Protein Kinase C delta Supports Survival of MDA-MB-231 Breast Cancer Cells by Suppressing the ERK1/2 Pathway
Mechanisms that mediate apoptosis resistance are attractive therapeutic targets for cancer. Protein kinase C delta (PKC delta) is considered a pro-apoptotic factor in many cell types. In breast cancer, however, it has shown both pro-survival and pro-apoptotic effects. Here, we report for the first time that down-regulation of PKC delta per se leads to apoptosis of MDA-MB-231 cells. Inhibition of M
