(A) Neurones were transfected with control or miR-143 inhibitor for 48 h, followed by the detection of miR-143 expressions by qRT-PCR. (B) Neurones were transfected with control or miR-143 inhibitor for 48 h, cells were subjected to OGD for 48 h, the expressions of miR-143 were measured by qRT-PCR. (C) Neurones were transfected with control or miR-143 inhibitor for 48 h, cells were subjected to OGD for 48 h then the cell viabilities were measured by MTT assay. (D) Activities of Caspase-3 were measured in neurones with the indicated treatments. Data are representative of three independent experiments. Mean ± S.E.M. *, P<0.05; **, P<0.01; ***, P<0.001.
