Cholesterol oxides inhibit cholesterol esterification by lecithin: cholesterol acyl transferase [PDF]

open access: yesBrazilian Journal of Pharmaceutical Sciences, 2009
Cholesterol oxides are atherogenic and can affect the activity of diverse important enzymes for the lipidic metabolism. The effect of 7β-hydroxycholesterol, 7-ketocholesterol, 25-hydroxycholesterol, cholestan-3β,5α,6β-triol,5,6β ...

Small Dense LDL: Scientific Background, Clinical Relevance, and Recent Evidence Still a Risk Even with ‘Normal’ LDL-C Levels

open access: yesBiomedicines, 2022
Residual cardiovascular disease event risk, following statin use and low-density lipoprotein cholesterol (LDL-C) reduction, remains an important and common medical conundrum.

Cholesterol and Cholesterol Esters in Mycoplasma [PDF]

open access: yesJournal of General Microbiology, 1965
Free and esterified cholesterol were determined in the lipid extract of nine parasitic and saprophytic Mycoplasma strains. The saprophytic strains were usally free from esterified cholesterol. Esterified cholesterol was found in the parasitic strains at a ratio of 1:8 to 1:3 to free cholesterol; in the growth medium the ratio was about 4:1 [4-14C ...

Tracking cell cholesterol with cholesterol oxidase.

open access: yesJournal of Lipid Research, 1992
Sterols are ubiquitous and essential constituents of all eukaryotic cells, found either esterified and stored in droplet form (l), or unesterified and integrated into bilayers (2) . Sterols not only play a major structural role in membranes, but serve as precursors for steroid hormones and bile acids (3). The distribution of cholesterol within the cell

Regulation of cholesterol homeostasis in health and diseases: from mechanisms to targeted therapeutics

open access: yesSignal Transduction and Targeted Therapy, 2022
Disturbed cholesterol homeostasis plays critical roles in the development of multiple diseases, such as cardiovascular diseases (CVD), neurodegenerative diseases and cancers, particularly the CVD in which the accumulation of lipids (mainly the ...

Targeting the liver X receptor with dendrogenin A differentiates tumour cells to secrete immunogenic exosome‐enriched vesicles

open access: yesJournal of Extracellular Vesicles, 2022
Tumour cells are characterized by having lost their differentiation state. They constitutively secrete small extracellular vesicles (sEV) called exosomes when they come from late endosomes.

Liposomes: Structure, Biomedical Applications, and Stability Parameters With Emphasis on Cholesterol

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Liposomes are essentially a subtype of nanoparticles comprising a hydrophobic tail and a hydrophilic head constituting a phospholipid membrane. The spherical or multilayered spherical structures of liposomes are highly rich in lipid contents with ...

Estimation of the concentration of low-density lipoprotein cholesterol in plasma, without use of the preparative ultracentrifuge.

open access: yesClinical Chemistry, 1972
A method for estimating the cholesterol content of the serum low-density lipoprotein fraction (Sf0-20) is presented. The method involves measurements of fasting plasma total cholesterol, triglyceride, and high-density lipoprotein cholesterol ...

Breaking the Cycle, Cholesterol Cycling, and Synapse Damage in Response to Amyloid-ß [PDF]

open access: yes, 2017
Soluble amyloid-β (Aβ) oligomers, a key driver of pathogenesis in Alzheimer disease, bind to cellular prion proteins (PrPC) expressed on synaptosomes resulting in increased cholesterol concentrations, movement of cytoplasmic phospholipase A2 (cPLA2) to ...

Cholesterol Efflux and Reverse Cholesterol Transport [PDF]

open access: yes, 2014
Both alterations of lipid/lipoprotein metabolism and inflammatory events contribute to the formation of the atherosclerotic plaque, characterized by the accumulation of abnormal amounts of cholesterol and macrophages in the artery wall. Reverse cholesterol transport (RCT) may counteract the pathogenic events leading to the formation and development of ...
