Inhibition of Cholesterol Absorption by Oxidized Cholesterol in Rats

Bioscience, Biotechnology, and Biochemistry, 1994
The effects on cholesterol absorption of oxidized cholesterols were studied in lymph-cannulated rats. When a single emulsified lipid meal containing a tracer amount of [14C]cholesterol with either 50 mg cholesterol or 50 mg oxidized cholesterol mixture was administered intragastrically, the lymphatic absorption of cholesterol for 24 h was 33.1 ± 6.3 ...

Assessment of percent cholesterol absorption in humans with stable isotopes

Journal of Lipid Research, 1993
Dietary cholesterol restriction is a general recommendation for the medical community and emphasizes the importance of intestinal cholesterol absorption and metabolism in humans.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Heritability of plasma noncholesterol sterols and relationship to DNA sequence polymorphism in ABCG5 and ABCG8

Journal of Lipid Research, 2002
The plasma concentrations of cholesterol precursor sterols and plant sterols vary over a 5- to 10-fold range among normolipidemic individuals, and provide indices of the relative rates of cholesterol synthesis and fractional absorption.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Inhibition of lymphatic absorption of cholesterol by cholestane-3β,5α,6β-triol

Journal of Lipid Research, 1969
The effect of cholestane-3β,5α,6β-triol (CT) on the intestinal absorption of cholesterol and oleic acid, as well as the absorption of labeled CT, was studied in lymph duct-cannulated rats.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

The lipid-lowering effect of ezetimibe in pure vegetarians

Journal of Lipid Research, 2006
Results of previous studies have shown that ezetimibe (10 mg/day) reduces LDL cholesterol in patients with mild hypercholesterolemia on a normal-cholesterol diet (dietary intake of 200–500 mg/day) by 16–22%.

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

FEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Evidence for multiple complementary pathways for efficient cholesterol absorption in mice

Journal of Lipid Research, 2005
Apolipoprotein B (apoB)-dependent and apoB-independent pathways for cholesterol transport have been described in cultured cells. Here, we show that the apoB-independent pathway involves apoA-I-containing high density lipoproteins (HDLs).
