Abstract
Cancer cells can develop resistance to endocrine therapies, such as Tamoxifen, through acquisition of the Y537S mutation. Cells transfected with the Y537S mutation showed significant increases in mitochondrial mass and membrane potential, consistent with an increase in mitochondrial biogenesis. Certain biomarkers are identified that have prognostic value of endocrine therapy resistance. The mechanism resulting in this resistance, however, leaves these treatment-resistant cells vulnerable to therapeutics that inhibit mitochondrial biogenesis. Numerous mitochondrial biogenesis inhibitors are disclosed, as well as methods for reducing or eliminating endocrine treatment resistance, improving the effectiveness of an endocrine therapy, and for treating cancer.
