LDH
In normal tissues, lactate generation is limited to anaerobic conditions where oxygen levels are low. In contrast, cancer cells preferentially convert glucose into lactate through glycolysis, even under normal oxygen concentrations, a phenomenon termed “aerobic glycolysis” or the Warburg effect. Anti-glycolytic therapeutic approaches against cancer have been (re-)evaluated, in consideration of the dependence that cancer cells have on a high glycolytic rate[1]. In particular, human LDH-A (or LDH-5; EC 1.1.1.27), a key glycolytic enzyme that catalyzes the formation of lactate from pyruvate and is frequently upregulated in clinical tumors, is currently being considered as a strategic target for the blockage of glycolysis. Since humans missing the LDH-A enzyme (as a hereditary disease), are healthy, it has been hypothesized that inhibition of LDH-A as an anticancer strategy should give no significant on-target side effects [2], [3].
