Considering both higher fold change of differential expression in MLN compared to NM and higher degree in lncRNA-mRNA co-expression network in MLN, 10 candidate lncRNAs were further selected and considered as the most key CRC metastasis-associated lncRNAs, including NONHSAT058538 (LINC-ANKRD30B-2), NONHSAT070749 (LINC-RTN4-2), NONHSAT137607 (FTX), NONHSAT027575 (LINC-AMN1-2), NONHSAT024787 (LINC-BLID-5), NONHSAT037814 (LINC-DLST-2), NONHSAT068481 (LINC-FAM110C-1), NONHSAT096913 (LINC-RCHY1-4), NONHSAT031619 (LINC-DNAH10OS-4), NONHSAT011934 (WAC-AS1). The gene discussed is FTX; the disease is colorectal carcinoma.
