Fig. 4From: MicroRNA-338-3p suppresses cell proliferation and induces apoptosis of non-small-cell lung cancer by targeting sphingosine kinase 2miR-338-3p promotes apoptosis. FITC fluorescein isothiocyanate, PI propidium iodide, NC cells transfected with negative control. a At 48 h after transfection with miR-338-3p or NC, A549 cells or H1299 cells was collected for analysis of apoptosis. Flow cytometry was used to measure apoptosis after 2 days in A549 or H1299 cells transfected with miR-338-3p or NC. b Percent of NSCLC apoptosis was calculated using TUNEL staining. Apoptosis of A549 or H1299 cells transfected with miR-338-3p or NC measured after 2 daysBack to article page
