Figure Lengend Snippet: DNMT3A modulated IAPs expression to suppress tyrosine kinase inhibitors (TKIs)-induced cell apoptosis. A. The correlation analysis between DNMT3A expression and BIRCs (BIRC1-7) expression in 230 patients with non-small cell lung cancer (NSCLC) from the TCGA database. B. Heatmap of BIRCs (BIRC1-7) expression at the mRNA level in P1 and P2 cells. C. Heatmap of BIRCs (BIRC1-7) expression at the mRNA level in vector and DNMT3A overexpressed NCI-H3255 cells. D. Western blotting of c-IPA1 in P1, P2, vector and DNMT3A overexpressed NCI-H3255 cells. E. P1 and P2 cells were treated with SM-1295 (20 nM), erlotinib (2 μM), afatinib (5 μM) or in combination for 48 h. Then, cell apoptosis was assessed. F. Vector and DNMT3A overexpressed NCI-H3255 cells were treated with SM-1295 (20 nM), erlotinib (2 μM), afatinib (5 μM) or in combination for 48 h and then cell apoptosis was assessed. G. Representative images of c-IAP1 immunohistochemical staining in NSCLC tissues from recurrent and non-recurrent patients (n = 30, scale bar = 100 μm).
