Overexpression of lncRNA NBAT-1 inhibited tumor glycolysis. A. The protein levels of related metabolic enzymes (PKM2, HK-II, G-6-P and PFK1) were examined by Western blot assay of control cells and lncRNA NBAT-1 overexpression cells. B. Percentage of [U-13C] glucose to unlabeled glucose in control cells and lncRNA NBAT-1 overexpression cells starved without glucose overnight, followed by [U-13C] glucose addition. *P<0.05, **P<0.01. C. Medium lactate levels were detected in control cells and lncRNA NBAT-1 overexpression cells. *P<0.05, ***P<0.001. D. Medium glucose consumption was detected in control cells and lncRNA NBAT-1 overexpression cells. *P<0.05, **P<0.01.
