Table 5. Seven selected genes were analyzed in four cell lines by RT-PCR.
| Genes | HepG2 | 7402 | 97L | 97H |
| WNK2 | 151 | 0.68 | 1.38 | 0.086 |
| EMILIN2 | 9.4 | 0.66 | 0.28 | 48.8 |
| TLX3 | 6.8 | 1.3 | 6.8 | 8.02 |
| TM6SF1 | 5.18 | 352.8 | 4.9 | (-) |
| TRIM58 | 2.55 | 0.3 | 0.03 | 107.8 |
| HIST1H4F | 3.2 | 0.64 | 0.004 | 100.7 |
| GRASP | 5.66 | 0.65 | 0.05 | (-) |
The expression of the selected genes after treated with 5-aza-dc was summarized in the table 5 and before treatment was used as control. The relative expression rate = the expression of gene after treatment/the expression of gene before treatment.
