Mfn2 Overexpression Attenuates MPTP Neurotoxicity In Vivo [PDF]
International Journal of Molecular Sciences, 2021 Mitochondrial dysfunction represents a critical event in the pathogenesis of Parkinson’s disease (PD). Increasing evidence demonstrates that disturbed mitochondrial dynamics and quality control play an important role in mitochondrial dysfunction in PD. Our previous study demonstrated that MPP+ induces mitochondrial fragmentation in vitro. In this study,

MFN2 mutations cause compensatory mitochondrial DNA proliferation [PDF]
Brain, 2012 ARTICLE Sir, We read with great interest the report of a Tunisian family by Rouzier et al . (2011) describing the neurological disorder linked to a novel heterozygous missense mutation in MFN2 (1p36.2) (Rouzier et al ., 2011). MFN2 mutations typically cause autosomal dominant axonal Charcot–Marie–Tooth disease (CMT2A, OMIM 609260), with peripheral ...

Mitofusin-2 modulates the epithelial to mesenchymal transition in thyroid cancer progression
Scientific Reports, 2021 Here, we investigated the potential roles of Mitofusin-2 (MFN2) in thyroid cancer progression. MFN2 regulates mitochondrial fusion/division in cells and plays an important role in various aspects of cell metabolism.

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 ...

Two rare human mitofusin 2 mutations alter mitochondrial dynamics and induce retinal and cardiac pathology in Drosophila. [PDF]
PLoS ONE, 2012 Mitochondrial fusion is essential to organelle homeostasis and organ health. Inexplicably, loss of function mutations of mitofusin 2 (Mfn2) specifically affect neurological tissue, causing Charcot Marie Tooth syndrome (CMT) and atypical optic atrophy. As

Hepatology, EarlyView., 2022 Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease
Hepatology, EarlyView., 2022 RIPK3 dampens mitochondrial bioenergetics and lipid droplet dynamics in metabolic liver disease. Abstract Background and Aims Receptor‐interacting protein kinase 3 (RIPK3) mediates NAFLD progression, but its metabolic function is unclear. Here, we aimed to investigate the role of RIPK3 in modulating mitochondria function, coupled with lipid droplet (LD)

Complementation between mouse Mfn1 and Mfn2 protects mitochondrial fusion defects caused by CMT2A disease mutations [PDF]
, 2007 Mfn2, an oligomeric mitochondrial protein important for mitochondrial fusion, is mutated in Charcot-Marie-Tooth disease (CMT) type 2A, a peripheral neuropathy characterized by axonal degeneration.

MFN2Influences Amyotrophic Lateral Sclerosis Pathology [PDF]
, 2021 AbstractObjectiveTo better understand the pathology of amyotrophic lateral sclerosis, we used sequence data from patients seen at the University of Utah to identify novel disease-associated loci. We utilized bothin vitroandin vivostudies to determine the biological effect of patient mutations inMFN2.MethodSequence data for a total of 140 patients were ...
