Specific perception of ergosterol by plant cells [PDF]

, 2003
Ergosterol (a fungal membrane component) induced modification of proton fluxes and membrane yperpolarization in motor cells of Mimosa pudica. These reactions appear specific since they were not induced by the other sterols tested.

Controlled delivery of membrane proteins to artificial lipid bilayers by nystatin-ergosterol modulated vesicle fusion

, 2006
The study of ion channels and other membrane proteins and their potential use as biosensors and drug screening targets require their reconstitution in an artificial membrane.

Ergosterol from the soilborne fungus Ganoderma boninense. [PDF]

, 2011
Ergosterol is the main component of the fungal membrane and is not found in plants or other microbial cells. Therefore, it can be a useful biomarker for the quantification of fungal biomass.

Expression pattern, subcellular localization of Aspergillus oryzae ergosterol synthases, and their effects on ergosterol and fatty acid metabolism

Applied and Environmental Microbiology
Ergosterol is an important component of fungal cell membranes and participates in the regulation of its fluidity, permeability, and material transport. In our study, we found that the ergosterol biosynthesis pathway in Aspergillus oryzae is more complex ...

Ergosterol Peroxide: a Fungal Artefact [PDF]

Nature, 1967
ALTHOUGH the isolation of ergosterol peroxide from the extracts of several different fungi has been reported1–4, the question of its authenticity as a metabolite in these cases does not seem to have been raised. In the present case, the peroxide was found to be present in extracts of sporophores of Piptoporus betulinus or of Daedalea quercina.

Unraveling Unique Effect of Ergosterol on Lipid Membranes, and What We Can Do with the Future STS [PDF]

Structural Dynamics
Ergosterol, a critical component of fungal membranes, has traditionally been thought to influence membrane properties in much the same way as cholesterol because of their similar structures.

Water- and air-distributed conidia differ in sterol content and cytoplasmic microviscosity

, 2010
Airborne and waterborne fungal spores were compared with respect to cytoplasmic viscosity and the presence of ergosterol. These parameters differed markedly between the two spore types and correlated with spore survival.

Δ8(9),22-Ergostadiene-3β-ol, an ergosterol precursor accumulated in wild-type and mutants of yeast

Journal of Lipid Research, 1972
Whereas wild-type strains of Saccharomyces cerevisiae can synthesize up to 7% dry weight of ergosterol, a polyene-resistant mutant has been obtained which produces no ergosterol. Instead, a C-28 methyl sterol is produced, and it has been identified as Δ8(

Antioxidant Potential of Ergosterol–Phospholipid Liposomes with Thymus serpyllum Extract

Proceedings
The antioxidant activity of ergosterol–phospholipid liposomes with chemically characterized, encapsulated wild thyme (Thymus serpyllum) extract was examined. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)

Synthesis and Cytotoxic Activity of Novel Ergosterol Peroxide Derivatives with Acrylate or Propionate Side Chain

Natural Product Communications, 2022
A series of novel ergosterol peroxide derivatives with acrylate or propionate side chain were synthesized. All compounds 3a-n were evaluated for their cytotoxicity against four kinds of human carcinoma cell lines (HepG2, MCF-7, HCT-116, and A549).
