A Expression of miR-1270 in BEAS-2B cells, A549 cells and SK-MES-1 cells; B the expression of miR-1270 was increased after circ_0072088 knockdown in A549 cells; C The expression of miR-1270 was increased after circ_0072088 knockdown in SK-MES-1 cells; D Expression of miR-1270 in A549 cells after transfection of NC and mimics; E Expression of miR-1270 in SK-MES-1 cells after transfection of NC and mimics; F Overexpression of miR-1270 inhibited cell proliferation in A549 cells; G Overexpression of miR-1270 inhibited cell proliferation in SK-MES-1 cells; H Overexpression of miR-1270 inhibited cell migration in A549 cells; I Overexpression of miR-1270 inhibited cell migration in SK-MES-1 cells; J Overexpression of miR-1270 promoted apoptosis of A549 cells; K Overexpression of miR-1270 promoted apoptosis of SK-MES-1 cells
