Figure 5

DNMTs RNA expression in human oral cancer cell lines. The measurement of DNMTs expression levels by real-time PCR was showed in (a), (b), and (c), respectively. (a) The Dnmt1 expression was not changed in all human oral cancer cell lines. (b) and (c) TW2.6 and Ca922 were higher expression in Dnmt3a and Dnmt3b than others. The figures shown are the mean of three experiments where all of the samples were analyzed in triplicate. The start sign showed the statistically significant ().
