Knockdown of CD133 and VEGF abolished the promoting effects of anti-miR-377 on cancer stemness and angiogenesis. (a) The increased expression levels of CD133 and VEGF in miR-377-knockdown ESCC cells were inhibited by the siRNAs against CD133 and VEGF, respectively. (b) The miR-377-knockdown ESCC cells transfected with si-CON or two different siRNAs against CD133 were compared for ability to form spheres over serial passages. (c) Effects of conditioned medium (CM) from ESCC cells with the indicated manipulation of miR-377 and VEGF expressions on the tube-formation activity of HUVECs. Bars, s.d.; *P<0.05; **P<0.01.
