To assess EHMT1 expression levels, we performed tissue‐wide expression profile analysis of EHMT1 in the Gene Expression Database of Normal and Tumor Tissues (GENT) (http://gent2.appex.kr/gent2/) and showed that the expression of EHMT1 was higher in several types of cancers than in normal tissues (Fig. S1). The gene discussed is EHMT1; the disease is cancer.
