Vitamin K2 Extends Lifespan by Alleviating Mitochondrial Stress via the JNK-1/SIR-2.1/DAF-16 Signaling Axis in Caenorhabditis elegans

14 hours ago
Vitamin K2 is a fat-soluble vitamin that has been reported to exhibit significant anti-stress activity. Anti-stress properties are considered to be closely associated with lifespan extension. Therefore, we investigated the effects of vitamin K2 on the lifespan and stress resistance of Caenorhabditis elegans, as well as the underlying mechanisms. In the present study, we found that the effects of Vitamin K2 on C. elegans are concentration-dependent. High concentrations (10 μM) of Vitamin K2 are...

Cancer cachexia induces senescent reprogramming of brown adipose tissue and pro-cachectic S100A9 secretion by adipocytes

1 day 14 hours ago
Cancer-associated cachexia (CAC) is a multifactorial wasting syndrome characterized by progressive loss of fat and lean mass, systemic inflammation, and poor therapeutic responsiveness. While brown adipose tissue (BAT) is traditionally considered a protective, energy-dissipating organ, its qualitative remodeling in CAC remains poorly characterized.Here, we demonstrate that CAC induces a senescent conversion of BAT, marked by thermogenic failure, fibrosis, inflammation, and acquisition of a...

Building an ontology of resilience: Insights from the physical resilience literature

2 days 14 hours ago
Physical resilience is a term used to describe an individual's response to physical and physiological stressors across the fields of gerontology and rehabilitation sciences. However, the term has not yet undergone a rigorous examination of its underlying assumptions, which has hindered its theoretical development and empirical measurement. This paper reviews the existing definitions of physical resilience in the context of human physical and psychological systems to examine its underlying,...

The glymphatic system and meningeal lymphatic vessels: from physiology to pathophysiology, with insights into visualization

2 days 14 hours ago
The lymphatic system plays critical roles in immune defense, fluid homeostasis, substance metabolism, and cellular communication. Traditionally, it was believed that the vertebrate brain lacked a classical lymphatic system. Studies have revealed the presence of the glymphatic system (GS) and meningeal lymphatic vessels (MLVs), which are thought to play important roles in regulating material transport and immune processes within the central nervous system (CNS), in ways that resemble aspects of...

Activating p53<sup>Y220C</sup> with a mutant-specific small molecule

2 days 14 hours ago
TP53 is the most commonly mutated gene in cancer, but it remains recalcitrant to clinically meaningful therapeutic reactivation. We present here the discovery and characterization of a small molecule chemical inducer of proximity that activates mutant p53. We named this compound TRanscriptional Activator of p53 (TRAP-1) due to its ability to engage p53^(Y220C) and BRD4 in a ternary complex, which potently activates mutant p53 and triggers robust p53 target gene transcription. Treatment of...

SIRT1 Downregulation by Advanced Glycation End Products Activates RANKL-Dependent Osteoclast Signaling and Drives Chondrocyte Senescence During Osteoarthritis Development

2 days 14 hours ago
Advanced glycation end products (AGEs) accumulate with aging and metabolic stress and are increasingly implicated in osteoarthritis (OA) pathology. However, how AGEs regulate osteoclast-chondrocyte signaling remains poorly defined. Here, we integrated proteomic and transcriptomic analyses with machine learning to identify molecular networks altered by AGEs in osteoclasts. SIRT1 emerged as a central regulator suppressed following AGE exposure. Loss of SIRT1 deacetylase activity activated the...

Stress-induced CXCL13 regulates pancreatic exocrine homeostasis, age-related chronic inflammation, and cancer progression

2 days 14 hours ago
Pancreatic cancers, whose incidence increases with age, are often refractory to treatment. Here, we identified a core mechanism shared by physiological homeostasis, senescent cell accumulation during aging, and pancreatic cancers. Pancreatic acinar cells, when stressed, secrete CXCL13, which protects stressed cells while transiently activating paracrine Hippo/YAP signaling to induce proliferation and PD-L1-mediated immune protection to maintain organ homeostasis. In the aged pancreas,...

Low genetic risk for coronary artery disease underlies multigenerational longevity and healthy aging

2 days 14 hours ago
Aging is a major risk factor for chronic diseases. Unlike the general population, members of long-lived families maintain exceptional health as they age, with over 10 years delayed onset of their first chronic disease. We therefore hypothesize that one of the key features explaining healthy survival up to high ages (longevity) is the absence of chronic disease risk alleles. We investigated this hypothesis in the Leiden Longevity Study, a cohort with data from more than 420 long-lived families in...

ZNRF2-mediated CD-M6PR degradation and lysosomal dysfunction aggravate cellular senescence and aging

2 days 14 hours ago
Lysosomal dysfunction is a hallmark of cellular senescence, yet the mechanisms governing lysosomal protein trafficking remain incompletely understood. Here, we show that CD-M6PR, a principal receptor for lysosomal enzyme transport, is markedly reduced in senescent fibroblasts and in aged mice and humans, and that its loss correlates with the severity of autolysosomal impairment. Mechanistically, the reduction of CD-M6PR in senescent cells mainly stems from the accelerated proteasome-mediated...
