Advances in drug therapy for mitochondrial diseases.

open access: yesAnnals of Translational Medicine, 2020
Mitochondrial diseases are a group of clinically and genetically heterogeneous disorders driven by oxidative phosphorylation dysfunction of the mitochondrial respiratory chain which due to pathogenic mutations of mitochondrial DNA (mtDNA) or nuclear DNA (

Changes in neuronal CycD/Cdk4 activity affect aging, neurodegeneration, and oxidative stress. [PDF]

open access: yes, 2015
Mitochondrial dysfunction has been implicated in human diseases, including cancer, and proposed to accelerate aging. The Drosophila Cyclin-dependent protein kinase complex cyclin D/cyclin-dependent kinase 4 (CycD/Cdk4) promotes cellular growth by ...

Inhibition of the mitochondrial pyruvate carrier protects from excitotoxic neuronal death. [PDF]

open access: yes, 2017
Glutamate is the dominant excitatory neurotransmitter in the brain, but under conditions of metabolic stress it can accumulate to excitotoxic levels.

High throughput single cell analysis of mitochondrial heteroplasmy in mitochondrial diseases

open access: yesScientific Reports, 2020
Mitochondrial heteroplasmy, which fundamentally means intracellular heterogeneity of mitochondrial DNA (mtDNA), has been measured in a group of cells, regardless of intercellular heterogeneity.

Constitutive activation of the PI3K-Akt-mTORC1 pathway sustains the m.3243 A > G mtDNA mutation

open access: yesNature Communications, 2021
Heteroplasmic mtDNA mutations cause disease in humans. Here, Chung et al find the PI3K-Akt-mTORC1 pathway constitutively activated in cells with the heteroplasmic m.3243 A > G mutation, and inhibition of the pathway cell autonomously reduces mutant mtDNA

Mitochondrial disease in flies

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2004
The Drosophila mutant technical knockout (tko), affecting the mitochondrial protein synthetic apparatus, exhibits respiratory chain deficiency and a phenotype resembling various features of mitochondrial disease in humans (paralytic seizures, deafness, developmental retardation).

Effects of oxidative stress on hepatic encephalopathy pathogenesis in mice

open access: yesNature Communications, 2023
Oxidative stress plays a crucial role in the pathogenesis of hepatic encephalopathy (HE), but the mechanism remains unclear. GABAergic neurons in substantia nigra pars reticulata (SNr) contribute to the motor deficit of HE.

Neuropathology of mitochondrial diseases

open access: yesBioscience Reports, 2007
The term “mitochondrial diseases” (MD) refers to a group of disorders related to respiratory chain dysfunction. Clinical features are usually extremely heterogeneous because MD may involve several tissues with different degrees of severity. Muscle and brain are mostly affected, probably because of their high dependence on oxidative metabolism.

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability [PDF]

open access: yes, 2018
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent R loops may become pathological

Mitochondrial diseases

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 2004
By convention, the term "mitochondrial diseases" refers to disorders of the mitochondrial respiratory chain, which is the only metabolic pathway in the cell that is under the dual control of the mitochondrial genome (mtDNA) and the nuclear genome (nDNA).
