AFAP1 and colorectal carcinoma: Other lncRNAs such as long non-coding RNA-activated by TGF-β (lncRNA-ATB) [154], actin filament associated protein 1 antisense RNA1 (AFAP1-AS1) [155], taurine-upregulated gene 1 (TUG1) [156], SPRY4 intronic transcript 1 (SPRY4-IT1) [157], and promoter of CDKN 1A antisense DNA damage-activated RNA (PANDAR) [158] are found to promote EMT and metastasis in CRC through unknown mechanisms.
