The contribution of fucosyltransferases to cancer biology.

Fucosyltransferases are enzymes that transfer L-fucose residues from a donor substrate to target molecules. These enzymes are encoded by genes known as FUTs (FUT1 to FUT-11), along with POFUT1 and 2. Changes in FUT expression have a significant role in cancer development and malignancy. This review delves into the biochemistry and biological functions of FUTs and their contributions to cancer. Broadly, FUTs play roles in cancer tumorigenesis, survival, and metastasis. Interactions between fucosylated glycans and various molecules associated with cancer, such as E-selectins and the epidermal growth factor receptor (EGFR), offer alternative pathways for cancer development. The review also highlights FUTs as potential biomarkers for cancer prognosis and diagnosis, along with their application as targets for therapy.
