| Abstract |
The ectonucleotidase CD39 is pivotal in the conversion of immunostimulatory adenosine triphosphate (ATP) into immunosuppressive adenosine which potently inhibits host immune responses against cancer. This study investigated the expression level and prognostic significance of CD39 in human rectal adenocarcinoma. Our data demonstrated that CD39 staining strongly marked malignant epithelial cells where the protein and messenger RNA (mRNA) expression levels of CD39 were significantly increased compared with paracancerous controls. In addition to primary tumors, CD39 was also abundantly expressed in liver metastases and tumor-draining lymph nodes from metastatic rectal adenocarcinoma. Although patients with higher CD39 density in tumor cells were more likely to have favorable characteristics (early TNM and N stages) and overall survival, the singular parameter cannot be used as an independent factor for predicting patients' prognosis. Intriguingly, combined analysis of CD39 and CD73 expression was more efficient to foretell patient's outcome where patients with increased CD73 but decreased CD39 levels displayed a worst prognosis. Taken together, the current study revealed that malignant epithelial cells of human rectal adenocarcinoma strongly express CD39 that may play a potential role in the tumor invasion and metastasis. Although high expression of CD39 in tumor cells is correlated with favorable clinical outcome, the combination of CD39 and CD73 expression may have a better prognostic value. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 April 2016.
All research outputs
#20,322,106
of 22,865,319 outputs
Outputs from Tumor Biology
#1,835
of 2,623 outputs
Outputs of similar age
#219,415
of 263,217 outputs
Outputs of similar age from Tumor Biology
#106
of 164 outputs
Altmetric has tracked 22,865,319 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,623 research outputs from this source. They receive a mean Attention Score of 2.3. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 263,217 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 164 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
