Sterol Metabolism Differentially Contributes to Maintenance and Exit of Quiescence
Frontiers in Cell and Developmental Biology, 2022 Nutrient starvation initiates cell cycle exit and entry into quiescence, a reversible, non-proliferative state characterized by stress tolerance, longevity and large-scale remodeling of subcellular structures.

Microbial Test-System for Screening of Inhibitors of Sterol Biosynthesis
Антибиотики и Химиотерапия, 2020 New effective economic microbial test-system for screening of microbial metabolites, that are inhibitors of sterol biosynthesis, is proposed. It is based on cultivation of fungal strain Acremonium fusidioides (former Fusidium coccineum), that produces ...

Functional analysis of two sterol regulatory element binding proteins in Penicillium digitatum. [PDF]
PLoS ONE, 2017 The sterol regulatory element binding proteins (SREBPs) are key regulators for sterol homeostasis in most fungi. In the citrus postharvest pathogen Penicillium digitatum, the SREBP homolog is required for fungicide resistance and regulation of CYP51 ...

Plant Growth Retardants as Inhibitors of Sterol Biosynthesis in Tobacco Seedlings [PDF]
Plant Physiology, 1974 Three plant-growth retardants 2'-isopropy1-4'-(trimethylammonium chloride)-5-methylphenylpiperidine carboxylate (Amo 1618), beta-chloroethyltrimethylammonium chloride, and tributyl-2, 4-dichlorobenzylphosphonium chloride were tested for their effects on sterol production in, and growth of tobacco (Nicotiana tabacum) seedlings.

Plant sterol metabolism with emphasis on glycoalkaloid biosynthesis in potato [PDF]
, 2007 Glycoalkaloids are secondary metabolites present within species of the family Solanaceae. They are toxic to humans and animals, and it is important to keep the levels in potato (Solanum tuberosum L.) tubers below the safe limit for consumption ...

Dissecting cholesterol and phytosterol biosynthesis via mutants and inhibitors
, 2021 Plants stand out among eukaryotes due to the large variety of sterols and sterol derivatives that they can produce. These metabolites not only serve as critical determinants of membrane structures, but also act as signaling molecules, as growth ...

Weakening the nuclear envelope: Lamin B receptor in melanoma metastasis
Molecular Oncology, EarlyView.LBR‐driven nuclear fragility supports melanoma invasion. A: Melanocyte presents low LBR (Lamin B Receptor) levels, maintaining nuclear integrity and lamina‐chromatin tethering. B: During malignant progression, upregulation of LBR clusters at the INM (Inner Nuclear Membrane) during confined migration causes local lamina weakening and cholesterol ...

Microbial model of Halobacterium salinarum for screening inhibitors of sterol biosynthesis
Антибиотики и Химиотерапия, 2020 A highly effective and simple microbial test system for screening inhibitors of sterol biosynthesis (ISB) is described. The system is based on cultivation of the bacterial strain Halobacterium salinarum (former Halobacterium halobium), that possesses ...
