been used for the activation of PKC (protein kinase C) in cells.

Ações bioquímicas/fisiológicas
