Then, online database GEPIA37, which is a newly developed interactive web server for analyzing the RNA sequencing expression data of tumors and normal samples from the TCGA projects, was used to assess the expression of POFTU1 in human CRC tissue and non-tumor tissue, the result found that the expression level of POFUT1 is significantly higher in colorectal cancer tissues than normal tissues (Fig. 1b). Here, POFUT1 is linked to colorectal cancer.
