So cancer or cancer cells are these abnormal cells that essentially grow very quickly and very rapidly. So they divide very quickly. And what that means is they have to have a very high supply of ATP to actually live and continue dividing and growing. And cancer cells to basically determine that they have these blood vessels to basically ensure that they have these blood vessels next to them at all times so that they can receive the supply of glucose and then use that glucose in the highly effective process of glycolysis to produce those ATP molecules which allow them to actually grow and divide quickly. They also use this same mechanism. They release the Hypoxiainducing transcription factor that stimulates not only the expression of these enzymes and glucose transporters but also stimulates the growth of those blood vessels which can permeate into that tumor and around that tumor and that ensures that the tumor actually survives and those cancer cells actually survive and grow.
