Duan et al. (2020) reported that ZFAS1 promotes the development of hepatocellular carcinoma through the miR-624/MDK/ERK/JNK/p38 signaling pathway. Guo et al. (2019) found that ZFAS1 can promote the migration of hepatocellular carcinoma cells by regulating the production of reactive oxygen species. Zhou, Zhou & Feng (2019) reported that ZFAS1 promotes the proliferation of hepatocellular carcinoma by epigenetically inhibiting miR-193a-3p. This evidence concerns the gene MDK and hepatocellular carcinoma.
