Beyond Warburg: LDHA activates RAC for tumour growth

The physiological role of aerobic glycolysis (also known as the Warburg effect), which is observed in many tumours, is still not fully understood. The finding that lactate dehydrogenase A (LDHA) activates RAC1 in breast cancer sheds new light on this persistently enigmatic aspect of cancer metabolism.
