LDL Receptors in Keratinocytes

Journal of Investigative Dermatology, 1992
The presence of sufficient amounts of cholesterol in the epidermis is necessary for proper functioning of plasma membranes in the viable epidermal cell layers and also for the barrier quality of lipid intercellular bilayers of the stratum corneum. Cholesterol can be generated by local epidermal synthesis, or imported from the circulation as low-density

Compensated endocytosis of LDL by hamster cells co-expressing the two distinct mutant LDL receptors defective in endocytosis and ligand binding

Journal of Lipid Research, 1999
The low density lipoprotein receptor (LDLR) regulates the plasma cholesterol level by mediating endocytosis of LDL. We established stable hamster cell lines expressing two LDLRs with distinct functional defects, i.e., endocytosis and ligand binding.

Thematic review series: The Immune System and Atherogenesis. Recent insights into the biology of macrophage scavenger receptors

Journal of Lipid Research, 2005
Scavenger receptors were originally defined by their ability to bind and internalize modified lipoproteins. Macrophages express at least six structurally different cell surface receptors for modified forms of LDL that contribute to foam cell formation in

Macrophage-derived factors increase low density lipoprotein uptake and receptor number in cultured human liver cells.

Journal of Lipid Research, 1991
Recent evidence suggests the possibility that macrophages can influence lipoprotein metabolism. Therefore we investigated the ability of cultured macrophages to alter low density lipoprotein (LDL) uptake in a human liver cell line (HepG2).

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.

Effect of neoadjuvant chemotherapy on low-density lipoprotein (LDL) receptor and LDL receptor-related protein 1 (LRP-1) receptor in locally advanced breast cancer

Brazilian Journal of Medical and Biological Research, 2012
Low-density lipoprotein (LDL) receptors are overexpressed in most neoplastic cell lines and provide a mechanism for the internalization and concentration of drug-laden nanoemulsions that bind to these receptors.

Hepatic triglyceride lipase promotes low density lipoprotein receptor-mediated catabolism of very low density lipoproteins in vitro

Journal of Lipid Research, 1999
We demonstrate here that hepatic triglyceride lipase (HTGL) enhances VLDL degradation in cultured cells by a LDL receptor-mediated mechanism. VLDL binding at 4°C and degradation at 37°C by normal fibroblasts was stimulated by HTGL in a dose-dependent ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Identification of lipoprotein-binding proteins in rat liver Golgi apparatus membranes

Journal of Lipid Research, 1988
The low density lipoprotein (LDL) receptor has been shown to be a plasma membrane glycoprotein responsible for the cellular binding and endocytosis of plasma lipoproteins.

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 ...
