Moreover, in the quantitative methylation-specific PCR (Q-MSP) analysis, the normalized methylation value (NMV) for the TET1 and TET3 gene promoters tended to be higher in cancer cells than in normal tonsil samples and normal cell lines (P < 0.001 and P = 0.002, respectively) (Figure 1D and 1F). The gene discussed is TET3; the disease is cancer.
