Figure 6. SNHG3 sequesters miR-139-5p and thereby regulates MYB expression. (A, B) AGS and MGC-803 cell proliferation was assessed via CCK-8 assay following pcDNA3.1-SNHG3, miR-139-5p mimic, and pcDNA3.1SNHG3+miR-139-5p mimic transfection. *P<0.01 vs. the pcDNA3.1-NC group. (C–F) Cell cycle progression in AGS and MGC-803 cells transfected as in (A, B) was assessed via flow cytometry. (G) MYB protein levels in AGS and MGC-803 cells transfected as in (A, B) were measured.
