From: NLK functions to maintain proliferation and stemness of NSCLC and is a target of metformin
Effects of metformin treatment on cell cycles of NSCLC and immortalized noncancerous human bronchial epithelial cells. Cell cycle of PBS and metformin-treated A549 (a), SK-MES-1 (c), and BEAS-2B (e) cells were measured by flow cytometric analysis. Bar graph showing quantification results of A549 (b), SK-MES-1 (d), and BEAS-2B (f) cells in different phases of cell cycle. **p < 0.01
