RNA dysregulation as a determinant of aging and neurodegenerative vulnerability.
Trends in cell biology · 2026
In the nervous system, aging causes deterioration of cellular and molecular processes that are associated with declines in cognition, sensory perception, and motor coordination. Aging is also the strongest risk factor for neurodegenerative disease, yet the mechanisms by which aging …

Imaging Cellular Metabolic Rewiring with SuMMIT-SRS.
bioRxiv : the preprint server for biology · 2025
Cells dynamically rewire their metabolic pathways in response to physiological and pathological cues. Such plasticity is particularly critical in neurons, stem cells, cancer cells, and immune cells, where biosynthetic demands can shift rapidly. However, current metabolic imaging techniques using isotope …

RNA triggers chronic stress during neuronal aging.
bioRxiv : the preprint server for biology · 2025
Neurodegenerative diseases are linked with dysregulation of the integrated stress response (ISR), which coordinates cellular homeostasis during and after stress events. Cellular stress can arise from several sources, but there is significant disagreement about which stress might contribute to aging …

Neuronal aging causes mislocalization of splicing proteins and unchecked cellular stress.
Nature neuroscience · 2025 · 28(6): 1174-1184
Aging is one of the most prominent risk factors for neurodegeneration, yet the molecular mechanisms underlying the deterioration of old neurons are mostly unknown. To efficiently study neurodegeneration in the context of aging, we transdifferentiated primary human fibroblasts from aged …

Zfp697 is an RNA-binding protein that regulates skeletal muscle inflammation and remodeling.
Proceedings of the National Academy of Sciences of the United States of America · 2024 · 121(34): e2319724121
Skeletal muscle atrophy is a morbidity and mortality risk factor that happens with disuse, chronic disease, and aging. The tissue remodeling that happens during recovery from atrophy or injury involves changes in different cell types such as muscle fibers, and …

Zfp697 is an RNA-binding protein that regulates skeletal muscle inflammation and regeneration.
bioRxiv : the preprint server for biology · 2023
Muscular atrophy is a mortality risk factor that happens with disuse, chronic disease, and aging. Recovery from atrophy requires changes in several cell types including muscle fibers, and satellite and immune cells. Here we show that Zfp697/ZNF697 is a damage-induced …

Aging RNA granule dynamics in neurodegeneration.
Frontiers in molecular biosciences · 2022 · 9: 991641
Disordered RNA-binding proteins and repetitive RNA sequences are the main genetic causes of several neurodegenerative diseases, including amyotrophic lateral sclerosis and Huntington's disease. Importantly, these components also seed the formation of cytoplasmic liquid-like granules, like stress granules and P bodies. …

Systematic review of dementia prevalence and incidence in United States race/ethnic populations.
Alzheimer's & dementia : the journal of the Alzheimer's Association · 2017 · 13(1): 72-83
To identify incidence and prevalence of dementia in racial and ethnic populations in the United States. A systematic review of literature. A total of 1215 studies were reviewed; 114 were included. Dementia prevalence rates reported for age 65+ years from …

ALS-linked TDP-43 mutations produce aberrant RNA splicing and adult-onset motor neuron disease without aggregation or loss of nuclear TDP-43.
Proceedings of the National Academy of Sciences of the United States of America · 2013 · 110(8): E736-45
Transactivating response region DNA binding protein (TDP-43) is the major protein component of ubiquitinated inclusions found in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) with ubiquitinated inclusions. Two ALS-causing mutants (TDP-43(Q331K) and TDP-43(M337V)), but not wild-type human TDP-43, …

Evidence for premature aging due to oxidative stress in iPSCs from Cockayne syndrome.
Human molecular genetics · 2012 · 21(17): 3825-34
Cockayne syndrome (CS) is a human premature aging disorder associated with neurological and developmental abnormalities, caused by mutations mainly in the CS group B gene (ERCC6). At the molecular level, CS is characterized by a deficiency in the transcription-couple DNA …

Hippocampus-dependent learning is associated with adult neurogenesis in MRL/MpJ mice.
Hippocampus · 2009 · 19(7): 658-69
The hippocampus is involved in declarative memory and produces new neurons throughout adulthood. Numerous experiments have been aimed at testing the possibility that adult neurogenesis is required for learning and memory. However, progress has been encumbered by the fact that …
