SMARCA4 and non-small cell lung carcinoma: Furthermore, we found a strong correlation (r = 0.8; p = 0.001) between SMARCA2 and CCND1 mRNA expression in SMARCA4-mutated LUAD tumors (Fig. 3g) but not in the non-selected TCGA cohort (Supplementary Fig. 9), supporting the role of SMARCA2 in regulating CCND1 expression when SMARCA4 is lost in NSCLC.
