For example, CiRS-7/Cdr1as is a miR sponge that is upregulated and involved in the regulation of ESCC [77], GC [78], CRC [79], and HCC [80] by different pathways, which suggests that the downregulation of ciRS-7/cdr1as expression might provide an effective treatment method. This evidence concerns the gene LINC00632 and gastric cancer.
