TP53 and non-small cell lung carcinoma: Again, similar as for NSCLC, miR-34a expression was significantly higher in TP53-wt than in TP53-mutated tumors (p = 0.0181; Additional file 2: Figure S2a), even with a small, but significant negative association of TP53 mRNA and miR-34a expression (p = 0.00057; R2 = 0.0395; data not shown).
