CYTOR and non-small cell lung carcinoma: Chen et al found that lncRNA‐UICLM promote metastasis of CRC by acting as a ceRNA of miR‐215.29 Previous studies in our group found that lncRNA UCA1 and LINC00152 both function as ceRNAs to promote CRC cell proliferation and chemoresistance.15, 16 SNHG15 has already been confirmed to promote CDK14 expression by sponging miR‐486 in NSCLC.30 It could also promote breast cancer proliferation and metastasis through binding with miR‐211‐3p.21 These suggest that ceRNA is one of the most important mechanisms of SNHG15 in cancer.
