Many tumors metabolise the majority of the glucose that they take up through glycolysis even in the presence of an adequate oxygen supply. Lactate dehydrogenase A (LDH-A) is the critical enzyme that catalyses the transformation of pyruvate to lactate. We demonstrate that LDH-A reduction can suppress the tumorigenicity of intestinal-type gastric cancer (ITGC) cells by downregulating Oct4 both in vitro and in vivo. A statistical analysis of 661 ITGC specimens showed a significant correlation between LDH-A and Oct4 expression. Moreover, patients with low LDH-A/negative Oct4 expression exhibited better overall survival than patients with other combinations. We conclude that the close correlation of LDH-A and Oct4 may offer a promising therapeutic strategy for ITGC. (C) 2012 Elsevier Ireland Ltd. All rights reserved.
