LINC01111 and pachyonychia congenita: The results of the CCK-8 assays and colony formation assays revealed that the overexpression of LINC01111 significantly inhibited the proliferative capacity of PC cells compared with that of negative control (NControl) cells, while the knockdown of LINC01111 enhanced the proliferation of PC cells relative to that of NControl cells (Fig. 2b, c).
