| Abstract |
Endothelial cell function is critical for angiogenic balance in both physiological and pathological conditions, such as wound healing and cancer, respectively. We report here that soluble heat shock protein beta-1 (HSPB1) is released primarily from endothelial cells (ECs), and plays a key role in regulating angiogenic balance via direct interaction with vascular endothelial growth factor (VEGF). VEGF-mediated phosphorylation of intracellular HSPB1 inhibited the secretion of HSPB1 and their binding activity in ECs. Interestingly, co-culture of tumor ECs with tumor cells decreased HSPB1 secretion from tumor ECs, suggesting that inhibition of HSPB1 secretion allows VEGF to promote angiogenesis. Additionally, neutralization of HSPB1 in a primary mouse sarcoma model promoted tumor growth, indicating the anti-angiogenic role of soluble HSPB1. Overexpression of HSPB1 by HSPB1 adenovirus was sufficient to suppress lung metastases of CT26 colon carcinoma in vivo, while neutralization of HSPB1 promoted in vivo wound healing. While VEGF-induced regulation of angiogenesis has been studied extensively, these findings illustrate the key contribution of HSPB1-VEGF interactions in the balance between physiological and pathological angiogenesis. |

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 February 2012.
All research outputs
#20,155,513
of 22,663,150 outputs
Outputs from Angiogenesis
#439
of 536 outputs
Outputs of similar age
#141,807
of 156,295 outputs
Outputs of similar age from Angiogenesis
#8
of 13 outputs
Altmetric has tracked 22,663,150 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 536 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.1. 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 156,295 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 13 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.
