“…Finally, our findings would be strengthened by genetic knockdown of CD73 expression. Although the authors have explored use of a CD73‐deficient MSC line, current evidence suggests that CD73 may be critical for cell proliferation 69, 70. Knockdown of this enzyme may limit MSC growth kinetics in vitro, which presents unique challenges for expansion before implantation, and thus requires further study.…”

BackgroundDuring myocardial ischemia/reperfusion (MI/R) injury, there is extensive release of immunogenic metabolites that activate cells of the innate immune system. These include ATP and AMP, which upregulate chemotaxis, migration, and effector function of early infiltrating inflammatory cells. These cells subsequently drive further tissue devitalization. Mesenchymal stromal cells (MSCs) are a potential treatment modality for MI/R because of their powerful anti‐inflammatory capabilities; however, the manner in which they regulate the acute inflammatory milieu requires further elucidation. CD73, an ecto‐5′‐nucleotidase, may be critical in regulating inflammation by converting pro‐inflammatory AMP to anti‐inflammatory adenosine. We hypothesized that MSC‐mediated conversion of AMP into adenosine reduces inflammation in early MI/R, favoring a micro‐environment that attenuates excessive innate immune cell activation and facilitates earlier cardiac recovery.Methods and ResultsAdult rats were subjected to 30 minutes of MI/R injury. MSCs were encapsulated within a hydrogel vehicle and implanted onto the myocardium. A subset of MSCs were pretreated with the CD73 inhibitor, α,β‐methylene adenosine diphosphate, before implantation. Using liquid chromatography/mass spectrometry, we found that MSCs increase myocardial adenosine availability following injury via CD73 activity. MSCs also reduce innate immune cell infiltration as measured by flow cytometry, and hydrogen peroxide formation as measured by Amplex Red assay. These effects were dependent on MSC‐mediated CD73 activity. Finally, through echocardiography we found that CD73 activity on MSCs was critical to optimal protection of cardiac function following MI/R injury.Conclusions MSC‐mediated conversion of AMP to adenosine by CD73 exerts a powerful anti‐inflammatory effect critical for cardiac recovery following MI/R injury.

“…The final dephosphorylation of nucleotides, conversion of nucleoside monophosphates (e.g., AMP) to their respective nucleosides (e.g., adenosine), is catalyzed by ecto-5′-nucleotidase/CD73 (ecto-5′-NT/CD73). This enzyme is highly expressed in a variety of solid tumors [19][20][21][22] and has both its enzymatic activity and its adhesion protein function associated with cancer progression [23,24]. Besides, ecto-5′-NT/CD73 was found to be involved in cancer cell growth, maturation, differentiation, adhesion, migration, invasiveness, metastasis, immune escape, and drug resistance [19,[21][22][23][24][25][26][27].…”

According to the World Health Organization, bladder cancer is the seventh most common cancer among men in the world. The current treatments for this malignancy are not efficient to prevent the recurrence and progression of tumors. Then, researches continue looking for better therapeutic targets which can end up in new and more efficient treatments. One of the recent findings was the identification that the purinergic system was involved in bladder tumorigenesis. The ectonucleotidases, mainly ecto-5′-nucleotidase/CD73 have been revealed as new players in cancer progression and malignity. In this work, we investigated the NTPDase3 and ecto-5′-nucleotidase/CD73 expression in cancer progression in vivo. Bladder tumor was induced in mice by the addition of 0.05 % of N-butyl-N-(hydroxybutyl)-nitrosamine (BBN) in the drinking water for 4, 8, 12, 18, and 24 weeks. After this period, mice bladders were removed for histopathology analysis and immunofluorescence assays. The bladder of animals which has received BBN had alterations, mainly inflammation, in initial times of tumor induction. After 18 weeks, mice's bladder has developed histological alterations similar to human transitional cell carcinoma. The cancerous urothelium, from mice that received BBN for 18 and 24 weeks, presented a weak immunostaining to NTPDase3, in contrast to an increased expression of ecto-5′-nucleotidase/CD73. The altered expression of NTPDase3 and ecto-5′-nucleotidase/ CD73 presented herein adds further evidence to support the idea that alterations in ectonucleotidases are involved in bladder tumorigenesis and reinforce the ecto-5′-nucleotidase/ CD73 as a future biomarker and/or a target for pharmacological therapy of bladder cancer.

“…Cells positive for CD73 through the production of immunosuppressive adenosine are more able to evade anti-tumor immune responses (48). These findings indicate that CD73 is associated with tumor proliferation, metastasis and invasion (7,8,44,49). By contrast, the suppression of CD73 induces apoptosis and cell-cycle arrest in human breast cancer cells (50), and the inhibition of adenosine production by CD73 could be a therapeutic target for the prevention of tumor angiogenesis and metastasis (14).…”

“…At present, it is challenging to estimate the relative contribution of cancer cells compared with other cells or exosomes that contribute to adenosine production in the tumor microenvironment in vivo. However, the majority of findings strongly indicate that CD73 functions at multiple levels in limiting antitumor effects (44). Although the vascular expression of CD73 in RCC samples was not significantly different from that of normal renal cells, CD73 may play other roles in RCC progression.…”

Abstract. Renal cell carcinoma (RCC) is a common tissue tumor that occurs across all age groups and has become one of the types of cancer with the fastest increasing incidence. Due to the resistance of RCC chemo-and radiotherapy, surgery is the only currently effective treatment. Therefore, specific markers for the diagnosis and prognosis of RCC are expected to result in novel methods of treatment. Ecto-5'-nucleotidase, also termed cluster of differentiation (CD)73, is a protein that is activated in several types of aggressive cancer and may promote cancer progression. CD73 was examined in the present study to determine the association between the protein and RCC. The expression levels of CD73 in 159 RCC tissue sections and 30 paratumorous normal renal tissue samples obtained from 235 patients that underwent nephrectomy were examined by immunohistochemical staining. By contrast, the expression level of P-glycoprotein (P-gp), a potential prognostic factor in RCC, was also examined in 85 RCC and 13 normal tissue samples. Intense CD73 expression was identified in 75 out of 159 RCC cell membranes compared with normal renal tissues. In contrast, there was high P-gp expression in the blood vessels of 42 out of 85 RCC tissues and there was no significant difference between the P-gp expression identified in RCC cells (34 out of 85) and the cell membrane of normal renal cells (2 out of 13). The expression level of CD73 in RCC cells was significantly associated with tumor type, tumor node metastasis (TNM) stage, and tumor grade. However, the expression of P-gp in RCC cells was only associated with the TNM stage and tumor grade. Using a multivariable Cox regression analysis, it was found that the median survival rate of RCC patients with intense CD73 expression in RCC cells was 62.06±5.35 months, which was drastically shorter compared with rare CD73 expression (103.72±3.67 months). In conclusion, the expression level of CD73 is significantly associated with RCC tumor progression and may serve as a favorable marker for the diagnosis and prognosis of RCC, in addition to being a therapeutic target for the treatment of RCC.
