Dichloroacetate is an effective treatment for sarcoma models in vitro and in vivo

Background Sarcomas are cancers that arise from tissues of mesenchymal origin and there has been limited improvement in treatments over the last 30 years. The Warburg effect is a widespread metabolic phenotype of cancer, where glycolysis is favoured despite the presence of oxygen. Dichloroacetate (DCA) is a pyruvate dehydrogenase kinase (PDK) inhibitor in clinical use that can reverse the Warburg effect, inhibiting growth and enhancing apoptosis in a range of cancers. We have investigated its effectiveness against sarcoma cells in vitro and in vivo.
