BMI1 and non-small cell lung carcinoma: Furthermore, knockdown of Bmi1 (Figure S1) inhibited both anchorage‐dependent (Figure 1C) and ‐independent cell growth (Figure 1D) in NCI‐H23, NCI‐H1299, and NCI‐H460 cells, suggesting that blocking Bmi1 expression reduced the tumourigenic properties of NSCLC cells in vitro.
