Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Altered Peripheral Blood Mononuclear Cell (PBMC) Mitochondrial Coupling and Complex IV Respiration in Severe Aortic Stenosis Before and After Transcatheter Aortic Valve Replacement (TAVR)

Journal of Cardiovascular Development and Disease
Background: Circulating peripheral blood mononuclear cell (PBMC) mitochondrial respiration is impaired in heart failure and transplanted patients.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Oxidative Stress and Mitochondria Are Involved in Anaphylaxis and Mast Cell Degranulation: A Systematic Review

Antioxidants
Anaphylaxis, an allergic reaction caused by the massive release of active mediators, can lead to anaphylactic shock (AS), the most severe and potentially life-threatening form of anaphylactic reaction.

Mitochondrial calcium regulation during and following contractions in skeletal muscle

Journal of Physical Fitness and Sports Medicine, 2018
In skeletal muscle, resting cytosolic Ca2+ concentration ([Ca2+]cyto) homeostasis is exquisitely regulated by Ca2+ transport across the sarcolemmal, mitochondrial and sarcoplasmic reticulum (SR) membranes.

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

FEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Mitochondrial Dysfunction and Oxidative Stress: Emerging Insights in Muscle and Cardiovascular Disease Mechanisms

Antioxidants
Beyond their role as the “energy powerhouse” of the cell, mitochondria have emerged as essential actors in molecular signaling and determination of cellular fate, particularly through the production of reactive oxygen species (ROS) [...]
