Targeting Mitochondria in Aging‐Related Diseases: Therapeutic Potential and Obstacles

MedComm, Volume 7, Issue 6, June 2026.
This article systematically summarized the specific mechanism of aging‐related diseases caused by mitochondrial dysfunction, and summarized the broad‐spectrum treatment methods and disease targeted treatment strategies for mitochondria. At the same time, it also pointed out the dilemma faced by mitochondrial targeted treatment.

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, Volume 41, Issue 6, Page 1516-1527, June 2026.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.

Mutant huntingtin impairs PNKP and ATXN3, disrupting DNA repair and transcription

eLife, 2019
How huntingtin (HTT) triggers neurotoxicity in Huntington’s disease (HD) remains unclear. We report that HTT forms a transcription-coupled DNA repair (TCR) complex with RNA polymerase II subunit A (POLR2A), ataxin-3, the DNA repair enzyme polynucleotide ...

Polyglutamine Disease: Acetyltransferases Awry [PDF]

Current Biology, 2002
Recent evidence indicates that inhibition of histone acetyltransferases may be a primary cause of cellular pathogenesis in polyglutamine diseases such as Huntington disease; the results raise the possibility that pharmacologic manipulation of protein acetylation levels could be of therapeutic benefit.

An Optimal Ubiquitin-Proteasome Pathway in the Nervous System: The Role of Deubiquitinating Enzymes

Frontiers in Molecular Neuroscience, 2014
The Ubiquitin-Proteasome Pathway (UPP), which is critical for normal function in the nervous system and is implicated in various neurological diseases, requires the small modifier protein ubiquitin to accomplish its duty of selectively degrading short ...

Noncanonical usage of stop codons in ciliates expands proteins with structurally flexible Q-rich motifs

eLife
Serine(S)/threonine(T)-glutamine(Q) cluster domains (SCDs), polyglutamine (polyQ) tracts and polyglutamine/asparagine (polyQ/N) tracts are Q-rich motifs found in many proteins.

Biophysical insights into how surfaces, including lipid membranes, modulate protein aggregation related to neurodegeneration

Frontiers in Neurology, 2013
There are a vast number of neurodegenerative diseases, including Alzheimer’s disease (AD), Parkinson’s disease (PD), and Huntington’s disease (HD), associated with the rearrangement of specific proteins to non-native conformations that promotes ...

Chemical Chaperones Reduce Aggregate Formation and Cell Death Caused by the Truncated Machado–Joseph Disease Gene Product with an Expanded Polyglutamine Stretch

Neurobiology of Disease, 2002
Machado–Joseph disease/spinocerebellar ataxia-3 (MJD/SCA-3) is an inherited neurodegenerative disorder caused by expansion of the polyglutamine stretch in the MJD gene-encoded protein ataxin-3.

The Huntington disease protein accelerates breast tumour development and metastasis through ErbB2/HER2 signalling

EMBO Molecular Medicine, 2013
In Huntington disease (HD), polyglutamine expansion in the huntingtin protein causes specific neuronal death. The consequences of the presence of mutant huntingtin in other tissues are less well understood.

Enhanced Age-Dependent Motor Impairment in Males of Drosophila melanogaster Modeling Spinocerebellar Ataxia Type 1 Is Linked to Dysregulation of a Matrix Metalloproteinase

Biology
Over the past two decades, Drosophila melanogaster has proven to be successful in modeling the polyglutamine (polyQ) (caused by CAG repeats) family of neurodegenerative disorders, including the faithful recapitulation of pathological features such as ...
