Evidence for a common biliary cholesterol and VLDL cholesterol precursor pool in rat liver.

Journal of Lipid Research, 1992
Hepatic free cholesterol levels are influenced by cholesterol synthesis and ester formation, which, in turn, might regulate cholesterol secretion into bile and plasma.

The Role of Obesity in the Association Between Alcohol Consumption and HDL‐c Levels: Baependi Heart Study

Lipids, EarlyView.
ABSTRACT Cardiovascular diseases (CVD) are a leading cause of global mortality, with dyslipidemia playing a central role in their pathogenesis. The influence of alcohol consumption on lipid profiles, particularly high‐density lipoprotein cholesterol (HDL‐c), in relation to obesity status remains insufficiently explored.

Role of lecithin:cholesterol acyltransferase and apolipoprotein A-I in cholesterol esterification in lipoprotein-X in vitro

Journal of Lipid Research, 1995
Lipoprotein-X (Lp-X) is an abnormal particle present in the plasma of patients with familial lecithin:cholesterol acyltransferase (LCAT) deficiency syndromes or cholestatic liver disease.

Esterification of 4β-hydroxycholesterol and other oxysterols in human plasma occurs independently of LCAT

Journal of Lipid Research, 2020
The acyltransferase LCAT mediates FA esterification of plasma cholesterol. In vitro studies have shown that LCAT also FA-esterifies several oxysterols, but in vivo evidence is lacking. Here, we measured both free and FA-esterified forms of sterols in 206

Introducing the concept of biocatalysis in the classroom: The conversion of cholesterol to provitamin D 3 [PDF]

, 2016
Biocatalysis is a fundamental concept in biotechnology. The topic integrates knowledge of several disciplines; therefore, it was included in the course “design and optimization of biological systems” which is offered in the biochemistry curricula.

Unilateral mastication‐induced memory deficits linked to disrupted hippocampal cholesterol metabolism in rats

VIEW, EarlyView.
Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

Hepatic esterification rate of cholesterol and biliary lipids in human obesity.

Journal of Lipid Research, 1994
Obesity is often associated with an increased hepatic secretion rate of cholesterol and saturated gallbladder bile. In order to evaluate the role of hepatic esterification of cholesterol in this phenomenon, we assayed the activity of acyl CoA:cholesterol

Advances in cholesterol and lipoproteins detection for healthcare: A review

VIEW, EarlyView.
Cholesterol is one of the main biomarkers related to the development of cardiovascular diseases. Its detection still relies on traditional methods of analysis, such as gas and liquid chromatographies. Detection of free cholesterol in saliva with redox or enzymatic sensors or detection of lipoproteins in blood with aptamer sensors are currently the most

Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability

Andrology, EarlyView.
ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Esterification of plasma membrane cholesterol and triacylglycerol-rich lipoprotein secretion in CaCo-2 cells: possible role of p-glycoprotein

Journal of Lipid Research, 1995
Acylcoenzyme A:cholesterol acyltransferase (ACAT) and/or cholesteryl esters have been implicated as important factors in the normal assembly of apolipoprotein (apoB)-containing lipoproteins.
