FEZF1 and colorectal carcinoma: FEZF1-AS1 increased the aggressive behavior of colorectal carcinoma cells by increasing the mRNA levels of its corresponding cognate gene, FEZF1, via modulating the transcription of FEZF1 or the stability of its mRNA [6], suggesting the mechanism by which FEZF1-AS1 upregulated FEZF1 protein levels.
