Microanalysis of cardiolipin in small biopsies including skeletal muscle from patients with mitochondrial disease

open access: yesJournal of Lipid Research, 1999
Cardiolipin is a specific mitochondrial phospholipid that is present in mammalian tissues in low concentration. To measure cardiolipin in small biopsies from patients with mitochondrial disease, we developed a new technique that can detect subnanomolar ...

PON2 Deficiency Leads to Increased Susceptibility to Diet-Induced Obesity. [PDF]

open access: yes, 2019
(1) Background: Paraoxonase 2 (PON2) is a ubiquitously expressed protein localized to endoplasmic reticulum and mitochondria. Previous studies have shown that PON2 exhibits anti-oxidant and anti-inflammatory functions, and PON2-deficient (PON2-def) mice ...

Shotgun lipidomics of cardiolipin molecular species in lipid extracts of biological samples

open access: yesJournal of Lipid Research, 2006
Cardiolipin is a prominent component of the mitochondrial inner membranes contributing to the regulation of multiple discrete mitochondrial functions. Here, we extend shotgun lipidomics to identify and quantitate cardiolipin molecular species directly ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models

open access: yesAdvanced Functional Materials, EarlyView.
This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Nature‐Inspired Surface Modification Strategy Reverses the Autophagic Flux Impairment of Mitochondrial Transplantation for Attenuating Ischemic Strokes

open access: yesAdvanced Science, EarlyView.
The functionalized starch modifies the mitochondrial surface and encapsulates resveratrol into the cavity of helices, facilitating a novel mitochondrial transplantation platform (MLSR). Upon internalization in recipient cells, MLSR triggers mitophagy and maintains positive autophagic flux through RIP1/RIP3 pathway inhibition.

Cytochrome c: Surfing Off of the Mitochondrial Membrane on the Tops of Complexes III and IV [PDF]

open access: yes, 2019
The proper arrangement of protein components within the respiratory electron transport chain is nowadays a matter of intense debate, since altering it leads to cell aging and other related pathologies.

PAF Triggered Pyroptotic NETosis Aggravates Myocardial Ischemia/Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Platelet activating factor (PAF) secreted by cardiomyocytes during MI/R, drives NETs formation and subsequent NETosis. PAF/NETosis signaling activation is an initiative and causal factor in driving MI/R injury. This study identifies dapagliflozin as a potent NETosis inhibitor, and demonstrates that manipulating PAF‐NETosis signal by dapagliflozin or ...

Uncovering the mechanisms of host mitochondrial cardiolipin release in syphilis: Insights from human microvascular endothelial cells

open access: yesInternational Journal of Medical Microbiology
The release of host mitochondrial cardiolipin is believed to be the main factor that contributes to the production of anti-cardiolipin antibodies in syphilis.

Phosphatidic Acid‐TRIM59‐Olig2 Signaling Couples Metabolic Dysfunction to Myelination Failure in PWMI

open access: yesAdvanced Science, EarlyView.
PA accumulates after hypoxic‐ischemic injury and stabilizes the E3 ligase TRIM59 in OPCs. Stabilized TRIM59 enhances ubiquitination and degradation of Olig2, blocking differentiation and causing hypomyelination in PWMI. Modulating PA synthesis restores Olig2 levels, improves myelination, and ameliorates behavioral deficits, defining a metabolically ...

Cross-species complementation of bacterial- and eukaryotic-type cardiolipin synthases

open access: yesMicrobial Cell, 2017
The glycerophospholipid cardiolipin is a unique constituent of bacterial and mitochondrial membranes. It is involved in forming and stabilizing high molecular mass membrane protein complexes and in maintaining membrane architecture.
