Selenium nanoparticles show limited effectivenessSelenium nanoparticles inhibit the formation of atherosclerosis in apolipoprotein E deficient mice by alleviating hyperlipidemia and oxidative stress.
We investigated whether selenium nanoparticles (SeNPs) could combat atherosclerosis related to high cholesterol. In our study involving apolipoprotein E deficient mice on a high-fat diet, both BSA- and chitosan-coated SeNPs showed promise in reducing atherosclerotic lesions over 12 weeks.
The nanoparticles seemed to work by lowering cholesterol levels and boosting antioxidant activity. While results were notably stronger for BSA-SeNPs, there was no significant evidence to suggest that SeNPs drastically alter cholesterol levels overall, indicating that further research is necessary.

Selenium nanoparticles reduce cholesterolSelenium nanoparticles alleviate hyperlipidemia and vascular injury in ApoE-deficient mice by regulating cholesterol metabolism and reducing oxidative stress.
We explored the effects of selenium nanoparticles on high cholesterol by studying ApoE-deficient mice on a high-fat diet. Over eight weeks, we noted that selenium nanoparticles significantly reduced total cholesterol and triglycerides while boosting beneficial HDL levels.
Additionally, these nanoparticles improved vascular health and regulated important genes for cholesterol metabolism while enhancing antioxidant enzyme activities. However, it's important to note that while the results were promising in mice, the findings do not directly translate to humans yet.

Selenium may help cholesterol levelsHypercholesterolemia and LDL receptor mRNA expression: modulation by selenium supplementation.
We investigated the effects of selenium supplementation on LDL receptor activity and mRNA expression in male rats with high cholesterol. The study involved feeding the rats diets with varying selenium levels along with a high-cholesterol diet over three months.
Our results showed that while high cholesterol reduced both LDL receptor activity and mRNA expression, selenium at 1 ppm effectively improved these measures. This suggests that selenium may play a positive role in managing cholesterol levels and supporting lipid metabolism.

Selenium supports cholesterol managementModulation of hypercholesterolemia-induced alterations in apolipoprotein B and HMG-CoA reductase expression by selenium supplementation.
We investigated how selenium supplementation affects cholesterol levels and the associated molecular changes. Using Sprague-Dawley male rats, we fed them diets supplemented with selenium alongside high cholesterol for three months.
The results showed that while apolipoprotein B levels rose with the cholesterol diet, supplementing with 1 ppm of selenium significantly reduced these levels. Additionally, the expression of HMG-CoA reductase also decreased with selenium supplementation.
Overall, our findings suggest that selenium could offer a supportive role in managing lipid metabolism and high cholesterol.

Selenium reduces cholesterol in rats[Effect of selenium on serum, hepatic and lipoprotein lipids concentration in rats fed on a high-cholesterol diet].
We explored how selenium affects lipid levels in rats consuming a high-cholesterol diet over ten weeks. By comparing selenium-treated groups with control rats, we found that selenium effectively reduced triglycerides, total cholesterol, and low-density lipoprotein cholesterol.
Additionally, it inhibited liver fat accumulation. These findings suggest that selenium could play a beneficial, recuperative role against high cholesterol. However, it's important to note that this research is based on animal studies, so human applicability requires further investigation.
