Proteomics, metabolomics, transcriptomics, and multi-omics aging studies
Aging is accompanied by progressive physiological decline and an increased risk of chronic disease, motivating the search for interventions that promote healthy longevity. We found that mid-life administration of Corylin, a flavonoid derived from Psoralea …
Aortic dissection (AD) is a catastrophic cardiovascular syndrome with an in-hospital mortality of more than 90%. We previously identified oxidative inactivation of sarcoplasmic/endoplasmic reticulum Ca2+-ATPase 2 (SERCA2) at cysteine 674 (C674) as a driver of …
The bone marrow niche (BMN) plays a central role in regulating hematopoietic stem-cell (HSC) maintenance, lineage commitment, and immune homeostasis, while also supporting osteogenesis and maintaining skeletal integrity. Once considered static, the BMN is now …
This review examines how immunosenescence (age-related immune decline) drives lung diseases like COPD, fibrosis, and cancer, and surveys emerging treatments including senolytics, stem cell therapy, and lifestyle interventions. While it synthesizes current knowledge well, it's …
Iron overload induces cellular stress and is implicated in diverse pathological conditions. Nevertheless, the epigenetic mechanisms governing mammalian cellular responses to iron overload remain poorly characterized. Using multi-omics profiling in human granulosa cells, we show …
Researchers reviewed how people who live to 100+ maintain surprisingly youthful immune function despite extreme age, resisting the chronic inflammation and immune decline that typically accompany aging. They identified several biological mechanisms—including controlled inflammatory pathways, …
Histone deacetylases (HDACs) regulate transcription and catalyze deacetylation predominantly within canonical transcriptional complexes. Nevertheless, the mechanistic role of other HDAC-associated proteins in orchestrating this process remains incompletely understood. To systematically decode endogenous HDAC interactomes in …
Researchers analyzed sleep duration against 23 biological aging markers across multiple organ systems and found a U-shaped pattern: both too little (<6 hours) and too much (>8 hours) sleep are linked to faster biological aging, …
A major clinical trial tracked 864 different metabolites in people doing long-term caloric restriction and found distinct shifts in carbohydrate and fat metabolism—with early changes during weight loss giving way to compensatory responses during weight …
ABSTRACT: Gestational diabetes mellitus (GDM) is a rapidly increasing global health challenge that is closely linked to the rising rates of obesity and type 2 diabetes mellitus. Similarly, metabolic dysfunction-associated steatotic liver disease (MASLD) has …
Researchers found that boosting adrenaline-like signaling in the gut of female fruit flies extends their lifespan by activating a specific protein called CrebB. This suggests that neuroendocrine pathways—which are conserved across animals—might be a viable …
Researchers developed a standardized method to adapt epigenetic aging clocks—which measure biological age through DNA methylation patterns—from older microarray technology to newer sequencing platforms using cell-free DNA. This is important because sequencing is becoming the …
Researchers found abnormal mitochondrial function in patients with geographic atrophy (a blinding eye disease) by analyzing fluid from inside the eye. In a small early-stage trial, oral alpha-ketoglutarate supplementation successfully increased the compound's levels in …
Organisms need to be able to adapt to a changing environment in order to survive. The adaptive response invoked by a low dose of a stressor resulting in resistance to high levels of that stressor …
Researchers found that losartan, a common blood pressure medication, shifted the metabolic fingerprint of aged mice and pre-frail older men toward a younger state. The effect appeared dose-dependent in humans and required functional angiotensin II …
The human striatum is a central hub for diverse motor, cognitive, and affective behaviors, yet it lacks obvious cytoarchitectural boundaries defining functional territories. Here, we uncover a robust and molecularly defined mesoscale architecture in the …
The increasing demand for natural food preservatives has intensified research into indigenous microorganisms with biopreservative properties. This study investigated the antimicrobial efficacy and biopreservative potential of lactic acid bacteria (LAB) isolated from traditionally fermented Dacryodes …
T cell exhaustion (TCE), a hallmark of chronic infections and cancer, is characterized by progressive loss of effector function, sustained expression of inhibitory receptors, and stable transcriptional/epigenetic reprogramming. Within the tumor microenvironment (TME), exhausted CD8+ …
Modern humans now routinely survive to advanced ages, in far greater proportions than ancestral populations, and thus experience the consequences of molecular pathways optimized for youth yet still active in old age. Natural selection weakens …
Gut microbiota resilience, the capacity of intestinal microbial communities to resist, adapt, and recover from perturbations has emerged as a critical determinant of human health and longevity. Environmental stressors such as antibiotics, pollutants, poor diet, …
