Mitochondria-originated redox signalling regulates KLF-1 to promote longevity in Caenorhabditis elegans

open access: yesRedox Biology, 2022
Alternations of redox metabolism have been associated with the extension of lifespan in roundworm Caenorhabditis elegans, caused by moderate mitochondrial dysfunction, although the underlying signalling cascades are largely unknown.

Novel ELAC2 Mutations in Individuals Presenting with Variably Severe Neurological Disease in the Presence or Absence of Cardiomyopathy

open access: yesLife, 2023
Transcription of mitochondrial DNA generates long polycistronic precursors whose nucleolytic cleavage yields the individual mtDNA-encoded transcripts. In most cases, this cleavage occurs at the 5′- and 3′-ends of tRNA sequences by the concerted action of

TOM40 Mediates Mitochondrial Dysfunction Induced by α-Synuclein Accumulation in Parkinson's Disease. [PDF]

open access: yes, 2013
Alpha-synuclein (α-Syn) accumulation/aggregation and mitochondrial dysfunction play prominent roles in the pathology of Parkinson's disease. We have previously shown that postmortem human dopaminergic neurons from PD brains accumulate high levels of ...

Application of Genome Sequencing from Blood to Diagnose Mitochondrial Diseases

open access: yes, 2021
Mitochondrial diseases can be caused by pathogenic variants in nuclear or mitochondrial DNA-encoded genes that often lead to multisystemic symptoms and can have any mode of inheritance. Using a single test, Genome Sequencing (GS) can effectively identify

Mitochondrial heterogeneity in diseases

open access: yesSignal Transduction and Targeted Therapy, 2023
AbstractAs key organelles involved in cellular metabolism, mitochondria frequently undergo adaptive changes in morphology, components and functions in response to various environmental stresses and cellular demands. Previous studies of mitochondria research have gradually evolved, from focusing on morphological change analysis to systematic multiomics,

Mitochondrial DNA deletions and neurodegeneration in multiple sclerosis

open access: yes, 2010
Cerebral atrophy is a correlate of clinical progression in multiple sclerosis (MS). Mitochondria are now established to play a part in the pathogenesis of MS.

Neuroimaging of mitochondrial disease [PDF]

open access: yesMitochondrion, 2008
Mitochondrial disease represents a heterogeneous group of genetic disorders that require a variety of diagnostic tests for proper determination. Neuroimaging may play a significant role in diagnosis. The various modalities of nuclear magnetic resonance imaging (MRI) allow for multiple independent detection procedures that can give important anatomical ...

Clinically translatable mitochondrial gene therapy in muscle using tandem mtZFN architecture

open access: yesEMBO Molecular Medicine
Mutations in the mitochondrial genome (mtDNA) often lead to clinical pathologies. Mitochondrially-targeted zinc finger nucleases (mtZFNs) have been successful in reducing the levels of mutation-bearing mtDNA both in vivo and in vitro, resulting in a ...

Deceleration of fusion–fission cycles improves mitochondrial quality control during aging

open access: yes, 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.

Maternal age effect and severe germ-line bottleneck in the inheritance of human mitochondrial DNA [PDF]

open access: yes, 2014
The manifestation of mitochondrial DNA (mtDNA) diseases depends on the frequency of heteroplasmy (the presence of several alleles in an individual), yet its transmission across generations cannot be readily predicted owing to a lack of data on the size ...
