EGFR and pachyonychia congenita: In addition, it has been proven that XIST/miR-133a/EGFR (99), XIST/miR-34a-5p (98), and XIST/miR-137/Notch1 (100) ceRNA axes also played important roles in PC cell growth and survival regulation, while XIST/miR-429/ZEB1 (101) and XIST/miR-141-3p/TGF-β2 (102) ceRNA axes contributed to PC cell migration and invasion.
