Abstract: Src homology region 2-containing protein tyrosine phosphatase 2(SHP2)is the only cytoplasmic protein tyrosine phosphatase that has been confirmed to promote cancer.There are highly expressed in a variety of malignant tumors.SHP2 can promote tumor development and affect tumor prognosis by mediating RAS/ERK,PI3K/Akt,JAK/STAT and other signal pathways downstream of receptor tyrosine kinase(RTK).At the same time,SHP2 is involved in the regulation of immune checkpoint signaling pathways such as PD-1 / PD-L1,CTLA-4,BLTA and TIGIT,and plays an important role in regulating various immune cells in the tumor microenvironment.Targeting SHP2 can treat malignant tumors not only by inhibiting RTK downstream signaling pathways,but also by improving the immune microenvironment.Therefore,SHP2 has the function of dual treatment tumor by immunity and targeting,and it shows extremely high potential and value as a target for anti-tumor therapy.
