Mitochondrial Fragmentation Due to Inhibition of Fusion Increases Cyclin B through Mitochondrial Superoxide Radicals. [PDF]

open access: yesPLoS ONE, 2015
During the cell cycle, mitochondria undergo regulated changes in morphology. Two particularly interesting events are first, mitochondrial hyperfusion during the G(1)-S transition and second, fragmentation during entry into mitosis.

Calcium Signalling: Mitofusins Promote Interorganellar Crosstalk [PDF]

open access: yesCurrent Biology, 2009
Juxtaposition of the endoplasmic reticulum with mitochondria facilitates Ca(2+) fluxes between the organelles. However, the molecular basis of interorganellar tethering remains unknown. A recent report has identified a fundamental role for the dynamin-related mitofusins in the tethering mechanism, thereby ensuring rapid and high fidelity Ca(2 ...

A mitofusin-dependent docking ring complex triggers mitochondrial fusion in vitro

open access: yeseLife, 2016
Fusion of mitochondrial outer membranes is crucial for proper organelle function and involves large GTPases called mitofusins. The discrete steps that allow mitochondria to attach to one another and merge their outer membranes are unknown.

Mitofusin 2 Dysfunction and Disease in Mice and Men

open access: yesFrontiers in Physiology, 2020
A causal relationship between Mitofusin (MFN) 2 gene mutations and the hereditary axonal neuropathy Charcot-Marie-Tooth disease type 2A (CMT2A) was described over 15 years ago. During the intervening period much has been learned about MFN2 functioning in

Ubiquitination and receptor-mediated mitophagy converge to eliminate oxidation-damaged mitochondria during hypoxia

open access: yesRedox Biology, 2021
The contribution of the Ubiquitin-Proteasome System (UPS) to mitophagy has been largely attributed to the E3 ubiquitin ligase Parkin. Here we show that in response to the oxidative stress associated with hypoxia or the hypoxia mimic CoCl2, the damaged ...

OPA1 and cardiolipin team up for mitochondrial fusion [PDF]

open access: yes, 2017
Fusion between the inner membranes of two mitochondria requires the GTPase optic atrophy 1 (OPA1), but the molecular mechanism is poorly understood. A study now shows that fusion of two liposomes can be performed by OPA1 tethered to just one liposome ...

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

open access: yesAnnals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Mitofusin1 in oocyte is essential for female fertility

open access: yesRedox Biology, 2019
Mitofusins (Mfn) are the important regulators of mitochondrial organization in mammalian cells; however, their roles during oocyte development remain unknown.

Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

open access: yesAnimal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.
