Tamoxifen-induced Rapid Death of MCF-7 Breast Cancer Cells is mediated via ERK Signaling and can be abrogated by Estrogen.
Tamoxifen (Tam) is widely used in chemotherapy of breast cancer. It inhibits proliferation and induces apoptosis of breast cancer cells by estrogen receptor (ER)-dependent modulation of gene expression. In addition, recent reports have shown that Tam also has nongenomic effects. We previously reported induction of a rapid mitochondrial death program in breast cancer cells at pharmacological concen
