Anti-tumor effect of 5-aza-2'-deoxycytidine by inhibiting telomerase activity in hepatocellular carcinoma cells

Figure 3 Expression of telomerase reverse transcriptase protein in hepatocellular carcinoma cell lines SMMC-7721 (A) and HepG2 (B) during exposure to 5-aza-2’-deoxycitidine (1 μmol/L, 2 μmol/L or 4 μmol/L). Total proteins were extracted, and Western blotting analysis was performed. The same blot was reprobed for β-actin as a loading control; hTERT: Human telomerase reverse transcriptase.
