Although KMTs and KDMs were not strongly induced by EBV infection, the expression of several KMTs was moderately increased, with those of SUV39H2, DOTIL, and EZH2 genes increasing 3.6-, 4.5-, and 3.6-fold, respectively (Fig. 1A, KMT group). The gene discussed is SUV39H2; the disease is Epstein-Barr virus infection.
