SMARCA4 and non-small cell lung carcinoma: Although BRG1 mRNA was detected in all 47 cell lines evaluated, the level of expression in the NSCLC lines showed a wider variation range of 0.11–3.75-fold (Figure 1A, top panel, bar graph) compared to the relatively uniform expression (0.56–1.29-fold) in the immortalized and CST HBEC/HSAEC lines (Figure 1B, top panel).
