ARTICLE ABSTRACT
Posttranslational modification of proteins increases their diversity and maintains the stability of the intracellular environment. Protein arginine methyltransferases (PRMT) are an important family of epigenetic modification enzymes, which play a critical role in posttranslational modification. In recent years, with the in-depth study of the role of epigenetics, the structure and function of PRMTs have been gradually understood. PRMT enzymatic activity is related to a variety of cellular processes in digestive system malignancies, such as inflammation and immune response, activation of cell cycle and proliferation, inhibition of apoptosis, DNA damage repair, and epithelial–mesenchymal transition. A variety of chemical tools are developed to inhibit PRMT activity, which have been verified by tumor models and clinical trials. This review summarizes the structure and functions of PRMTs as a prelude to our further studies on their role in tumors. The involvement of different PRMTs in the pathogenesis of gastrointestinal tumors is then reviewed. In addition, the application of PRMT inhibitors as therapeutic agents for digestive system cancers is highlighted. In conclusion, PRMTs play an important role in the pathogenesis of gastrointestinal tumors, and their prognostic and therapeutic potential warrants further investigation.
