Senolytics dasatinib and quercetin in metabolic dysfunction-associated steatohepatitis: a proof-of-principle randomized, controlled trial

1 month 1 week ago
Cellular senescence plays an important role in hepatic inflammation and fibrosis^(1-3). However, whether senescence represents a potential therapeutic target in humans with metabolic dysfunction-associated steatohepatitis (MASH) remains unexplored. Here we report the results of a phase-2, double-blind, randomized, placebo-controlled trial of intermittent senolytic therapy with dasatinib plus quercetin (D + Q) in participants with fibrotic MASH. Thirty-one participants (median age 56 years; 76%...

Development of A10P3C, an isoform-selective inhibitor of EGLN2, for targeting breast cancer

1 month 1 week ago
Oxygen sensing signaling is mainly mediated by EGLN prolyl hydroxylases, which plays important roles in physiology and diseases. Among them, EGLN2 plays an oncogenic role in breast cancer. However, the development of isoform-selective EGLN2 inhibitors remains a major challenge. Here, we report the identification of A10P3C, a small-molecule inhibitor that exhibits high potency and exceptional selectivity toward EGLN2. Guided by conformational sampling, ensemble-docking-based...

Hypertension fuels osteoarthritis through neuroendocrine signaling

1 month 1 week ago
Osteoarthritis (OA) is a degenerative joint disease, the progression of which is accelerated by systemic metabolic stress. Here, we identified a neuroendocrine pathway through which hypertension accelerates OA pathogenesis in joints predisposed by mechanical injury or aging. Nationwide cohort analyses and hypertensive mouse models demonstrated that elevated blood pressure exacerbates OA pathogenesis. OA-primed chondrocytes up-regulated arginine vasopressin (AVP) receptor 1A (AVPR1A), rendering...

X and Y chromosomes as determinants of aging and disease

1 month 1 week ago
Sex differences have traditionally been attributed to gonadal hormones, but accumulating evidence shows that sex chromosomes exert distinct, cell-autonomous effects on health, aging, and disease. XX and XY complements alter gene dosage, epigenetic programming, immune signaling, metabolism, and cellular stress responses, which shape aging and disease trajectories in women and men. This Review integrates mechanistic advances in sex chromosome biology-including escape from X chromosome...

Reframing menopause and menopause hormone therapy as opportunities for healthy aging

1 month 1 week ago
Menopause is an important biological transition with up to 72 symptoms that shapes aging trajectories across organs and encompasses ~40% of the female lifespan. Although menopause awareness is increasing, research on strategies for menopause symptom management and optimizing health in the postmenopausal period is lacking. This Review highlights that menopause characteristics, such as type, timing, and symptom burden, influence health outcomes and later-life disease risk. Similarly, menopause...

Glucose-deprived tumor microenvironment activates AMP-activated protein kinase to drive adoptively transferred T helper 9 cell senescence

1 month 1 week ago
T helper 9 (Th9) cells show promise for adoptive cell therapy (ACT) against solid tumors. However, clinical application faces challenges regarding their persistence in the tumor microenvironment (TME). We observed that tumor growth gradually reduced glucose concentrations in the TME, accompanied by a decline in transferred Th9 cells and their effector functions, due to Th9 cell senescence. Restoring glucose concentrations suppressed Th9 cell senescence, thereby improving their persistence....

Centenarians and oldest olds in Liguria - COOL: A multidisciplinary cohort study to investigate the genetic determinants of cognitive well-being in Genoa, Italy. Rationale, study protocol and baseline cohort profile

1 month 1 week ago
CONCLUSIONS: We showed that the protocol is feasible and agreeable to participants and their families. A comprehensive phenotype dataset was established, and DNA samples were stored for subsequent genomic analysis. Centenarians exhibited a broad spectrum of cognitive profiles, from preserved cognition to severe dementia. Some data were unavailable, which should be considered in light of the study design and the characteristics of the cohort. These findings will eventually allow investigation of...

Peripheral-central interactions shape the decoupling between auditory brainstem response amplitudes and auditory thresholds during aging and noise exposure: a computational modeling study

1 month 1 week ago
Age-related and noise-induced hearing loss reflect progressive cochlear degeneration and adaptive changes in central auditory pathways, yet their joint effects on auditory brainstem response (ABR) amplitudes and auditory thresholds remain unclear. We developed the Auditory Homeostatic Dynamics Model (AHDM), a three-state ordinary differential equation model of hair-cell sensory function, cochlear synaptic integrity, and activity-dependent central compensation across low-, mid-, and...

Ferroptosis-driven inflammaging in age-associated degenerative disorders: Molecular mechanisms and therapeutic potential of natural products

1 month 1 week ago
Persistent low-grade inflammation, oxidative stress, cellular senescence, and disturbance of cellular homeostasis are all connected with ageing and can lead to the development of age-related diseases. Ferroptosis, an iron-dependent type of controlled cell death, has been linked to these processes more and more. It may represent a key connection between inflammation, oxidative damage, and tissue failure as people age. With a focus on neurodegenerative, cardiovascular, metabolic, pulmonary, and...
