Protein Kinase C: An Attractive Target for Cancer Therapy

Abstract: Apoptosis plays an important role during all stages of carcinogenesis and the development of chemoresistance in tumor cells may be due to their selective defects in the intracellular signaling proteins, central to apoptotic pathways. Consequently, many studies have focused on rendering the chemotherapy more effective in order to prevent chemoresistance and pre-clinical and clinical data has suggested that protein kinase C (PKC) may represent an attractive target for cancer therapy. Therefore, a complete unders… Show more

“…The PKC family consists of phospholipid-dependent serine/threonine-specific protein kinases which mediate various cellular functions including proliferation, apoptosis and differentiation (87). The deregulation of PKC signalling has been implicated in cancer, including breast cancer where it promotes tumourigenesis by modulating cell proliferation, migration, apoptosis and survival (87).…”

“…The deregulation of PKC signalling has been implicated in cancer, including breast cancer where it promotes tumourigenesis by modulating cell proliferation, migration, apoptosis and survival (87). Many studies which have investigated the role of the PKC pathway have employed the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA, also called PMA) which activates PKC isoforms by translocating them to specific cellular compartments (87). Mowla et al showed that in prostate epithelial and lung fibroblast cells, PMA, increased TBX3 mRNA and protein in a PKC-dependent manner (64).…”

“…As PKCs podem atuar tanto na oncogênese quanto na supressão do tumor através de cascatas de fosforilação de proteínas e há evidências de expressão aberrante em diversas linhagens tumorais de isoformas da enzima (tabela 2) (TOTOŃ et al, 2011;BOSCO et al, 2011). Este dado, entretanto, deve ser interpretado com cuidado uma vez que o mesmo isotipo regula, de maneira sutil, diversos caminhos bioquímicos envolvidos na transformação celular (MARENGO et al, 2011). A PKCα, por exemplo, pode atual como um promotor ou supressor de tumores, uma vez que sua expressão pode estar aumentada ou diminuída em diversos cânceres (MARENGO et al, 2011).…”
