Somatic cancer variants enriched in Alzheimer's disease microglia-like cells drive inflammatory and proliferative states

1 month 3 weeks ago
Alzheimer's disease (AD) is a neurodegenerative condition characterized by microglia-mediated neuroinflammation. Deep (>1,000×) panel sequencing of 311 brain samples revealed enrichment of somatic single-nucleotide variants (sSNVs) in cancer driver genes in AD brains, especially in genes associated with clonal hematopoiesis (CH). These sSNVs were associated with clonal expansion and carried by both microglia-like brain macrophages (MLBMs) in multiple brain regions as well as paired blood,...

A skeletal muscle atlas shows neuromuscular junction adaptations to growth and atrophy

1 month 3 weeks ago
The molecular basis underlying muscle atrophy, as it occurs during disuse or aging, and activity-induced hypertrophy remain poorly understood. A major challenge has been defining the diverse cellular and niche environments within skeletal muscle, which is mostly composed of multinucleated myofibers. Here, we present a single-nucleus and single-cell transcriptomic atlas, coupled with spatial profiling, of mouse limb skeletal muscle under resting conditions and during experimentally induced...

A generative AI framework unifies human multi-omics to model aging, metabolic health, and intervention response

1 month 3 weeks ago
Understanding aging and complex diseases requires diverse data, ranging from molecular profiles to imaging and routine clinical tests. However, most multi-omic datasets measure only a subset of modalities and are confounded by batch effects. Here, we present AURORA (AI unification and reconstruction of omics reassembly atlas), a generative deep-learning platform that integrates seven modalities (including transcriptomics, metabolomics, microbiome, 3D and thermal facial imaging, and clinical...

A multi-tiered workflow for examining organic acid profiles delineates tissue-specific changes in fatty acyl partitioning during aging

1 month 3 weeks ago
Fatty acids (FAs), as the predominant organic acids, form a major component of the metabolome. We present a multi-tiered method that comprehensively captures FA diversity-including chain lengths (C2-C34), unsaturation, isomers, and endogenous forms-within a single biological specimen. This workflow quantifies the broadest range of free FAs reported to date. Integrated with two complementary tiers profiling the total FA pool from alkaline hydrolysis and esterified acyl compositions across lipid...

Ordinal GWAS analysis of the frailty phenotype identified a novel locus at 12q22 that underscores the role of the neurological and immune systems

1 month 3 weeks ago
Frailty is a complex trait that significantly increases the risk for negative health consequences, including hospitalization and disability. However, the evidence regarding the genetic basis of frailty phenotype (FP) is very limited. We conducted a genome-wide association study (GWAS) on FP using the data from the Canadian Longitudinal Study on Aging (CLSA). We classified the participants as non-frail, pre-frail, and frail, and performed a GWAS utilizing the ordinal logistic regression adjusted...
