MetabolomicsOPA1 promotes ferroptosis by augmenting mitochondrial ROS and suppressing an integrated stress response

Ferroptosis, an iron-dependent form of nonapoptotic cell death mediated by lipid peroxidation, has been implicated in the pathogenesis of multiple diseases. Subcellular organelles play pivotal roles in the regulation of ferroptosis, but the mechanisms underlying the contributions of the mitochond...

MetabolomicsExercise-generated β-aminoisobutyric acid (BAIBA) reduces cardiomyocytes metabolic stress and apoptosis caused by mitochondrial dysfunction through the miR-208b/AMPK pathway

OBJECTIVE: To explore the cardioprotective effects of exercise-derived β-aminoisobutyric (BAIBA) on cardiomyocyte apoptosis and energy metabolism in a rat model of heart failure (HF).

METHODS: In male Sprague-Dawley rats (8-week-old), myocardial infarction ...

MetabolomicsDeficient Endoplasmic Reticulum-Mitochondrial Phosphatidylserine Transfer Causes Liver Disease
Non-alcoholic fatty liver is the most common liver disease worldwide. Here, we show that the mitochondrial protein mitofusin 2 (Mfn2) protects against liver disease. Reduced Mfn2 expression was detected in liver biopsies from patients with non-alcoholic steatohepatitis (NASH). Moreover, reduced Mfn2...

MetabolomicsSystem-wide analysis of short-term response to high temperature in Pinus radiata

Pinus radiata seedlings, the most widely planted pine species in the world, were exposed to temperatures within a range mimicking future scenarios based on current models of heat increase. The short-term heat response in P. radiata was studied in detail by exploring the metabolo...

ProteomicsACONITASE 3 is part of the ANAC017 transcription factor-dependent mitochondrial dysfunction response
Mitochondria are tightly embedded within metabolic and regulatory networks that optimize plant performance in response to environmental challenges. The best-known mitochondrial retrograde signaling pathway involves stress-induced activation of the transcription factor NAC DOMAIN CONTAINING PROTEIN 1...

TranscriptomicsATFS-1 mediates a protective transcription program during mitochondrial stress
ATFS-1 has been shown to regulate transcription of mitochondrial chaperone genes such as mtHsp70/hsp-6 and hsp-60 in response to mitocondrial stress. To identify the entire ATFS-1-mediated response, we compared the transcript profiles from wild-type and atfs-1(tm4525) worms raised in the absence and...

MetabolomicsGenetic Ablation of Sfxn5 Induces Mitochondrial Dysfunction and Precipitates Lethal Metabolic Crisis in Mice
Mitochondrial disorders frequently manifest with life-threatening hepatic metabolic crises. Using a global Sfxn5-knockout mouse model, we investigated the systemic consequences of disrupting this mitochondrial inner-membrane transporter through integrated biochemical, metabolomic, histological, and ...

MetabolomicsChronic sleep loss sensitizes Drosophila melanogaster to nitrogen stress

Chronic sleep loss profoundly impacts metabolic health and shortens lifespan, but studies of the mechanisms involved have focused largely on acute sleep deprivation. To identify metabolic consequences of chronically reduced sleep, we conducted unbiased metabolomics on heads of three adult Drosoph...

MetabolomicsMuscle metabolic resilience and enhanced exercise adaptation by Esr1-induced remodeling of mitochondrial cristae-nucleoid architecture in males

Reduced estrogen action is associated with obesity and insulin resistance. However, the cell and tissue-specific actions of estradiol in maintaining metabolic health remain inadequately understood, especially in men. We observed that skeletal muscle ESR1/Esr1 (encodes estrogen receptor α) is posi...

MetabolomicsModulation of liver metabolism and gut microbiota by Alhagi-honey alleviated heat stress-induced liver damage

Alhagi-honey (AH) is a well-established traditional ethnic medicine with advantageous effects against diarrhea and headaches. We aim to explore the preventive effect of AH on liver damage induced by heat stress (HS) and its underlying mechanism. HS models were established by thermostat, and mice ...
