BAD-interacting proteins in breast cancer cells

  • Author / Creator

  • Taxane chemotherapy is widely used in the treatment of breast cancer. Despite its widespread clinical use, the molecular mechanisms of paclitaxel induced apoptosis remain unclear. Our laboratory has identified an important role for the BH3-only protein, BAD, in the paclitaxel induced cell death pathway of breast cancer cells. Furthermore, BAD expression correlates with sensitivity to taxanes in vitro and in clinical studies. While BAD is a well characterized pro-apoptotic member of the BCL-2 family, our studies demonstrate a novel, non-apoptotic role for BAD in paclitaxel-induced cell death. Specifically, this work suggests a role for BAD in cell cycle progression or diminished apoptotic signaling, consistent with data from the laboratory documenting pro-growth activity of BAD. We screened for BAD interacting proteins to improve our understanding of BAD molecular dynamics and identify protein partners that may contribute to BAD pro-growth activity. BAD interactions with BCL-XL and 14-3-3 protein isoforms were examined.
