Expression of SOX9 was elevated in NSCLC cell lines. A and B. Expression analysis of SOX9 protein and mRNA in normal human pneumonocyte (NLE) and NSCLC cell lines (SK-MES-1, NCI-H460, NCI-H358, PAa, NCI-H596, NCI-H1650, NCI-H1975) by Western blotting (A) and real-time RT-PCR (B). Protein expression levels were normalized with β-actin mRNA expression levels were normalized for GAPDH. Bars, SD from three independent experiments.
