Knockdown of miR-27b-3p inhibited cell proliferation in AGS cells. (A) quantified-PCR (Q-PCR) analyzed the expression of miR-27b-3p in GES-1, AGS, BT474, MGC-803, and N87. (B) AGS cells were transfected by negative control (NC), miR-27b-3p agomir, or miR-27b-3p antagomir, and the cell viability was assessed by MTT. All the experiments were carried out in triplicate. *P<0.05, **P<0.01, ***P<0.001.
