CCK-8 assay of cell proliferation. (A) Reverse transcription-quantitative polymerase chain reaction analysis of miR-421 expression in MKN28/MKN74 cells following transfection with miR-421 inhibitor. (B) A CCK-8 assay was performed in MKN28/MKN74 cells transfected with miR-421 inhibitor or NC inhibitor. The optical density of each well was measured at 450 nm at the indicated time-points. *P<0.05 vs. NC. CCK-8, cell counting kit-8; miR, microRNA; NC, negative control; OD, optical density; h, hours.
