Pyruvate and Metabolic Flexibility: Illuminating a Path Toward Selective Cancer Therapies
2016
Dysregulated metabolism is an emerging hallmark of cancer, and there is abundant interest in developing therapies to selectively target these aberrant metabolic phenotypes. Sitting at the decision-point between mitochondrial carbohydrate oxidation and aerobic glycolysis (i.e., the ‘Warburg effect'), the synthesis and consumption of pyruvate is tightly controlled and is often differentially regulated in cancer cells. This review examines recent efforts toward understanding and targeting mitochondrial pyruvate metabolism, and addresses some of the successes, pitfalls, and significant challenges of metabolic therapy to date.
