Bacterial dynamin-like proteins reveal mechanism for membrane fusion

Nature Communications, 2018
The dynamin superfamily of large GTPases comprises specialized members that catalyze fusion and fission of biological membranes. While fission-specific proteins such as dynamin work as homo-oligomeric complexes, many fusion catalysts such as mitofusins ...

Parkin uses the UPS to ship off dysfunctional mitochondria [PDF]

, 2011
Parkin is a ubiquitin E3 ligase that is implicated in familial Parkinson disease (PD). Previous studies have established its role in mitophagy, a pathway whereby dysfunctional mitochondria are targeted for autophagic degradation.

Rapid degradation of mutant SLC25A46 by the ubiquitin-proteasome system results in MFN1/2-mediated hyperfusion of mitochondria. [PDF]

, 2017
SCL25A46 is a mitochondrial carrier protein that surprisingly localizes to the outer membrane and is distantly related to Ugo1. Here we show that a subset of SLC25A46 interacts with mitochondrial dynamics components and the MICOS complex.

Mitochondrial fusion: Reaching the end of mitofusin’s tether [PDF]

Journal of Cell Biology, 2016
In this issue, Qi et al. (2016. J. Cell Biol. https://doi.org/10.1083/jcb.201609019) provide structural insights into the mechanisms of mitochondrial outer membrane fusion by investigating the structure of mitofusin 1 (MFN1). This work proposes a new model to explain the important and elusive process of MFN-mediated mitochondrial fusion.

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Mitofusins regulate lipid metabolism to mediate the development of lung fibrosis

Nature Communications, 2019
Mitochondria of alveolar type 2 epithelial cells (AEC2) in the lung have been suggested to play a role in the development of idiopathic pulmonary fibrosis (IPF).

Mitochondrial fusion but not fission regulates larval growth and synaptic development through steroid hormone production

eLife, 2014
Mitochondrial fusion and fission affect the distribution and quality control of mitochondria. We show that Marf (Mitochondrial associated regulatory factor), is required for mitochondrial fusion and transport in long axons.

Role of Lipids and Divalent Cations in Membrane Fusion Mediated by the Heptad Repeat Domain 1 of Mitofusin

Biomolecules, 2023
Mitochondria are highly dynamic organelles that constantly undergo fusion and fission events to maintain their shape, distribution and cellular function.

Unveiling the role of mitofusin proteins in periodontal inflammation: Mitofusin-1 and Mitofusin-2 perspectives

Tanta Dental Journal
Abstract Periodontal diseases result from the complex interplay between microbial pathogens and the host immune response. Emerging evidence suggests that alterations in mitochondrial dynamics proteins, particularly Mitofusin-1 (MFN1) and Mitofusin-2 (MFN2), contribute to the pathogenesis of periodontal inflammation.

Biomaterial design strategies for enhancing mitochondrial transplantation therapy

BMEMat, EarlyView.
Biomaterials to facilitate mitochondrial transplantation therapy: biomaterials as barriers to protect mitochondria from pathophysiological microenvironments, like osmotic stress caused by the excessive concentration of calcium ion, reactive oxygen species, and advanced glycation end products; biomaterials integrating with biochemical cues to improve ...
