Suppression of miR-147b contributed to H37Rv-infected macrophage viability and migration in tuberculosis in vitro.

•MiR-147b expression was higher and cell viability decreased in H32Rv-THP-1 cells.•Cell viability was shown higher after miR-147b downregulation.•RT-qPCR found C11orf87 expression was lower in the H32Rv-THP-1 cells.•Moreover, when H32Rv-THP-1 cells were co-transfected with miR-147b inhibitor and si-C11orf87, cell viability, migration and EMT.•Activation of Pi3K/AKT pathway was partially reversed compared with mere downregulation of miR-147b.
