Role of GTPase-Dependent Mitochondrial Dynamins in Heart Diseases

Frontiers in Cardiovascular Medicine, 2021
Heart function maintenance requires a large amount of energy, which is supplied by the mitochondria. In addition to providing energy to cardiomyocytes, mitochondria also play an important role in maintaining cell function and homeostasis.

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

Plant mitochondrial fission and fusion

Plant Biotechnology, 2005
Single plant cells have hundreds of mitochondria that move around and change their shape through the processes of fission and fusion. The Arabidopsis genome has genes for two dynamin-related proteins, DRP3A and DRP3B, that are similar to genes involved in mitochondrial fission in yeasts. DRP3A and DRP3B were localized to mitochondrial constricted sites

Deceleration of fusion-fission cycles improves mitochondrial quality control during aging. [PDF]

PLoS Computational Biology, 2012
Mitochondrial dynamics and mitophagy play a key role in ensuring mitochondrial quality control. Impairment thereof was proposed to be causative to neurodegenerative diseases, diabetes, and cancer.

Mitochondrial cristae remodelling is associated with disrupted OPA1 oligomerisation in the Huntington's disease R6/2 fragment model [PDF]

, 2017
There is evidence of an imbalance of mitochondrial fission and fusion in patients with Huntington's disease (HD) and HD animal models. Fission and fusion are important for mitochondrial homeostasis including mitochondrial DNA (mtDNA) maintenance and may ...

Altered brain energetics induces mitochondrial fission arrest in Alzheimer's Disease. [PDF]

, 2016
Altered brain metabolism is associated with progression of Alzheimer's Disease (AD). Mitochondria respond to bioenergetic changes by continuous fission and fusion.

Drosophila Parkin requires PINK1 for mitochondrial translocation and ubiquitinates Mitofusin [PDF]

, 2010
Loss of the E3 ubiquitin ligase Parkin causes early onset Parkinson's disease, a neurodegenerative disorder of unknown etiology. Parkin has been linked to multiple cellular processes including protein degradation, mitochondrial homeostasis, and autophagy;

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

Hepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

Hepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

Implications of mitochondrial dynamics on neurodegeneration and on hypothalamic dysfunction [PDF]

, 2015
Mitochondrial dynamics is a term that encompasses the movement of mitochondria along the cytoskeleton, regulation of their architecture, and connectivity mediated by tethering and fusion/fission.
