Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS 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.

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

open access: yesJournal 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 ...

Importance of Estrogen Receptors in Hepatic LDL Receptor Regulation

open access: yes, 1997
Treatment with pharmacological doses of estrogen is the most potent way to stimulate hepatic LDL receptor expression in vivo. The mechanism for this effect is unclear, in part because of difficulties in inducing this stimulation in vitro.

Effects of oxidized low density lipoprotein, lipid mediators and statins on vascular cell interactions [PDF]

open access: yes, 1999
The integrin heterodimer CD11b/CD18 (alpha M beta 2, Mac-1, CR3) expressed on monocytes or polymorphonuclear leukocytes (PMN) is a receptor for iC3b, fibrinogen, heparin, and for intercellular adhesion molecule (ICAM)-1 on endothelium, crucially ...

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

open access: yesFEBS 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.

Identification and properties of the proline664-leucine mutant LDL receptor in South Africans of Indian origin.

open access: yesJournal of Lipid Research, 1992
The incidence of familial hypercholesterolemia (FH) is high among South African Indians. The proline664-leucine low density lipoprotein (LDL)-receptor mutation was detected in four apparently unrelated Indian FH families in South Africa.

Endocytosis of the ASGP receptor H1 is reduced by mutation of tyrosine-5 but still occurs via coated pits [PDF]

open access: yes, 1991
The clustering of plasma membrane receptors in clathrin-coated pits depends on determinants within their cytoplasmic domains. In several cases, individual tyrosine residues were shown to be necessary for rapid internalization.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS 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.

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

open access: yesJournal 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.

Anàlisi de l'expressió de NOR-1 en les cèl·lules musculars llises i de la seva implicació en la proliferació cel·lular [PDF]

open access: yes, 2004
[cat] Dado que las células musculares lisas vasculares (CMLV) juegan un papel clave en el desarrollo de la aterosclerosis, conocer los genes que regulan la proliferación y migración de estas células pude conducir a encontrar nuevas dianas farmacológicas ...
