WP1122 is a 2-deoxy-D-glucose prodrug in pre-clinical development for glioblastoma

The Warburg Effect is a universal feature of cancer; it describes the phenomenon whereby cancer cells preferentially use glucose for anaerobic glycolysis, as opposed to aerobic respiration via the Krebs Cycle. In order to meet the increased energy demands using a much less efficient process for ATP production, cancer cells take-up 20-times more glucose than wild-type cells. Continue reading

Lactate is another energy source for cancer cells

We have written previously about the Warburg Effect, the observation that cancer cells “bypass normal cellular respiration, that is, glucose converted to pyruvate through glycolysis, and the sequential oxidation of pyruvate through the Krebs Cycle in the mitochondria. Instead, tumor cells divert pyruvate to lactate dehydrogenase (LDH), which reduces pyruvate into lactate.” Continue reading
