Abstract

Angiogenesis is a process by which vessels are formed through preexisting ones, and this plays a key role in the progression of solid tumors. However, tumor vessels are influenced by excessive pro-angiogenic factors, resulting in deformed structures that facilitate the intravasation of tumor cells into the circulation and subsequent metastasis. Moreover, abnormal tumor vessels have low blood perfusion and thereby decreased oxygen infusion into tumors. This results in a hostile microenvironment that promotes epithelial-mesenchymal transition (EMT), a process in which epithelial cells lose their polarity and gain increased motility, which is associated with metastasis and invasion. Here, we demonstrate that gold nanoparticles (AuNPs) facilitate tumor vasculature normalization, increase blood perfusion and alleviate hypoxia in melanoma tumors. Additionally, AuNPs were observed to reverse EMT in tumors, accompanied by the alleviation of lung metastasis. These AuNPs inhibited the migration of B16F10 cells and reversed EMT in B16F10 cells, indicating that AuNPs could directly regulate EMT independent of improvements in hypoxia. Taken together, our data demonstrated that AuNPs could induce tumor vasculature normalization and reverse EMT, resulting in decreased melanoma tumor metastasis.

Attention Score in Context

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 13 May 2017.
All research outputs
#22,764,772
of 25,382,440 outputs
Outputs from International Journal of Nanomedicine
#3,598
of 4,122 outputs
Outputs of similar age
#284,174
of 324,557 outputs
Outputs of similar age from International Journal of Nanomedicine
#60
of 80 outputs
Altmetric has tracked 25,382,440 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 4,122 research outputs from this source. They receive a mean Attention Score of 4.7. 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 324,557 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 80 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.
