| Abstract |
The study demonstrated that oxidative stress induced by hyperoxia (0.5 MPa for 90 min) resulted in reduction of mRNA levels of transcription factor Nrf2 and Nrf2-induced genes encoding antioxidant enzymes (SOD1, CAT, GPx4) in peripheral blood leukocytes of rats. The changes in gene expression profiles under hyperoxia were accompanied by disbalance of activity of antioxidant enzymes in the leukocytes, namely activation of superoxide dismutase and inhibition of catalase, glutathione peroxidase, and glutathione-S-transferase. Pretreatment of rats with SkQ1 (50 nmol/kg for five days) significantly increased mRNA levels of transcription factor Nrf2 and Nrf2-induced genes encoding antioxidant enzymes SOD2 and GPx4 and normalized the transcriptional activity of the SOD1 and CAT genes in the leukocytes in hyperoxia-induced oxidative stress. At the same time, the activity of catalase and glutathione peroxidase was increased, and the activity of superoxide dismutase and glutathione-S-transferase returned to the control level. It is hypothesized that protective effect of SkQ1 in hyperoxia-induced oxidative stress can be realized via a direct antioxidant property and the stimulation of the Keap1/Nrf2 redox-sensitive signaling system. |

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 15 July 2018.
All research outputs
#20,674,485
of 25,394,764 outputs
Outputs from Biochemistry
#20,704
of 22,298 outputs
Outputs of similar age
#291,518
of 395,031 outputs
Outputs of similar age from Biochemistry
#81
of 141 outputs
Altmetric has tracked 25,394,764 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 22,298 research outputs from this source. They receive a mean Attention Score of 4.4. This one is in the 3rd percentile – i.e., 3% 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 395,031 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 141 others from the same source and published within six weeks on either side of this one. This one is in the 9th percentile – i.e., 9% of its contemporaries scored the same or lower than it.
