AI Article Synopsis

  • Epithelial-mesenchymal transition (EMT) plays a crucial role in cancer progression, invasion, and resistance to therapy, making it an important target for cancer research.
  • The CD73 enzyme has been linked to EMT, as it produces adenosine, which influences cell adhesion and migration, as well as having immunosuppressive effects.
  • An analysis of RNA sequencing data identified a strong correlation between EMT scores and the expression of CD73 and CD39 in various cancers, especially prostate adenocarcinoma, indicating that the interplay between EMT and the adenosine signaling pathway varies by tumor context and could lead to new treatment approaches.

Article Abstract

Epithelial-mesenchymal transition (EMT) is a key mechanism related to tumor progression, invasion, metastasis, resistance to therapy and poor prognosis in several types of cancer. However, targeting EMT or partial-EMT, as well as the molecules involved in this process, has remained a challenge. Recently, the CD73 enzyme, which hydrolyzes AMP to produce adenosine (ADO), has been linked to the EMT process. This relationship is not only due to the production of the immunosuppressant ADO but also to its role as a receptor for extracellular matrix proteins, being involved in cell adhesion and migration. This article reviews the crosstalk between the adenosinergic pathway and the EMT program and the impact of this interrelation on cancer development and progression. An in silico analysis of RNAseq datasets showed that several tumor types have a significant correlation between an EMT score and NT5E (CD73) and ENTPD1 (CD39) expressions, with the strongest correlations being in prostate adenocarcinoma. Furthermore, it is evident that the cooperation between EMT and the adenosinergic pathway in tumor progression is context and tumor-dependent. The increased knowledge about this topic will help broaden the view to explore new treatments and therapies for different types of cancer.

The adenosinergic pathway converting endogenous ATP to adenosine (ADO) is a major immunosuppressive pathway in cancer. Emerging data indicate that plasma small extracellular vesicles (sEV) express CD39 and CD73 and produce ADO. Using a noninvasive, highly sensitive newly developed assay, metabolism of N-etheno-labeled eATP, eADP or eAMP by ecto-nucleotidases on the external surface of sEV was measured using high pressure liquid chromatography with fluorescence detection.

Hypoxia-adenosinergic regulation of B cell responses.

Front Immunol

Department of Pathology, University of Texas Medical Branch, Galveston, TX, United States.

Hypoxic microenvironments induce widespread metabolic changes that have been shown to be critical in regulating innate and adaptive immune responses. Hypoxia-induced changes include the generation of extracellular adenosine followed by subsequent signaling through adenosine receptors on immune cells. This evolutionarily conserved "hypoxia-adenosinergic" pathway of hypoxia → extracellular adenosine → adenosine receptor signaling has been shown to be critical in limiting and redirecting T cell responses including in tumor microenvironments and the gut mucosa.

The Adenosinergic Pathway in Non-Small Cell Lung Cancer.

Immune checkpoint inhibitors (ICIs) targeting PD-(L)1 and CTLA-4 have revolutionized the systemic treatment of non-small cell lung cancer (NSCLC), achieving impressive results. However, long-term clinical benefits are only seen in a minority of patients. Extensive research is being conducted on novel potential immune checkpoints and the mechanisms underlying ICI resistance.

Mesenchymal Stem/Stromal Cells Derived from Dental Tissues Mediate the Immunoregulation of T Cells through the Purinergic Pathway.

Human dental tissue mesenchymal stem cells (DT-MSCs) constitute an attractive alternative to bone marrow-derived mesenchymal stem cells (BM-MSCs) for potential clinical applications because of their accessibility and anti-inflammatory capacity. We previously demonstrated that DT-MSCs from dental pulp (DP-MSCs), periodontal ligaments (PDL-MSCs), and gingival tissue (G-MSCs) show immunosuppressive effects similar to those of BM, but to date, the DT-MSC-mediated immunoregulation of T lymphocytes through the purinergic pathway remains unknown. In the present study, we compared DP-MSCs, PDL-MSCs, and G-MSCs in terms of CD26, CD39, and CD73 expression; their ability to generate adenosine (ADO) from ATP and AMP; and whether the concentrations of ADO that they generate induce an immunomodulatory effect on T lymphocytes.

Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a safe and effective intervention for the treatment of certain forms of epilepsy. In preclinical models, electrical stimulation of the ANT has antiepileptogenic effects but its underlying mechanisms remain unclear. In this review, we searched multiple databases for studies that described the effects and mechanisms of ANT low or high frequency stimulation (LFS or HFS) in models of epilepsy.
