(a) mRNA levels of PKM2 and HK2. (b) PKM2 protein expression in LX2 cells was detected by immunofluorescence. (c) mRNA levels of αSMA and COL1α1. (d) αSMA protein expression in LX2 cells was examined by immunofluorescence. Data are shown as the mean ± SD (n = 3) of one representative experiment; *P < 0.05, **P < 0.01 vs. control group; #P < 0.05, ##P < 0.01 vs. TGF-β1-stimulated group.
