Specifically, the increase of the OGT has been observed in different types of tumor, such as breast [82,83,84,85,86], colon [87,88], liver [89], endometrial [90], cervical [91], lung [87], prostate [41,92] and pancreatic [93] cancer, and it has often been associated with a parallel decrease of either the OGA levels or the OGA/OGT ratio [86,89,92]. This evidence concerns the gene OGT and cancer.
