As shown in Figure 3D, A549/PTX CD133+ cells treated with miR-128 showed significantly reduced cell growth and lower levels of BMI-1 and CD133 compared with the cells treated with miR-NC, indicating that miR-128 inhibits cell growth and reduces the levels of oncogenic proteins and CSC markers in PTX-resistant lung cancer stem cells. This evidence concerns the gene BMI1 and lung carcinoma.
