Effects of lipoprotein lipase and statins on cholesterol uptake into heart and skeletal muscles⃞

Journal of Lipid Research, 2007
Regulation of cholesterol metabolism in cultured cells and in the liver is dependent on actions of the LDL receptor. However, nonhepatic tissues have multiple pathways of cholesterol uptake.

A Facial Foundation Model for Clinical Biomarker Prediction and Real‐World Mobile Deployment

Advanced Science, EarlyView.
MedicalFaceFound is a facial foundation model developed through three‐stage progressive pre‐training, adapting representations from general vision to facial structure and clinical phenotypes. Using a single facial image, it estimates 62 biomarkers across multiple physiological systems and supports downstream risk prediction for cardiovascular ...

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

Advanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Reducing saturated fat intake is associated with increased levels of LDL receptors on mononuclear cells in healthy men and women

Journal of Lipid Research, 1997
Studies with animal models suggest that saturated fatty acids raise low density lipoprotein (LDL)-cholesterol levels by reducing LDL receptor-mediated clearance. To examine this directly in humans, we studied the effects of lowering dietary saturated fat

Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

Advanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

Rates of low density lipoprotein uptake and cholesterol synthesis are regulated independently in the liver.

Journal of Lipid Research, 1985
The relationship between rates of hepatic sterol synthesis and rates of hepatic low density lipoprotein (LDL) uptake (clearance) was studied in animals with high (rats), low (female hamsters), and very low (male hamsters) basal rates of hepatic sterol ...

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

Advanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

Extracellular Vesicle Packaged TDP43 Derived From ECs Exacerbates Cigarette Tar‐Related Atherosclerosis Progression via Enhancing Macrophage Extracellular Traps

Advanced Science, EarlyView.
Cigarette tar triggers EC‐derived EVs carrying TDP43, which binds VDAC1 to boost MAMs, mitochondrial Ca2+ overload, and METs formation in macrophages, accelerating smoking‐related AS progression, while retinoic acid binds TDP43 to block this pathogenic cascade.

NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Regulation of hepatic LDL metabolism in the guinea pig by dietary fat and cholesterol.

Journal of Lipid Research, 1994
Studies were carried out to determine the independent and interactive effects of dietary fat and cholesterol on the regulation of hepatic apoB/E receptor expression and its relationship to hepatic cholesterol concentrations and low density lipoprotein ...
