CD73 (5'-Nucleotidase Ecto)

HOXD13 orchestrates 3D enhancer-promoter contacts activating VEGFA, SEMA3A, and CD73, which remodel vasculature and elevate immunosuppressive adenosine. Consistently, HOXD13-induced tumor growth is reversed by combined VEGFR and adenosine receptor (AdR) inhibition, revealing a dual pro-angiogenic and immunosuppressive HOXD13 axis with therapeutic relevance.

Mechanistically, RD3 governs a self-reinforcing axis of cellular identity and immunoediting (by regulating T-cell cytokine release, activation, and cytotoxic function), positioning it as a critical checkpoint in NB evolution. These findings establish RD3 as a dual-function molecular switch and nominate RD3-targeted strategies to re-sensitize high-risk NB to immunotherapy.

In addition, ecto-5'-nucleotidases play a role in activating the epithelial-mesenchymal transition. Therefore, ectonucleotidase activity may represent a therapeutic target for the treatment of breast cancer.

PIK3R1 overexpression is linked to poor prognosis in GC and influences the extent of immune cell infiltration within the tumor microenvironment. A novel prognostic model integrating PIK3R1 and CD73 expression with clinical parameters was established to stratify GC patients into distinct risk groups, offering potential value for personalized therapeutic strategies.

Therapeutic cancer vaccines are a new modality in this premise. Finally, an integrated overview of this pathway, along with TIME dynamics, illustrates the barriers and opportunities of combining adenosine signaling inhibitors in clinical trials.

In summary, we demonstrate that protein profiling of EVs in relation to osimertinib refractoriness has the potential to identify possible biomarkers that can indicate osimertinib treatment resistance, for example, CSPG4, HSPG2, TAGLN, TNC, THBS1, ANXA1 and CD73/NT5E. Studies in expanded cohorts should be conducted to further validate these putative osimertinib biomarkers.

By contrast, CARpos T cells obtained from infusion products in long-term responders are enriched in the CD38-CD73-Tim-3-HLA-DR+ phenotype, characterized by a decreased ability to produce adenosine, memory-like transcriptomic characteristics, and leveraging of mitochondrial metabolism and oxidative phosphorylation. Our study reveals that the CD38-CD73-Tim-3-HLA-DR+ phenotype contributes to long-term remission in patients with BCP-ALL who receive tisagenlecleucel.

TCGA analyses, GeoMx digital spatial profiling, and functional analyses showed that CD73 loss drives distinct Wnt-TCF/LEF-dependent gene expression programs linked to cancer cell stemness. These findings identify CD73 as a key regulator of mutant β-catenin, providing mechanistic insight into the variability of recurrence in CTNNB1-mutant EC.

Additionally, the necessity of comprehensively regulating ADO metabolism and the immune microenvironment through multi-level coordinated interventions is also explored, as well as the latest combined regulatory strategies. Moreover, the major challenges in current research on ADO metabolic regulation are also critically analyzed and the future research directions are proposed to address the dual challenges of ADO metabolic diversity and TME complexity, aiming to develop more precise and effective immunotherapeutic strategies.
