The circ-001971/miR-29c-3p axis modulates the tube formation capacity of HUVECs (a-b) HCT116 and SW620 cells were cotransfected with miR-29c-3p inhibitor and si-circ-001971, and the protein levels of VEGFA were determined. c-d HUVECs were cultured in miR-29c-3p inhibitor and si-circ-001971 transfected SW620 cell conditioned medium (CM) and assayed for tube formation capacity. *P < 0.05, **P < 0.01, compared to si-NC + inhibitor-NC group; ##P < 0.01, compared to si-circ-001971 + inhibitor-NC group
