Structure of a mitochondrial ATP synthase with bound native cardiolipin

open access: yeseLife, 2019
The mitochondrial ATP synthase fuels eukaryotic cells with chemical energy. Here we report the cryo-EM structure of a divergent ATP synthase dimer from mitochondria of Euglena gracilis, a member of the phylum Euglenozoa that also includes human parasites.

Characteristics and Outcomes of Male Participants in a Multicenter Longitudinal Australian Study Cohort

open access: yesArthritis Care &Research, EarlyView.
Objective The aim of this study was to determine the differences in demographic, serologic, and clinical characteristics between male and female patients with systemic sclerosis (SSc) in an Australian cohort. Methods This was a retrospective observational study using data from the Australian Scleroderma Cohort Study.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

open access: yesAdvanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

open access: yesAdvanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

open access: yesAdvanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

Targeting Lipopolysaccharide Transport Induces Membrane Lipid Remodeling and Sensitizes Acinetobacter baumannii to Colistin Treatment

open access: yesAdvanced Science, EarlyView.
This study identifies C4 as a lead inhibitor of the Lpt system. Notably, C4 potentiates colistin activity by disrupting LPS transport and remodeling phospholipid homeostasis, revealing a functional interplay between the Lpt and Mla systems. These findings establish a mechanistic link between Lpt inhibition and membrane lipid remodeling, positioning Lpt–

Fatty acyl availability modulates cardiolipin composition and alters mitochondrial function in HeLa cells

open access: yesJournal of Lipid Research, 2021
The molecular assembly of cells depends not only on the balance between anabolism and catabolism but to a large degree on the building blocks available in the environment. For cultured mammalian cells, this is largely determined by the composition of the

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...
