Figure 4. miR-1238 suppresses NSCLC cell proliferation and metastasis (**P < 0.01). (A) qRT-PCR detected miR-1238 expression in NSCLC cell lines. (B) CCK-8 assay was performed to investigate cell proliferation ability. (C) Colony formation assay was conducted to reveal cell colony-forming ability. (D) Barplot drawn by ImageJ. (E) Transwell assay was performed to detect cell metastasis. (F) Barplot drawn by ImageJ.
