| Abstract |
Arsenic trioxide (As2O3; ATO), a traditional Chinese medicine, is used to treat patients with acute promye-locytic leukemia, while its application for treatment of systemic lupus erythematosus (SLE) is still under evaluation. The high expression of INF-gamma (INF-γ) is a primary pathogenic factor in SLE. It is found that ATO can reduce INF-γ expression levels in lupus-prone mice, whereas it is not clear whether ATO has the same effect on SLE patients. Therefore, this study was to investigate the underlying mechanism of the effects of ATO on the expression of INF-γ in splenocytes of MRL/lpr mice and PBMCs of human lupus. The mRNA and protein expression levels of INF-γ were assessed by real-time RT-PCR and ELISA, respectively. The histone acetylation status of the INF-γ promoter and the binding of RNA polymerase II (RNA Pol II) to the INF-γ promoter were detected using a chromatin immunoprecipitation (ChIP) technique. The mRNA and protein expression levels of INF-γ decreased in both splenocytes of MRL/lpr mice and PBMCs of SLE patients with ATO treatment, which were accompanied by reduced histone H4 and H3 acetylation in INF-γ promoter and decreased combination of RNA Pol II to the INF-γ promoter. Therefore, ATO may reduce the expression level of the INF-γ by altering the levels of INF-γ promoter acetylation and the combination of RNA Pol II to the INF-γ promoter in splenocytes of MRL/lpr mice and PBMCs of SLE patients. |

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 November 2017.
All research outputs
#18,576,855
of 23,008,860 outputs
Outputs from Biological Trace Element Research
#1,337
of 2,051 outputs
Outputs of similar age
#325,380
of 437,492 outputs
Outputs of similar age from Biological Trace Element Research
#8
of 22 outputs
Altmetric has tracked 23,008,860 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,051 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 22nd percentile – i.e., 22% 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 437,492 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 14th percentile – i.e., 14% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 22 others from the same source and published within six weeks on either side of this one. This one is in the 40th percentile – i.e., 40% of its contemporaries scored the same or lower than it.
