gastric cancer-associated antigen

Fas antigen (Fas) is a type I transmembrane glycoprotein composed of 319 amino acids and belongs to the tumor necrosis factor receptor (TNF-R) and nerve growth factor receptor (NGFR) family members. When it binds to Fas antibody or Fas ligand (FasL), its cytoplasmic region is mediated by a special intracellular protein, which directly activates the apoptotic gene product and induces apoptosis in the cell where Fas antigen is located. The Fas system, which is composed of Fas antigen, Fas antibody or FasL and its intracellular signaling molecules, plays a unique role in the induction of apoptosis, making it a research hotspot in the diagnosis and treatment of malignant tumors.
