| Abstract |
Clinical studies indicate that vitamin D3 improves circulation and may have beneficial effects in hypertension. This study uses nanomedical systems to investigate the role of 1,25-dihydroxy vitamin D3 in the preservation/restoration of endothelial function in an angiotensin II (Ang II) cellular model of hypertension. 1,25-dihydroxy vitamin D3-stimulated nitric oxide (NO) and peroxynitrite (ONOO-) concentrations were measured in situ with nanosensors (200-300 mm diameter with a detection limit of 1 nM) in human umbilical vein endothelial cells of African American (AA) and Caucasian American (CA) donors exposed to Ang II. The balance/imbalance between NO and ONOO- concentrations ([NO]/[ONOO-]) was simultaneously monitored and used as an indicator of endothelial nitric oxide synthase (eNOS) uncoupling and endothelial dysfunction. [NO]/[ONOO-] imbalance in Ang II-stimulated dysfunctional endothelium was 0.20±0.16 for CAs and 0.11±0.09 for AAs. Uncoupled eNOS and overexpression of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase contributed to high production of ONOO-. Vitamin D3 treatment reversed [NO]/[ONOO-] to 3.0±0.1 in CAs and 2.1±0.1 in AAs - exceeding that observed in normal endothelium. Vitamin D3 restored uncoupled eNOS and endothelial function by increasing cytoprotective NO and decreasing the cytotoxic ONOO-. The beneficial effect of vitamin D3 is associated with a favorable rate of NO and ONOO- release, restoration of the [NO]/[ONOO-] and the overall decrease in the overexpression of eNOS, inducible nitric oxide synthase and NADPH oxidase. This effect of vitamin D3 may prove to be beneficial in the treatment of hypertension and other cardiovascular diseases, including heart failure, myocardial infarction, vasculopathy, stroke and diabetes. |

Attention Score in Context
This research output has an Altmetric Attention Score of 361. 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 04 December 2023.
All research outputs
#88,565
of 25,403,829 outputs
Outputs from International Journal of Nanomedicine
#8
of 4,123 outputs
Outputs of similar age
#2,115
of 449,628 outputs
Outputs of similar age from International Journal of Nanomedicine
#2
of 65 outputs
Altmetric has tracked 25,403,829 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,123 research outputs from this source. They receive a mean Attention Score of 4.7. This one has done particularly well, scoring higher than 99% 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 449,628 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 65 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 98% of its contemporaries.
