Massively parallel genetic perturbation suggests the energetic structure of an amyloid-β transition state

7 months 3 weeks ago
Amyloid aggregates are pathological hallmarks of many human diseases, but how soluble proteins nucleate to form amyloids is poorly understood. Here, we use combinatorial mutagenesis, a kinetic selection assay, and machine learning to massively perturb the energetics of the nucleation reaction of amyloid-β (Aβ42), the protein that aggregates in Alzheimer's disease. In total, we measure the nucleation rates of >140,000 variants of Aβ42 to accurately quantify the changes in free energy of...

Trends and mechanisms of Alzheimer's disease and hearing impairment: A 20-year perspective

7 months 3 weeks ago
Alzheimer's disease (AD) and hearing loss (HL) are major age-related public health challenges with emerging evidence suggesting their interconnection. This study aimed to investigate global research trends, shared molecular mechanisms, and clinical implications of AD and HL. A total of 349 articles published between 2004 and 2024 were retrieved from the Web of Science Core Collection and analyzed using VOSviewer and CiteSpace. GeneCards and STRING databases were used to explore molecular targets...

Sequential transcriptional programs underpin activation of hippocampal stem cells

7 months 3 weeks ago
Adult neural stem cells exist on a continuum from deep to shallow quiescence that changes in response to injury or aging; however, the transcription factors controlling these stepwise transitions have not been identified. Single-cell transcriptomic analyses of mice with loss of function or increased levels of the essential activation factor Ascl1 reveal that Ascl1 promotes the activation of hippocampal neural stem cells by driving these cells out of deep quiescence, despite its low protein...

Biological age acceleration in Alzheimer's disease modulates relative cortical to medial temporal lobe neurodegeneration

7 months 3 weeks ago
Alzheimer's disease (AD) is highly associated with aging, typically presenting with amnestic, multi-domain cognitive impairment and greater medial temporal lobe (MTL) atrophy relative to cortex. However, approximately 15 % of AD cases present atypically, often at younger ages and with greater cortical involvement relative to MTL. This association between age and AD presentation is imperfect: some younger-onset cases are typical, amnestic presentations while some older-onset cases present less...

Using RNA therapeutics to promote healthy aging

7 months 3 weeks ago
Aging is characterized by a gradual decline of cellular and physiological functions over time and an increased risk of different diseases. RNA therapeutics constitute an emerging approach to target the molecular mechanisms of aging and age-related diseases via rational design and have several advantages over traditional drug therapies, including high specificity, low toxicity and the potential for rapid development and production. Here, we discuss the latest developments in RNA therapeutics...
