Background
ART1 (ADP-ribosyltransferase 1) is a glycosylphosphatidylinositol (GPI)-anchored mono-ADP-ribosyltransferase containing an extracellular catalytic domain that modifies target proteins through ADP-ribosylation, thereby regulating diverse cellular functions. Research has demonstrated that ART1 is highly expressed in various cancers (e.g., colorectal cancer, non-small cell lung cancer, and glioblastoma) and associated with poor prognosis. In the tumor microenvironment, ART1 binds to the P2X7 receptor (P2X7R) on CD8⁺ T cells, inducing T cell death and promoting immune evasion and resistance to immune checkpoint inhibitors (ICIs). Additionally, in colorectal cancer, ART1 activates the AKT/mTOR/STAT3 signaling pathway to drive tumor proliferation and enhances tumor growth under high norepinephrine conditions, which is linked to diabetes-associated colorectal cancer progression. Recent studies have identified that ART1-specific antibodies can reverse its immunosuppressive effects and boost anti-tumor immune responses, positioning ART1 as a promising novel target for cancer immunotherapy.
