We further knocked down ASXL3 within two other SCLC cell lines, NCI-H748 and NCI-H1882, with ASXL3-specific shRNAs (Additional file 2: Figure S5B) and confirmed the expression change of the indicated genes by real-time PCR (Additional file 2: Figure S5C). Here, ASXL3 is linked to small cell lung carcinoma.
