| Abstract |
Chronic exposure to arsenic is associated with various diseases in humans. Skin hyperpigmentation is the most sensitive objective symptom for patients with arsenicosis. However, there is very limited information about the mechanism of arsenic-mediated skin hyperpigmentation in vivo. In this study, hairless homozygous mice (Hr/Hr-mice) that drank water containing 3 and 30 µM arsenic for 2 months developed skin hyperpigmentation with increased levels of arsenic and number of melanocytes in the skin. Since it is possible for humans to be exposed to 3 µM of arsenic in well drinking water, our results suggest that the Hr/Hr-mice could be a novel model sensitively reflecting arsenic-mediated skin hyperpigmentation. We then analyzed the mechanism of arsenic-mediated skin hyperpigmentation. The epidermis of Hr/Hr-mice and human HaCaT skin keratinocytes exposed to arsenic for 2 and 4 months, respectively, showed 5.4-21.5-fold increased levels of endothelin-1 (ET-1) expression via NF-kappa B activation. Coexposure of primary normal human epithelial melanocytes to arsenic and ET-1 activated their proliferation and melanin synthesis with increased levels of MITF-M and ET-1 receptor expression. Our results suggest that interaction between keratinocytes and melanocytes in the skin through ET-1 and its receptor contributes to arsenic-mediated skin pigmentation, a hallmark of arsenicosis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 9. 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 11 August 2022.
All research outputs
#3,449,906
of 23,743,910 outputs
Outputs from Archives of Toxicology
#266
of 2,670 outputs
Outputs of similar age
#63,114
of 312,209 outputs
Outputs of similar age from Archives of Toxicology
#12
of 29 outputs
Altmetric has tracked 23,743,910 research outputs across all sources so far. Compared to these this one has done well and is in the 84th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,670 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.3. This one has done well, scoring higher than 86% 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 312,209 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 79% of its contemporaries.
We're also able to compare this research output to 29 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 62% of its contemporaries.
