Abstract

Common molecular changes in cancer cells are high carbon flux through the glycolytic pathway and overexpression of fatty acid synthase, a key lipogenic enzyme. Since glycerol 3-phosphate dehydrogenase creates a link between carbohydrates and the lipid metabolism, we have investigated the activity of glycerol 3-phosphate dehydrogenase and various lipogenic enzymes in human bladder cancer.

The data presented in this paper indicate that glycerol 3-phosphate dehydrogenase activity in human bladder cancer is significantly higher compared to adjacent non-neoplastic tissue, serving as normal control bladder tissue. Increased glycerol 3-phosphate dehydrogenase activity is accompanied by increased enzyme activity, either directly (fatty acid synthase) or indirectly (through ATP-citrate lyase, glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase and citrate synthase) involved in fatty acid synthesis. Coordinated upregulation of glycerol 3-phosphate dehydrogenase and lipogenic enzymes activities in human bladder cancer suggests that glycerol 3-phosphate dehydrogenase supplies glycerol 3-phosphate for lipid biosynthesis.
