In addition to a positive correlation between DDIT4 and PML mRNA expression in lung adenocarcinomas (Fig. 7B), PML and TAP1 showed a similar positive correlation (Spearman’s r = 0.445, p < 0.01, Fig. 7B) and no correlation between PML and BCL2 (Spearman’s r = 0.060, p = 0.365,Fig. 7B). Here, TAP1 is linked to lung adenocarcinoma.
