Biomembranal Myristoyl-Phosphatidylcholine as a Potential Target of the Cell Injury Activity of Vitamin D Decomposition Products in Eukaryotic Cells

open access: yesFrontiers in Bioscience-Landmark
Background: Vitamin D decomposition products target a myristic acid sidechain of the predominant glycerophospholipid constructed in the biomembranes of Helicobacter pylori, causing gastric cancer in humans, and disrupt the membrane ...

Use of 31PNMR spectroscopy to follow the time course of phosphatidylcholine chemical synthesis.

open access: yesJournal of Lipid Research, 1985
31PNMR spectroscopy is shown to be useful for studying the chemical synthesis of phosphatidylcholine from phosphatidic acid and choline. Sharp, well-resolved resonances were obtained by chelating multivalent cations, thereby enabling quantitation of ...

Anti-inflammatory Effects of Phosphatidylcholine [PDF]

open access: yesJournal of Biological Chemistry, 2007
We recently showed that mucus from patients with ulcerative colitis, a chronic inflammatory disorder of the colon, is characterized by a low level of phosphatidylcholine (PC) while clinical studies reveal that therapeutic addition of PC using slow release preparations is beneficial. The positive role of PC in this disease is still elusive.

Structural library and visualization of endogenously oxidized phosphatidylcholines using mass spectrometry-based techniques

open access: yesNature Communications, 2021
Oxidized phosphatidylcholines (oxPCs) are a structurally diverse class of lipids associated with various diseases. Here, the authors use mass spectrometry to construct a spectral library of 465 oxPCs and subsequently profile oxPCs formed during ...

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Increased dietary methionine, lysine and histidine supply modulated the heat stress-induced metabolic remodeling of dairy cows

open access: yesFrontiers in Animal Science
Increasing dietary Met, Lys, and His supply without increasing the dietary protein content was reported to partially alleviate the productive and physiological impact of heat stress. Nevertheless, the metabolic pathways involved are yet to be identified.

Mass spectrometry of the phosphatidyl amino alcohols: detection of molecular species and use of low voltage spectra and metastable scanning in the elucidation of structure

open access: yesJournal of Lipid Research, 1972
The basic fragmentation mechanisms occurring in the mass spectra of the phosphatidylcholines have been described previously, and evidence was adduced to show that many of the more abundant ions are related by electron impact-induced processes.

From Cell‐Derived Vesicles to Hybrid Nanovectors: Biological Membranes as Functional Blueprints for Gene Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Biologically derived and hybrid nonviral nanovectors are examined as distinct but convergent design approaches. Integrating synthetic components with biologically functionalized membranes allows efficient interactions with complex cellular environments.

Advent of Novel Phosphatidylcholine-Associated Nonsteroidal Anti-Inflammatory Drugs with Improved Gastrointestinal Safety

open access: yesGut and Liver, 2013
The mucosa of the gastrointestinal (GI) tract exhibits hydrophobic, nonwettable properties that protect the underlying epithelium from gastric acid and other luminal toxins.
