SOX4 and liver cancer: LncRNAs can regulate tumorigenesis through multiple molecular mechanisms, such as a novel ceRNA model, for instance, STAT3-mediated acted as a ceRNA to upregulate lncRNA HOXD-AS1 by regulating SOX4 to facilitate liver cancer metastasis [26], lncRNA XLOC_006390 promotes cervical cancer progress as a ceRNA sponge miR-331-3p and miR-338-3p [27].
