Low-fat vegan diet helps people lose weight without eating less

13 hours 55 minutes ago
A low-fat vegan diet may help people lose weight without counting calories, shrinking portions, or feeling constantly hungry. In a 16-week clinical trial, people eating mostly fruits, vegetables, grains, and legumes consumed about 357 fewer calories per day even though the total amount of food they ate barely changed.

Scientists uncover the hidden nerve network fueling breast cancer

14 hours 55 minutes ago
Researchers have uncovered a surprising way triple-negative breast cancer may turn the body against itself. Tumors appear to recruit macrophages—immune cells normally involved in healing and fighting infection—and use them to release a protein called BDNF that draws nerves into the tumor. Those nerves may then help the cancer grow, resist treatment, and potentially spread.

Age-dependent physiological responses and longevity in three Drosophila species with contrasting lifespans exposed to low temperature and constant darkness

17 hours 2 minutes ago
Aging is influenced by both genetic and environmental factors, yet comparative studies across species with different natural lifespans remain limited. We examined how reduced ambient temperature (18 °C vs 25 °C) and constant darkness, compared with a 12 h light/12 h dark cycle (DD vs LD), affect lifespan, age-related physiological traits, and gene expression in three Drosophila species with contrasting natural lifespans and climatic adaptations (tropical, short‑lived D. kikkawai, tropical,...

Caloric restriction suppresses colorectal tumors and melanoma through CD8 T cells in aged mice

17 hours 2 minutes ago
Caloric restriction (CR) has shown the potential to extend lifespan and reduce cancer risk; however, the mechanisms underlying CR-mediated tumor suppression are not fully understood. Here, we investigate age-dependent CR effects on tumor progression and anti-tumor immune responses in a murine CR model. In aged mice, CR, defined as a 30% reduction in caloric intake, significantly suppressed tumor growth in murine syngeneic models of colorectal cancer or melanoma. CR also enhanced tumor...

Mitochondrial Dysfunction as a Central Hub of Aging: From Molecular Cascades to Inter-Organ Communication Networks

17 hours 2 minutes ago
: Background: Mitochondrial dysfunction serves as a fundamental driver of the aging process, precipitating progressive functional decline through complex molecular cascades. Summary: This review elucidates the core mechanisms underpinning this dysfunction, including reactive oxygen species (ROS)-induced redox imbalance, mitochondrial DNA (mtDNA) damage accumulation, impaired mitophagy, and metabolic reprogramming. Crucially, we examine how mitochondria act as signaling hubs for inter-organ...

CXCR4-targeted dual softener for inducing senescence therapy in hepatic fibrosis

17 hours 2 minutes ago
Hepatic fibrosis is a central pathological driver of chronic liver diseases, including metabolic dysfunction-associated steatotic liver disease and alcohol-related liver disease, which collectively impose a growing global health burden. Fibrosis is primarily mediated by persistent activation of hepatic stellate cells (aHSCs) and excessive deposition of stiff extracellular matrix (ECM). The dense and rigid ECM-aHSCs network severely hinders drug delivery and penetration, posing a major challenge...

Mesenchymal Stromal Cell Rejuvenation Strategies to Enhance Clinical Translation in Cell Therapy

17 hours 2 minutes ago
Cell therapies represent a promising frontier in modern medicine. Mesenchymal stromal cells (MSCs) constitute a valuable source due to their minimal ethical concerns, low immunogenicity, negligible tumorigenicity in vivo, and robust paracrine activity mediated by the secretion of anti-inflammatory and angiogenic factors. Despite these advantages, MSCs undergo rapid replicative senescence accompanied by a progressive loss of stemness markers and functional potency. In this context, cellular...

TRF2 Recovers Ischemic Postconditioning Cardioprotection in Aged Myocardiocytes by Regulating CSNK2A2 Localization and FUNDC1 Dephosphorylation

17 hours 2 minutes ago
Ischemic postconditioning (I/Post), which is an effective intervention by activating endogenous cardioprotective pathways, recovers ischemia/reperfusion injury. However, this intervention is not as effective in older patients, and its mechanism needs to be further investigated. In this study, we found that myocardial telomeric repeat binding factor 2 (TRF2) protein expression in male aged mice (18 months of age) was lower than that in male adult mice (4 months of age). After ligation of the...

An ANGPTL8-AKT2-mTOR Axis Drives Adipose Senescence and Aging-Related Functional Decline

17 hours 2 minutes ago
Adipose tissue senescence is increasingly recognized as a key driver of systemic aging and age-related functional decline, yet the endocrine regulators that actively promote this process remain poorly defined. Angiopoietin-like protein 8 (ANGPTL8) is a metabolic factor implicated in lipid metabolism and inflammation and has been associated with multiple aging-related disorders. However, its direct role in adipose tissue senescence and organismal aging remains unclear. Here, we identify ANGPTL8...
