As a ceRNA, GAS5 interferes with the action of several miRNAs, including miR-21 [28], miR-23 [29], miR-32-5p [30], miR-128-3p [31,32], miR-196a-5p [33], miR-223-3p [34], and miR-378a-5p [35], and inhibits the ability of miRNAs to regulate their target genes, that can lead to cancer progression. This evidence concerns the gene GAS5 and cancer.
