Charting the expression landscape of human long non-coding RNAs across diverse biological contexts with LncExpDB 2.0
LncExpDB is a comprehensive expression database of human long non-coding RNAs (lncRNAs) across diverse biological contexts. Here, we present LncExpDB 2.0 (https://ngdc.cncb.ac.cn/lncexpdb/) with significant updates and enhancements as detailed below: (i) expansion of biological contexts from 9 to 15 by integrating immunotherapy, aging, metabolic diseases, neurodegenerative diseases, reproduction, and wound healing; (ii) identification of 44 752 highly expressed genes, 39 253 featured genes with...
scGeneBank: cross-species screening of functional gene sets at single-cell resolution
Single-cell transcriptomics is reshaping the study of cellular physiology and pathology by revealing fine-grained cell functions and states. Interpreting these signals across cell types, organs, and species benefits from curated gene sets and tools for comparative analysis. Here, we introduce scGeneBank (http://8.142.154.29/scGeneBank or http://www.genebank.info), a database and analysis portal for gene set-driven exploration at single-cell resolution. The resource integrates 1134 carefully...
Multi-target synergistic anti-aging: QG extends Caenorhabditis elegans lifespan through DAF-16/FOXO pathways, mitochondrial homeostasis and metabolic reprogramming
Aging not only significantly reduces the quality of life for the elderly but also poses multifaceted challenges to society. Its progression involves the synergistic interaction of multidimensional, multipathway molecular mechanisms, including mitochondrial dysfunction, oxidative stress accumulation, chronic inflammation, and genomic damage. Quercetagetin (QG), as a natural flavanol monomer, exhibits significant potential in anti-aging due to its simultaneous targeting of key aging pathways such...
Myosin light chain kinase 2 and Myomesin 2 are related to the stiffness of vocal fold lamina propria in aging rats and humans
Vocal fold fibroblasts play an important role in the production of the extracellular matrix in the vocal folds. Myofibroblasts increase in the aging vocal fold lamina propria with increased alpha-smooth muscle actin. In addition to alpha-smooth muscle actin, various sarcomeric genes are expressed in myofibroblasts. However, there have been no studies on sarcomeric genes with myofibroblast differentiation in aging vocal folds. The purpose of this study was to analyze the changes and functions of...
Associations of BDNF methylation and rs6265 genotype with cognitive response to a six-month aerobic exercise intervention in women with early-stage breast cancer: results from the EPICC Trial
Women with breast cancer often experience cognitive decline, an accelerated aging phenotype. While aerobic exercise may mitigate this decline, effects are inconsistent by domains, and the molecular mechanisms remain unknown. Given the brain-derived neurotrophic factor (BDNF)'s responsiveness to exercise and role in cognition, we investigated BDNF methylation and rs6265, its functional SNP, with cognitive responses to aerobic exercise. Leveraging data from a randomized clinical trial which found...
Two-year evolution of frailty status and predictive factors in Chinese older adults: a national longitudinal study
CONCLUSION: The worsening of frailty with age is more common in older adults than the improvement of frailty. Among robust and pre-frail individuals, older women are more likely to experience a deterioration in frailty status. The factors influencing frailty transitions are multifaceted and complex. Therefore, when intervening in the progression of frailty among older adults, it is essential to comprehensively assess frailty risks and influencing factors based on the diverse characteristics and...
Accident-related deaths in the geriatric population: the role of chronic diseases and forensic investigations
CONCLUSIONS: In order to prevent accident-related deaths, it is important to take protective measures and facilitate access to emergency medical services for geriatric individuals, especially those with chronic diseases. This is particularly important for preventing traffic accidents in urban areas and firearm and animal attacks in rural areas. Examining the causes and risk factors of accident-related deaths in the older population can promote healthier ageing. This study provides important data...
Electron Microscopy and Multi-Omics Reveal Mitochondrial Dysfunction and Structural Remodeling in the Hearts of Elderly Mice
Aging is a key driver of cardiac dysfunction, promoting structural remodeling, metabolic alterations, and loss of cellular resilience. In aged hearts, extracellular matrix remodeling and collagen accumulation reduce ventricular compliance, impairing both diastolic function and stress adaptability. Cardiomyocytes exhibit diminished regenerative capacity and dysregulated stress responses, with mitochondrial dysfunction emerging as a central contributor to energy imbalance, oxidative stress, and...
2Innate immune signaling mediates differential acute and long-term outcomes of repeated vs. single TBI in Drosophila
Traumatic brain injuries (TBIs) are a global source of hospitalization, long-term disability, and death. However, age, sex, and other demographics differ widely among patients and the variable characteristics of TBIs further obscure injury outcomes. Here, we used Drosophila melanogaster to assess the effects of mild, repeated TBI (multi-day, MD) compared to single, severe TBI (single-day, SD). In all genotypes tested, flies given an SD injury exhibited higher acute mortality, but in some...
Immunolabelling and Micro-Computed Tomography Revealed Age-Related Alterations in 3D Microvasculature of Tendons
Tendon degeneration is common, and its risk increases with age both in humans and horses. Tendon regeneration and healing is limited due to inherent low cell density and vascularisation, and current treatments are insufficient as indicated by scar tissue formation and a high re-injury rate. The tendon vasculature plays a crucial role in tendon homeostasis, regeneration and healing, making it a potential therapeutic target. However, the effect of ageing on the tendon microvasculature is poorly...
