MALAT1 and pachyonychia congenita: In addition to the above regulatory axis, there are many other lncRNA-mediated ceRNA regulatory networks that exert disparate and essential impacts on PC pathogenesis and development, like: THAP9-AS1/miR-484/YAP, MIR31HG/miR-193b, MALAT1/miR-217/KRAS axis regulate the growth and survival of tumor cells [113–115].
