Exploiting lipotoxicity for the treatment of liver cancer

Abstract

Metabolic alterations occur frequently in solid tumours, but metabolic cancer therapies are limited by the complexity and plasticity of metabolic networks. We could recently show that activation of the liver X receptor alpha (LXRα) and inhibition of a Raf-1-SCD1 protein complex induces an intracellular accumulation of saturated free fatty acids leading to lethal lipotoxicity in tumour cells and allows for an efficient treatment of liver carcinomas.
