[Even the Warburg effect can be oxidized: metabolic cooperation and tumor development].

During tumor development, malignant cells rewire their metabolism to meet the biosynthetic needs required to increase their biomass and to overcome their microenvironment constraints. The sustained activation of aerobic glycolysis, also called Warburg effect, is one of these adaptative mechanisms. The progresses in this area of research have revealed the flexibility of cancer cells that alternate between glycolytic and oxidative metabolism to cope with their conditions of development while sharing their energetic resources. In this survey, we review these recent breakthroughs and discuss a model that likens tumor to an evolutive metabolic ecosystem. We further emphasize the ensuing therapeutic applications that target metabolic weaknesses of neoplastic cells.
