KLF15 and colorectal carcinoma: UALCAN database revealed that KLF15 was downregulated in CRC, and more interestingly, KLF15 was predicted by hTFtarget to bind to the promoter region of LINC00689. After linking these data, we then speculate that KLF15 is a potential transcription factor of LINC00689. However, the regulatory relationship between them has not been reported.
