Bai et al. (2019) found DANCR could activate EMT and act as a ceRNA to competitively bind to miR-138. And then, Sox4, a vital regulator involving tumor growth and metastasis, was regulated. In addition to miR-138, many other miRNAs have been verified as sponge targets for DANCR (Lu Q.C. et al., 2018; Wang and Jiang, 2018; Zhen et al., 2018; Chen Y.R. et al., 2020; Yu et al., 2020; Huang et al., 2021). Another study by Guo L. et al. (2019) showed that DANCR facilitated carcinogenesis by epigenetically silencing p21 expression via binding to EZH2. This evidence concerns the gene DANCR and neoplasm.
