Plasma PCSK9 preferentially reduces liver LDL receptors in mice*

open access: yesJournal of Lipid Research, 2008
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secreted protein that regulates the expression of LDL receptor (LDLR) protein. Gain-of-function mutations in PCSK9 cause hypercholesterolemia, and loss-of-function mutations result in lower ...

Redox‐Responsive Tellurium‐Bridged Covalent Organic Frameworks/PEG Composites for Targeted Therapy of Diabetic Cardiomyopathy

open access: yesAdvanced Science, EarlyView.
This study unlocks the immense potential of COF@polymer nanocomposites as a multifunctional therapeutic platform for targeted drug delivery in diabetic cardiomyopathy. Abstract Diabetic cardiomyopathy, a major complication of diabetes, is strongly associated with elevated levels of glycated hemoglobin (HbA1c) and reactive oxygen species (ROS). However,

Enhanced metabolism of LDL aggregates mediated by specific human monocyte IgG Fc receptors.

open access: yesJournal of Lipid Research, 1995
Macrophage-derived foam cells are important constituents of atheromatous lesions. In addition to the scavenger receptor pathway, uptake of immune complexed lipoproteins through IgG Fc receptors (Fc gamma receptors) represents an additional pathway of ...

Lactylation‐Driven YTHDC1 Alleviates MASLD by Suppressing PTPN22‐Mediated Dephosphorylation of NLRP3

open access: yesAdvanced Science, EarlyView.
In MASLD, YTHDC1 undergoes increased lactylation and ubiquitination, reducing its expression. AARS1 mediates lactylation at lysine 565, while disrupted binding to LDHA further promotes lactylation, suppressing YTHDC1. This downregulation enhances PTPN22 mRNA stability, leading to NLRP3 dephosphorylation and activation, which exacerbates inflammation ...

Immunohistochemical Labeling of Low-Density Lipoprotein Receptor and Scavenger Receptor Class B Type 1 Are Increased in Canine Lymphoma

open access: yesFrontiers in Veterinary Science, 2019
Altered lipid metabolism is a well-documented hallmark of neoplastic transformation and impacts disease progression. Two major lipoprotein receptors, the low-density lipoprotein receptor (LDL-R) and scavenger receptor class B, type 1 (SR-BI) are ...

Oxidized LDL triggers pro-oncogenic signaling in human breast mammary epithelial cells partly via stimulation of MiR-21. [PDF]

open access: yesPLoS ONE, 2012
Dyslipidemia and obesity are primary risk factors for the development of atherosclerosis and are also epidemiologically linked to increased susceptibility to a variety of cancers including breast cancer.

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Skeletal Muscle HSF1 Alleviates Age‐Associated Sarcopenia and Mitochondrial Function Decline via SIRT3‐PGC1α Axis

open access: yesAdvanced Science, EarlyView.
Aged HSF1 muscle‐specific knockout mice show deteriorated muscle atrophy and metabolic dysfunction, while active HSF1 overexpression improves muscle function via activating SIRT3 to deacetylate both PGC1α1 and PGC1α4, which boosts mitochondrial function and muscle hypertrophy in a fiber‐type specific manner, and induces FNDC5/Irisin for tissue ...

Apolipoprotein E and cardiovascular disease

open access: yesRevista de la Facultad de Medicina, 2006
Apolipoprotein E is a polymorphic glycoprotein who interacts with the lipoprotein receptors (LRP-Receptor Related Protein) and the receptors for low density lipoproteins of (LDL receptors). When lipoproteins bring up the receptors begins lipids captation
