Quantifying Cellular Cholesterol Efflux.

Measuring cholesterol efflux involves the tracking of cholesterol movement out of cells. Cholesterol efflux is an essential mechanism to maintain cellular cholesterol homeostasis, and this process is ...

Competition for Food Drives Stem Cell Fate in Facultative Niches.

Mechanisms regulating maintenance of the stem cell pool in facultative niches of the mammalian testis are poorly understood. In this issue of Cell Stem Cell, Kitadate et al. (2019) propose a minimal ...

Brain expansion promoted by polycomb-mediated anterior enhancement of a neural stem cell proliferation program.

During central nervous system (CNS) development, genetic programs establish neural stem cells and drive both stem and daughter cell proliferation. However, the prominent anterior expansion of the CNS ...

Cholesterol-dependent Modulation of Stem Cell Biomechanics: Application to Adipogenesis.

Cell mechanics has been shown to regulate stem cell differentiation. We have previously reported that altered cell stiffness of mesenchymal stem cells can delay or facilitate biochemically directed di...

Metformin ameliorates Ox-LDL-induced foam cell formation in raw264.7 cells by promoting ABCG-1 mediated cholesterol efflux.

The accumulation of lipids in macrophages contributes to the development of atherosclerosis. Cholesterol efflux of lipid-loaded macrophages mediated by ATP binding cassette (ABC) cholesterol transport...

A Study of the Safety and Efficacy of Patients With Familial Hypercholesterolaemia Taking Colesevelam as add-on Therapy to Their Existing Medication

This study is designed to assess whether colesevelam given as third line treatment added to a maximal tolerated and stable dose of a statin and ezetimibe is able to further decrease the le...

the Change of Cholesterol Efflux Capacity and Coronary Artery Disease in Real Clinical Practice

The purpose of this study is to investigate the change of cholesterol efflux capacity in patients with coronary artery disease treated with secondary prevention drugs, and the correlation ...

Impaired HDL and Coronary Artery Disease in Anabolic Androgenic Steroid Users

Anabolic androgenic steroids (AASs) have been associated with coronary artery disease (CAD). The illicit use of these substances also leads to a remarkable decrease in high-density lipopro...

Study of High Density Lipoprotein Cholesterol (HDL-C)-Raising Mechanism of Rosuvastatin (CRESTOR™) by Quantifying the Key Steps of Reverse Cholesterol Transport (RCT)

The purpose of this study is to investigate the effect of treatment with rosuvastatin on the capacity of plasma to promote cholesterol efflux, which is the first and likely rate limiting s...

Study of Asian Patients With Hypercholesterolaemia in the UK - Rosuvastatin 5mg Versus Atorvastatin 10mg

The purpose of this study is to compare the effectiveness and safety of rosuvastatin 5mg in lowering blood cholesterol, compared to one other medicine, atorvastatin 10mg in Asian patients ...

Medical and Biotech [MESH] Definitions

The most abundant protein component of HIGH DENSITY LIPOPROTEINS or HDL. This protein serves as an acceptor for CHOLESTEROL released from cells thus promoting efflux of cholesterol to HDL then to the LIVER for excretion from the body (reverse cholesterol transport). It also acts as a cofactor for LECITHIN CHOLESTEROL ACYLTRANSFERASE that forms CHOLESTEROL ESTERS on the HDL particles. Mutations of this gene APOA1 cause HDL deficiency, such as in FAMILIAL ALPHA LIPOPROTEIN DEFICIENCY DISEASE and in some patients with TANGIER DISEASE.

An ATP binding cassette transporter, sub-family G protein that functions as a high capacity UREA exporter, transporter of STEROLS, and in the absorption and efflux of many drugs. Its efflux activity for ANTINEOPLASTIC AGENTS contributes to DRUG RESISTANCE. It functions as a homodimer and is expressed by cells in a variety of organs, as well as by NEOPLASTIC STEM CELLS.

Methods of implanting a CELL NUCLEUS from a donor cell into an enucleated acceptor cell. Often the nucleus of a somatic cell is transferred into a recipient OVUM or stem cell (STEM CELLS) with the nucleus removed. This technology may provide means to generate autologous diploid pluripotent cell for therapeutic cloning, and a model for studying NUCLEAR REPROGRAMMING in embryonic stem cells. Nuclear transfer was first accomplished with frog eggs (RANA PIPIENS) and reported in 1952.

The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.

The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
