Neutral glycolipids of the filamentous fungus Neurospora crassa:altered expression in plant defensin-resistant mutants

open access: yesJournal of Lipid Research, 2005
To defend themselves against fungal pathogens, plants produce numerous antifungal proteins and peptides, including defensins, some of which have been proposed to interact with fungal cell surface glycosphingolipid components.

Kinetic modelling of sterol transport between plasma membrane and endo-lysosomes based on quantitative fluorescence and X-ray imaging data

open access: yesFrontiers in Cell and Developmental Biology, 2023
Niemann Pick type C1 and C2 (NPC1 and NPC2) are two sterol-binding proteins which, together, orchestrate cholesterol transport through late endosomes and lysosomes (LE/LYSs).

Niemann-Pick type C proteins promote microautophagy by expanding raft-like membrane domains in the yeast vacuole

open access: yeseLife, 2017
Niemann-Pick type C is a storage disease caused by dysfunction of NPC proteins, which transport cholesterol from the lumen of lysosomes to the limiting membrane of that compartment.

Solid phase extraction of β-sitosterol and α-tocopherol from sunflower oil deodorizer distillate using desilicated zeolite

open access: yesGrasas y Aceites, 2020
In this study, the efficiency of using zeolite-based adsorbents in a solid phase extraction (SPE) procedure of α-tocopherol and β-sitosterol isolation from Sunflower Oil Deodorizer Distillate (SuDOD) with­out pre-treatment was investigated.

Chemical Composition and Antioxidant Activity of Lipids from Ficus Carica l. Fruits

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2023
Samples of oils from seven types of Ficus carica L. fruits from Algeria were investigated through determinations of their chemical characteristics, quantifying sterols and tocopherols, and analysis of the fatty acids profiles using gas chromatography ...

Metabolism and Biological Activities of 4-Methyl-Sterols

open access: yesMolecules, 2019
4,4-Dimethylsterols and 4-methylsterols are sterol biosynthetic intermediates (C4-SBIs) acting as precursors of cholesterol, ergosterol, and phytosterols.

Green Microalgae Strain Improvement for the Production of Sterols and Squalene

open access: yesPlants, 2021
Sterols and squalene are essential biomolecules required for the homeostasis of eukaryotic membrane permeability and fluidity. Both compounds have beneficial effects on human health. As the current sources of sterols and squalene are plant and shark oils,

The Cerebrospinal Fluid Profile of Cholesterol Metabolites in Parkinson’s Disease and Their Association With Disease State and Clinical Features

open access: yesFrontiers in Aging Neuroscience, 2021
Disordered cholesterol metabolism is linked to neurodegeneration. In this study we investigated the profile of cholesterol metabolites found in the cerebrospinal fluid (CSF) of Parkinson’s disease (PD) patients. When adjustments were made for confounding

Identification of twenty-three mutations in fission yeast Scap that constitutively activate SREBP*

open access: yesJournal of Lipid Research, 2008
The endoplasmic reticulum membrane protein SREBP cleavage-activating protein (Scap) senses sterols and regulates activation of sterol-regulatory element binding proteins (SREBPs), membrane-bound transcription factors that control lipid homeostasis in ...

Sterols from Thai Marine Sponge Petrosia (Strongylophora) sp. and Their Cytotoxicity

open access: yesMarine Drugs, 2017
Eight new sterols (1–5 and 11–13), together with eight known compounds (6–10 and 14–16) were isolated from marine sponge Petrosia sp. The structures of these compounds were elucidated on the basis of extensive spectroscopic analysis.
