Lipid Exchangers: Cellular Functions and Mechanistic Links With Phosphoinositide Metabolism

open access: yesFrontiers in Cell and Developmental Biology, 2020
Lipids are amphiphilic molecules that self-assemble to form biological membranes. Thousands of lipid species coexist in the cell and, once combined, define organelle identity.

The metastasis inducer CCN1 (CYR61) activates the fatty acid synthase (FASN)-driven lipogenic phenotype in breast cancer cells [PDF]

open access: yes, 2016
The angiogenic inducer CCN1 (Cysteine-rich 61, CYR61) is differentially activated in metastatic breast carcinomas. However, little is known about the precise mechanisms that underlie the pro-metastatic actions of CCN1. Here, we investigated the impact of

Urinary Bladder Sterols.

open access: yesExperimental Biology and Medicine, 1957
Summary1. Urinary bladders of many species were analyzed for cholesterol and “fast-acting” (δ7) sterol. Rodents showed the highest content of (δ7) sterol, the dog an intermediate level, and livestock very little. In rodents and in the dog 60-84% of the δ7-sterol was 7-dehydrocholesterol. All bladder sterol was unesterified. 2. The sterols were found to

Smart Nanoparticles Disrupting Energy Supply through Triple Mechanisms to Kill Tumors via Dual Disruption of Mitochondria and Lysosomes

open access: yesAdvanced Science, EarlyView.
This study introduces a biomimetic nanoplatform (MTCA@C) designed for precise cancer therapy. It targets mitochondria to induce dysfunction through photodynamic activation, while concurrently blocking mitophagy via lysosomal alkalinization. The platform further triggers methuosis, resulting in tumor cell death through vacuolization and energy pathway ...

NUDT21‐mediated Alternative Polyadenylation of CDK19 Reprograms Cholesterol Biosynthesis to Drive Colorectal Cancer Progression

open access: yesAdvanced Science, EarlyView.
NUDT21 is overexpressed in colorectal cancer tumors and promotes colorectal cancer progression. NUDT21 promotes the production of a cyclin‐dependent kinase 19 (CDK19) mRNA isoform with a long 3′ UTR, which enhances cytoplasmic export and translation. Truncation of the CDK19 long 3′ UTR phenocopies NUDT21 loss, recapitulating the defects in cholesterol ...

High-performance liquid chromatography analysis of phytosterols in Panax ginseng root grown under different conditions

open access: yesJournal of Ginseng Research, 2018
Background: The Panax ginseng plant is used as an herbal medicine. Phytosterols of P. ginseng have inhibitory effects on inflammation-related factors in HepG2 cells. Methods: Phytosterols (e.g., stigmasterol and β-sitosterol) in the roots of P.

Flagellar membrane association via interaction with lipid rafts [PDF]

open access: yes, 2009
The eukaryotic flagellar membrane has a distinct composition from other domains of the plasmalemma. Our work shows that the specialized composition of the trypanosome flagellar membrane reflects increased concentrations of sterols and saturated fatty ...

CD147/Basigin: From Integrative Molecular Hub to Translational Therapeutic Target

open access: yesAdvanced Science, EarlyView.
This review conceptualizes CD147 as a fundamental “Energy‐Structure Coupler,” physically bridging metabolic flux (via MCTs) with morphogenetic plasticity (via integrins/MMPs) to drive cancer, infection, and autoimmunity. Addressing the “specificity paradox” that limits current translation, the authors chart a strategic roadmap—spanning logic‐gated ...

Gas Chromatographic Determination and Method Validation of Stigmasterol, Β-Sitosterol, Campesterol and Brassicasterol Contents of Turkish Cottonseed Oil Samples

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2017
Plant sterols are important agricultural products for human health and consequently, for nutrition industries. In the present study, free sterol contents of crude Turkish cottonseed oil samples have been determined in a single analytical run by using a ...

Synergistic Anti-Candida Activity of Bengazole A in the Presence of Bengamide A †. [PDF]

open access: yes, 2019
Bengazoles A⁻G from the marine sponge Jaspis sp. exhibit potent in vitro antifungal activity against Candida spp. and other pathogenic fungi. The mechanism of action (MOA) of bengazole A was explored in Candida albicans under both liquid culture and ...
