Role of aerobic glycolysis in genetically engineered mouse models of cancer.
The propensity of cancer cells to convert high levels of glucose to lactate through aerobic glycolysis has been intensively studied in vitro, and is now understood to be a metabolic adaptation that shunts glucose carbons toward building blocks for the growing cell, as well as producing ATP. Much less is known, however, about the role of aerobic glycolysis and glycolytic enzymes in vivo. A paper in Cancer and Metabolism now documents aerobic glycolysis in the proliferating neural progenitors that form the cerebellum in normal newborn mice, as well as in medulloblastoma tumors derived from these cells in transgenic mice. Hexokinase II is demonstrated to be an essential driver of the observed aerobic glycolysis and the malignancy of the tumors. See research article: http://www.cancerandmetabolism.com/content/1/1/2.
