ABSTRACT
We examined the effects of diet nutrients on xenotransplanted leukemia cells, THP-1 or NB4. THP-1 tumors showed more growth when fed with high fat diet, while NB4 tumors grew more with high carbohydrate diet. Then, administration of 2-deoxyglucose (a glycolysis inhibitor) showed a significant antitumor effect on both tumors: NB4 tumor showed large necrotic areas, while THP-1 tumor did not, but had augmented expression of enzymes for fatty acid oxidation. 2-Deoxyglucose inhibited the growth of NB4 by cell death because main energy producing pathway (glycolysis) was abolished, while 2-deoxyglucose slowed the growth of THP-1 by shifting energy metabolism to fatty acid ß-oxidation.
