We found that knockdown of RB1CC1, DLL1, PRG4, PCLO, and NBPF10 increased, while knockdown of TAF1L, PREX2 and ATXN3 and upregulation of TP53 and MADCAM1 and KRTAP5-5 impaired the migration ability of GC cells, which suggested their potential roles in metastasis of GC (Supplementary Fig. 2). Here, PCLO is linked to gastric cancer.
