ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

The FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Expression of mitofusin 2R94Q in a transgenic mouse leads to Charcot-Marie-Tooth neuropathy type 2A [PDF]

, 2017
Charcot-Marie-Tooth disease type 2A is an autosomal dominant axonal form of peripheral neuropathy caused by mutations in the mitofusin 2 gene. Mitofusin 2 encodes a mitochondrial outer membrane protein that participates in mitochondrial fusion in ...

Regulation of Mitochondrial Dynamics and Neurodegenerative Diseases [PDF]

, 2011
Mitochondria are important cellular organelles in most metabolic processes and have a highly dynamic nature, undergoing frequent fission and fusion. The dynamic balance between fission and fusion plays critical roles in mitochondrial functions. In recent

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Mutational analysis of action of mitochondrial fusion factor mitofusin-2 [PDF]

Journal of Cell Science, 2005
Mitofusin-2 (Mfn2) is an essential component of mitochondrial fusion machinery, but its molecular mechanism of action is not clear. We found that a Mfn2 deletion mutant lacking two transmembrane spans (MfnΔTM) acts as a dominant-negative mutant and blocks mitochondrial fusion.

Optimal timing to assess exercise‐induced oxidative stress: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract There is a lack of consensus on optimal timing to assess redox biomarkers post‐exercise, limiting methodological standardisation and linking oxidative stress to physiology. We determined optimal post‐exercise oxidative stress assessment times using three redox biomarkers: glutathione, F2‐isoprostanes and protein carbonyls.

One day of environment‐induced heat stress causes injury to the murine kidney

Experimental Physiology, EarlyView.
Abstract Environment‐induced heat stress (EIHS) results from sustained body temperature elevation owing to prolonged exposure to heat and humidity. We hypothesized that EIHS would cause kidney injury and cellular dysfunction. To test this hypothesis, female C57 mice were exposed to EIHS (n = 14; 37.6°C, 42.0% relative humidity) or thermoneutral (TN ...

Burst mitofusin activation reverses neuromuscular dysfunction in murine CMT2A

eLife, 2020
Charcot–Marie-Tooth disease type 2A (CMT2A) is an untreatable childhood peripheral neuropathy caused by mutations of the mitochondrial fusion protein, mitofusin (MFN) 2.

Evidence for the involvement of lipid rafts localized at the ER-mitochondria associated membranes in autophagosome formation [PDF]

, 2016
Mitochondria-associated membranes (MAMs) are subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. This membrane scrambling between ER and mitochondria appears to play a critical role in the earliest steps of autophagy.
