The small molecule C-6 is selectively cytotoxic against breast cancer cells and its biological action is characterized by mitochondrial defects and endoplasmic reticulum stress
2014
Introduction
The establishment of drug resistance following treatment with chemotherapeutics is strongly associated with poor clinical outcome in patients, and drugs that target chemoresistant tumors have the potential to increase patient survival. In an effort to identify biological pathways of chemoresistant breast cancers that can be targeted therapeutically, a small molecule screen utilizing metastatic patient-derived breast cancer cells was conducted; from this previous report, the cytotoxic small molecule, C-6, was identified for its ability to selectively kill aggressive breast cancer cells in a caspase-independent manner. Here, we describe the cellular and molecular pathways induced following C-6 treatment in both normal and breast cancer cell lines.
