Notably, high expression of CARM1 (Figure 6F; Cutoff value was 262; P < 0.01) or CCNE2 (Figure 6G; Cutoff value was 228; P < 0.01) was highly associated with shorter 10-year overall survival of NSCLC (adenocarcinoma) patients, implying the oncogenic roles of CARM1 and CCNE2 in promoting the progression of NSCLC. Here, CCNE2 is linked to adenocarcinoma.
