Examples include miR‐30c‐2‐3p in breast cancer (Shukla et al., 2015), miR‐218 in hepatocellular carcinoma (Yang et al., 2016), CXCL14 in colorectal carcinoma (Zeng et al., 2013), and SERPINH1 in clear cell renal cell carcinoma (Qi et al., 2018). This evidence concerns the gene CXCL14 and clear cell renal carcinoma.
