| Abstract |
We have previously showed the presence of the simian virus 40 (SV40) and the mouse mammary tumor virus (MMTV)-like in a significant proportions of Tunisian breast carcinomas. However, to date there are no published studies concerning evaluation of the possible implication of the human polyomaviruses JC (JCV) and BK (BKV) in breast carcinomas. The presence of JCV and BKV DNA was investigated by PCR in a 123 primary breast carcinomas and matched adjacent non-tumor breast tissues. The results were correlated to clinicopathological and virological parameters. JCV T-antigen DNA was detected in 23% of breast carcinoma cases; however, all cases were negative for BKV. JCV T antigen PCR products were further confirmed as authentic JCV genome by direct sequencing. JCV was found in invasive ductal carcinomas (28/112 cases) but not in invasive lobular carcinomas (0/5) or medullary carcinomas (0/6). JCV DNA presence correlates inversely with the expression of estrogen (P = 0.022) and progesterone (P = 0.008) receptors. JCV DNA presence correlates also with "triple negative" phenotype (P = 0.021). With regard to virological data, a trend toward an inverse correlation was noted between the presence of JCV and SV40 (P = 0.06). Moreover, significant correlation was found between multiple viral infection (JCV, and/or SV40, and/or MMTV-like in the same tumor) and "triple negative" phenotype (P = 0.001) and also with p53 accumulation (P = 0.028). To the best of our knowledge, this is the first study demonstrating the presence of JCV in a subset of breast carcinomas. Also our results suggest that "triple negative" breast carcinomas are viral-related tumors. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. 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 27 February 2019.
All research outputs
#6,909,831
of 22,659,164 outputs
Outputs from Breast Cancer Research and Treatment
#1,495
of 4,612 outputs
Outputs of similar age
#62,948
of 239,459 outputs
Outputs of similar age from Breast Cancer Research and Treatment
#19
of 52 outputs
Altmetric has tracked 22,659,164 research outputs across all sources so far. This one has received more attention than most of these and is in the 68th percentile.
So far Altmetric has tracked 4,612 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.2. This one has gotten more attention than average, scoring higher than 66% of its peers.
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 239,459 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 72% of its contemporaries.
We're also able to compare this research output to 52 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
