Effects of pravastatin and cholestyramine on products of the mevalonate pathway in familial hypercholesterolemia.

open access: yesJournal of Lipid Research, 1991
Patients with heterozygous familial hypercholesterolemia (n = 12) were treated either with pravastatin, a specific inhibitor of HMG-CoA reductase, or cholestyramine, followed by a period of combined treatment with both drugs.

Multi-scale Molecular Simulations on Respiratory Complex I [PDF]

open access: yesChemical Biology No. 5 (2018), 2019
Complex I (NADH:ubiquinone oxidoreductase) is a redox-driven proton pump that powers synthesis of adenosine triphosphate (ATP) and active transport in most organisms. This gigantic enzyme reduces quinone (Q) to quinol (QH2) in its hydrophilic domain, and transduces the released free energy into pumping of protons across its membrane domain, up to ca ...

Mitochondrial dysfunction: Related diseases, influencing factors, and detection

open access: yesInterdisciplinary Medicine, EarlyView.
Mitochondrial dysfunction is implicated in the pathogenesis of numerous diseases, including neurological disorders, cancers, and cardiovascular conditions, through mechanisms such as mitochondrial DNA mutations, dysregulation of mitochondrial network dynamics, and impaired mitophagy.

Quantum coherent contributions in biological electron transfer [PDF]

open access: yesarXiv, 2011
Many biological electron transfer (ET) reactions are mediated by metal centres in proteins. NADH:ubiquinone oxidoreductase (complex I) contains an intramolecular chain of seven iron-sulphur (FeS) clusters, one of the longest chains of metal centres in biology and a test case for physical models of intramolecular ET.

Specific interaction between protein and ubiquinone in succinate-ubiquinone reductase.

open access: yesJournal of Biological Chemistry, 1982
The lack of ubiquinone in the isolated succinate-ubiquinone reductase (Complex II) and in some preparations of ubiquinone-binding protein (QPs) has caused some concern about the nature of interaction between ubiquinone and QPs. When a low concentration of radioactively labeled ubiquinone derivative in dilute detergent solution was incubated with ...

Proteomic Profiling Informs Mechanisms of Esophageal Adenocarcinoma Inhibition by Cranberry Proanthocyanidins

open access: yesMolecular Nutrition &Food Research, EarlyView.
In this study we utilized proteomic profiling to investigate mechanisms linked to the cancer‐inhibitory effect of cranberry proanthocyanidins (CPACs) on reflux‐induced esophageal adenocarcinoma in a rat model. The results indicate that CPAC inhibits cancer through targeting multiple hallmarks of cancer known to be dysregulated in progression to ...

Bioavailability of Coenzyme Q10: An Overview of the Absorption Process and Subsequent Metabolism

open access: yesAntioxidants, 2020
A lack of understanding of the processes determining the absorption and subsequent metabolism of coenzyme Q10 (CoQ10) has resulted in some manufacturers’ making incorrect claims regarding the bioavailability of their CoQ10 supplements, with potential ...
