Increased hepatobiliary and fecal cholesterol excretion upon activation of the liver X receptor is independent of ABCA1 [PDF]

, 2002
The ATP-binding cassette transporter ABCA1 is essential for high density lipoprotein (HDL) formation and considered rate-controlling for reverse cholesterol transport. Expression of the Abca1 gene is under control of the liver X receptor (LXR).

High levels of serum cholesterol increase the risk of developing vessel co‐opting tumors in colorectal cancer liver metastases

The FEBS Journal, EarlyView.
High serum cholesterol is linked to colorectal cancer liver metastases (CRCLM) subtypes with poor survival (replacement pattern). Levels of cholesterol under 4 mmol·L−1 correlated with better survival and a desmoplastic pattern subtype. Furthermore, in vivo PCSK9 inhibitor evolocumab, which lowers cholesterol, reduced liver metastases.

Cholesterol-sensing liver X receptors stimulate Th2-driven allergic eosinophilic asthma in mice [PDF]

, 2016
Introduction: Liver X receptors (LXRs) are nuclear receptors that function as cholesterol sensors and regulate cholesterol homeostasis. High cholesterol has been recognized as a risk factor in asthma; however, the mechanism of this linkage is not known.

Purification and ATPase Activity of Human ABCA1

Journal of Biological Chemistry, 2006
ATP-binding cassette protein A1 (ABCA1) plays a major role in cholesterol homeostasis and high density lipoprotein metabolism. Apolipoprotein A-I binds to ABCA1 and cellular cholesterol and phospholipids, mainly phosphatidylcholine, are loaded onto apoA-I to form pre-beta high density lipoprotein (HDL).

Apolipoprotein A-I activates Cdc42 signaling through the ABCA1 transporter

Journal of Lipid Research, 2006
It has been suggested that the signal transduction initiated by apolipoprotein A-I (apoA-I) activates key proteins involved in cholesterol efflux. ABCA1 serves as a binding partner for apoA-I, but its participation in apoA-I-induced signaling remains ...

Genetic risk variants implicate impaired maintenance and repair of periodontal tissues as causal for periodontitis—A synthesis of recent findings

Periodontology 2000, EarlyView.
AbstractPeriodontitis is a complex inflammatory disease in which the host genome, in conjunction with extrinsic factors, determines susceptibility and progression. Genetic predisposition is the strongest risk factor in the first decades of life. As people age, chronic exposure to the periodontal microbiome puts a strain on the proper maintenance of ...

Apolipoprotein E: from cardiovascular disease to neurodegenerative disorders. [PDF]

, 2016
Apolipoprotein (apo) E was initially described as a lipid transport protein and major ligand for low density lipoprotein (LDL) receptors with a role in cholesterol metabolism and cardiovascular disease.

Methods for Monitoring ABCA1-Dependent Sterol Release [PDF]

, 2017
Releasing sterols to the extracellular milieu is an important part of sterol homeostasis in cells and in the body. ATP-binding cassette transporter A1 (ABCA1) plays an essential role in cellular phospholipid and sterol release to lipid-free or lipid-poor apolipoprotein A-I (apoA-I), the major apolipoprotein in high-density lipoprotein (HDL), and ...

ABCA1 redistributes membrane cholesterol independent of apolipoprotein interactions

Journal of Lipid Research, 2003
ATP binding cassette transporter A1 (ABCA1) mediates the transport of phospholipids and cholesterol from cells to lipid-poor HDL apolipoproteins. Cholesterol loading of cells induces ABCA1, implicating cholesterol as its major physiologic substrate.

Internalization of Exogenous Myelin by Oligodendroglia Promotes Lineage Progression

Glia, Volume 74, Issue 3, March 2026.
Oligodendroglia internalize extracellular myelin debris in vitro and in vivo. Internalized myelin modulates lipid metabolism and lipid droplet formation. Myelin‐derived signals promote oligodendroglial proliferation and lineage progression. ABSTRACT Oligodendrocytes, traditionally recognized for their role in central nervous system myelination, have ...
