Figure 1.

Expression of galactokinase 1, galactokinase 2 and ornithine carbamoyltransferase in various hepatocellular carcinoma and normal liver cell lines. Expression levels of (A) galactokinase 1, (B) galactokinase 2 and (C) ornithine carbamoyltransferase were analyzed by reverse transcription-quantitative polymerase chain reaction. Lanes: 1 HLE; 2, HLF; 3, PLC/PRL/5; 4, Hep3B; 5, HepG2; 6, human fetal liver; 7, human adult liver. Graphs represent the relative expression levels (REL) normalized against that of adult liver. Error bars indicate standard deviation; n=3.
