Geometric instability catalyzes mitochondrial fission

Molecular Biology of the Cell, 2019
The mitochondrial membrane undergoes extreme remodeling during fission. While a few membrane-squeezing proteins are recognized as the key drivers of fission, there is a growing body of evidence that strongly suggests that conical lipids play a critical role in regulating mitochondrial morphology and fission.

Microbial metabolite indole‐3‐propionic acid preserves astrocytic mitochondrial mitofusin 2 to limit neuroinflammation after traumatic brain injury

Interdisciplinary Medicine, EarlyView.
Following traumatic brain injury, indole‐3‐propionic acid (IPA) directly targets the aryl hydrocarbon receptor on astrocytes in the peri‐lesional cortex; this suppresses interferon regulatory factor 1‐driven transcription of the E3 ubiquitin ligase RFFL (ring finger and FYVE‐like domain containing E3 ubiquitin protein ligase).

TFAM promotes mitochondrial division by increasing mitochondrial Sirt3

Cell Death and Disease
Mitochondrial transcription factor A (TFAM) plays a crucial role in mitochondrial fission beyond its canonical function in mtDNA maintenance. However, how TFAM regulates mitochondrial fission remains only partially understood. Fluorescence microscopy and

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Untangling the web: mitochondrial fission and apoptosis.

Developmental cell, 2004
Mitochondria exist as an interconnected network that is constantly remodeled by balancing membrane fission and fusion events. A new study by Szabadkai et al. in the October 8th issue of Molecular Cell shows that dynamin-related protein 1 (Drp1)-induced scission hinders the ability of mitochondria to transport calcium across the cell and mediate ...

Fish oil and omega3 in the prevention of metabolic disorders linked to obesity: role of mitochondrial function

, 2011
Obesity is one of the most serious public health problems of the 21st century. Along with the increase in obesity, there is a parallel increase in the prevalence of type 2 diabetes, impaired glucose tolerance, atherogenic dyslipidemia (high plasma ...

PDCD5 Contributes to Airway Epithelial Cell Damage via Mitochondrial Pathway and Participates in COPD Pathogenesis

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Airway epithelial injury plays a critical role in the pathogenesis of chronic obstructive pulmonary disease (COPD). Mitochondrial dysfunction is implicated in this injury, while the underlying mechanism remains incompletely understood. RNA sequencing was conducted to identify key genes involved in mitochondrial dysfunction in airway epithelial

Deficiency of Mitochondrial Fatty Acid Enzyme, CPT1A, Underlies Airway Epithelial Barrier Dysfunction in Severe Asthma

Allergy, EarlyView.
Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe

Machine learning‐driven investigation on liquid–liquid phase separation‐related prognostic signature in diffuse large B‐cell lymphoma

British Journal of Haematology, EarlyView.
Summary Diffuse large B‐cell lymphoma (DLBCL) is the most common aggressive non‐Hodgkin lymphoma and is characterized by substantial heterogeneity. This study aimed to develop a liquid–liquid phase separation (LLPS)‐related prognostic model to improve risk stratification.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.
