For example, circ_001422 was able to inhibit the expression of miR‐195‐5p, which in turn promotes the kinase insert domain receptor (KDR)/mTOR signaling pathway and facilitates endothelial cell migration and angiogenesis, suggesting that circ_001422 has a role as a biomarker in the diagnosis of CRC.706. Here, KDR is linked to colorectal carcinoma.
