Significats de mitochondrial fragmentation en anglès

Glutamate toxicity resulted in mitochondrial fragmentation and peri-nuclear accumulation of the organelles.

Overexpression of Tmem135 causes mitochondrial fragmentation and pathologies in the hearts of mice.

In this context, WNT4 knockdown led to decreased ATP production and increased mitochondrial fragmentation.

Inhibiting regulators of pathological mitochondrial fragmentation is proposed as an efficient strategy of neuroprotection.

Emerging evidence suggests that oxidative stress disturbs mitochondrial morphology dynamics, resulting in detrimental mitochondrial fragmentation.

Furthermore, we demonstrate for the first time neurite mitochondrial fragmentation and impaired mitochondrial dynamics in motor neurons expressing IMS mutant SOD1.

GDAP1 truncations that are found in patients who have CMT are not targeted to mitochondria and have lost mitochondrial fragmentation activity.

We show that PERK-regulated SIMH is a protective mechanism to prevent pathologic mitochondrial fragmentation and promote mitochondrial metabolism in response to ER stress.

Using a human iPSC model of diabetic endotheliopathy, we demonstrated that restoration of autophagy and prevention of mitochondrial fragmentation via calpain inhibition improves vascular integrity.

Importantly, calpain inhibition restored autophagy and reduced mitochondrial fragmentation, concurrent with maintenance of ATP production, normalized reactive oxygen species levels and reduced susceptibility to sIRI.

The loss of C. elegans fzo-1MFN results in mitochondrial fragmentation, decreased mitochondrial membrane potential and the induction of the mitochondrial unfolded protein response (UPRmt).

The Bid-mediated secondary boost of ROS formation downstream of LOX activity further involves mitochondrial fragmentation and release of mitochondrial apoptosis-inducing factor (AIF) to the nucleus.

We also identified activating phosphorylation of two fission proteins, pDRP1S616 and pMFFS146, in BTBR mice, consistent with the increased mitochondrial fragmentation that we observed.

Light-mediated activation (660 nm) of the Mito-FAP-MG-2I complex led to a rapid loss of mitochondrial respiration, decreased electron transport chain complex activity, and mitochondrial fragmentation.
