Chimeric antigen receptor (CAR)-T cell therapy has shown success in hematologic malignancies but remains limited in solid tumors due to poor persistence, migration, and tumor microenvironment-induced exhaustion. In an investigator-initiated trial in relapsed/refractory ovarian cancer, …
Pulmonary hypertension (PH) is a progressive disease in which the pulmonary arteries thicken and narrow, raising pulmonary vascular resistance (PVR) and eventually straining the right ventricle. Known gene mutations explain only a minority of cases …
Cellular senescence is an irreversible program of cell-cycle arrest that accumulates with age, contributing to chronic inflammation and various age-related diseases. A key feature of senescence paradigms is mitochondrial dysfunction, which involves not just a …
The increasing global burden of age-related diseases necessitates interventions that target the unified biological processes of aging, as outlined by the expanding framework of fourteen interconnected hallmarks. This review establishes nicotinamide adenine dinucleotide (NAD⁺) as …
Researchers found that cutting calorie intake by 50% in mice slowed age-related damage to the liver and kidneys, reducing fibrosis, metabolic stress, and cellular senescence markers. The protective effect appeared linked to activation of SIRT1, …
Researchers discovered that a single dose of radiation therapy used to treat dangerous heart rhythms causes lasting epigenetic changes—modifications that affect which genes are active without changing DNA sequence—leading to improved electrical conduction in heart …
Aging is accompanied by loss of motor function driven by mitochondrial oxidative stress. To examine how genotype and sex modulate this process, we exposed Oregon-R (wild-type) and vestigial (wing-deficient) Drosophila of both sexes to chronic …
Aging is commonly viewed as a consequence of cumulative molecular damage and declining stress resilience. However, this perspective overlooks the possibility that aging may primarily arise from an efficiency loss of integrated cellular operation. Here, …
Ginsenoside Rg1 (Rg1), an active compound in Panax ginseng C. A. Meyer (ginseng), has shown potential to ameliorate age-related cell damage and extend lifespan in multiple model organisms. However, the precise molecular mechanisms of its …
Researchers found that terbinafine (an antifungal) and miglustat (a diabetes drug) activate mitochondrial stress responses that extended lifespan and improved health markers in C. elegans worms and human cells. The discovery suggests these existing drugs …
Researchers found that corylin, a flavonoid from a traditional medicinal plant, extended lifespan and improved stress resistance in C. elegans worms by activating two key proteins that enhance cellular housekeeping and mitochondrial health. While promising, …
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 …
Researchers discovered that ATG-18, a protein known for triggering cellular cleanup, extends lifespan in worms through a completely different mechanism than expected. The protein interacts with a metabolic enzyme (PCK-2) to relay signals from the …
The influence of lifestyle factors, such as diet, on the effectiveness of T cell-mediated cancer immunotherapies remains unclear. Here, we demonstrate that the ketogenic diet (KD)-induced ketone metabolite β-hydroxybutyrate (BHB) augments chimeric antigen receptor (CAR) …
Acute-on-chronic liver failure (ACLF) is a severe liver syndrome marked by systemic inflammation and high mortality, often complicated by autophagy impairment and mitochondrial dysfunction. This study investigates atractylenolide I (AT-1), a compound from Atractylodes macrocephala, …
Researchers found that hydrolysates (broken-down proteins) from fava beans and peas both reduced aging signs in C. elegans worms, but through different cellular mechanisms—fava bean via antioxidant effects, pea via heat-stress resistance. This suggests legume …
Hydra is a freshwater cnidarian genus that provides a unique comparative model for aging research, contrasting the immortal H. vulgaris with the aging-inducible H. oligactis. Here, we report a high-quality, chromosome-level genome assembly of H. …
Researchers used lab-grown cells to show that mitochondrial DNA variants affecting energy production influence telomere length by controlling reactive oxygen species and NAD levels. This suggests that inherited mitochondrial traits may influence how quickly our …
Ovarian aging is characterized by progressive follicular reserve depletion, mitochondrial dysfunction, oxidative stress, and endocrine decline. This review examines the molecular mechanisms driving ovarian aging and evaluates emerging therapeutic strategies to preserve reproductive longevity. Key …
Heterozygous mutations in the Glucocerebrosidase gene (GBA1), encoding the lysosomal hydrolase Beta-glucocerebrosidase (GCase), are a genetic risk factor for Parkinsons disease (PD). To explore the pathophysiological consequences of these mutations, we have used fibroblasts and …
