Figure 2 The effect of NR2F1-AS1 on hypoxia-induced glycolysis and migration in HCC. NR2F1-AS1 expression (A and B), glucose uptake (C and D), lactate production (E and F), ATP level (G and H), HK2 protein level (I and J) and migration (K and L) were detected in Hep3B and Huh7 cells with transfection of si-con, si-NR2F1-AS1 #1 or #2 under hypoxic condition via qRT-PCR, specific kit, Western blot and transwell assay. NC: non-transfected group; Normal: normoxic condition. *P<0.05 versus normal group, #P<0.05 versus si-con group.
