Correlation between PKM2 expression and SDC2 expression in HC cases. QBC939 cells were transiently transfected with control shRNA or PKM2 shRNA. a and b, the expression of several genes associated with NI and metastasis was measured using reverse transcription-polymerase chain reaction (a), and the level of PKM2 and SDC2 expression was determined using Western blotting (b). GAPDH, glyceraldehyde-3-phosphate dehydrogenase. c, graphical representation demonstrating a significant correlation between PKM2 expression and SDC2 expression in human HC tissues. d, co-localization of PKM2 and SDC2 in the consecutive sections of HC tissue. e, co-localization of PKM2 and SDC2 in the consecutive sections of HC tissue with NI.
