CDKN2B-AS1 and gastric cancer: Regulatory interactions between ANRIL and specific miRNAs have also been observed in many cancers, such as the interactions between ANRIL and both miR-125a and let-7a in CC and nasopharyngeal cancer(Hu et al. 2017; Wang et al. 2017; Zhang et al. 2018), or the ANRIL-miR-99a/miR-449a regulatory axis in gastric cancer(Zhang et al. 2014).
