Isoproterenol decreases LDL receptor expression in rat adipose cells: activation of cyclic AMP-dependent proteolysis

Journal of Lipid Research, 1996
The low density lipoprotein (LDL) receptor is part of a family of proteins that mediate the uptake of lipoproteins into cells. In this paper we have demonstrated the over-expression in E. coli of a rat LDL receptor fusion protein that contains the region

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A potential complication in the use of monoclonal antibodies: inhibition of apoB-mediated receptor binding by an anti-apoE antibody.

Journal of Lipid Research, 1989
Monoclonal antibody (Mab) 1D7 is specific for human apolipoprotein (apo) E and blocks binding of lipid-associated apoE to the low density lipoprotein (LDL) receptor. We report here that 1D7 can also block the binding of apoE-free LDL to the LDL receptor.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Macrophage-mediated oxidation of extracellular low density lipoprotein requires an initial binding of the lipoprotein to its receptor.

Journal of Lipid Research, 1994
Cells of the arterial wall including macrophages were shown to oxidize low density lipoprotein (LDL) in vitro. Upon incubation of LDL with J-774.A1 macrophage-like cell line for 18 h in the presence of 1 microM CuSO4, extensive macrophage-mediated ...

IV Thrombolysis Facilitates Interventional Reperfusion in Non‐Cardioembolic but Not Cardioembolic Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Intravenous thrombolysis (IVT) before thrombectomy for ischemic stroke may alter clot structure and procedural performance. We investigated how IVT relates to thrombectomy metrics across stroke etiologies. Methods We performed a time‐to‐event analysis of consecutive patients with anterior circulation large vessel occlusion (acLVO ...

Lipoprotein assembly and function in an evolutionary perspective

Biomolecular Concepts, 2010
Circulatory fat transport in animals relies on members of the large lipid transfer protein (LLTP) superfamily, including mammalian apolipoprotein B (apoB) and insect apolipophorin II/I (apoLp-II/I).

Low density lipoprotein from humans supplemented with n-3 fatty acids depresses both LDL receptor activity and LDLr mRNA abundance in HepG2 cells.

Journal of Lipid Research, 1992
Fish oil supplementation in humans is often associated with an expanded low density lipoprotein (LDL) pool that is not thought to reflect increased production.

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Factors regulating the activities of the low density lipoprotein receptor and the scavenger receptor on human monocyte-macrophages.

Journal of Lipid Research, 1981
Improved techniques of cell isolation resulted in 90 to 100 million monocytes from a single donor. Addition of low density lipoprotein (LDL) to to cultures of these cells resulted in the down regulation of LDL receptor activity.
