Other enriched functional categories included cell cycle (AIF1, BCAT1, RAD54L, and STK6), regulation of transcription (ARID3A, DMAP1, and ZNF239), cell proliferation and apoptosis (CROC4, BIRC2, PLK1, and PORMIN), adhesion (ICAM1), and structural proteins related to tumor progression (KRT8 and KRT18; Table 2 and Additional data file 2). Here, PLK1 is linked to neoplasm.
