A Programmable Nanoreactor Orchestrates Cascade of DNA Sensing to Amplify cGAS‐STING Activation for Cancer Immunotherapy

Advanced Science, EarlyView.
A programmable nanoreactor was engineered for precise cGAS‐STING pathway activation in cancer immunotherapy. This strategy bridges targeted tumor DNA damage with DC immunomodulation, providing a translatable platform to unlock innate and adaptive antitumor immunity.

Correlation of telomere length in brain tissue with peripheral tissues in living human subjects

Frontiers in Molecular Neuroscience
Telomeres are important to chromosomal stability, and changes in their length correlate with disease, potentially relevant to brain disorders. Assessing telomere length in human brain is invasive, but whether peripheral tissue telomere length correlates ...

Intelligent Thermo‐Self‐Limited Magnetothermia with Heat‐Triggered TERT Silencing for Precision Synergetic Cancer Therapy

Advanced Science, EarlyView.
Telomerase reverse transcriptase (TERT) mRNA induces DNA self‐assembly in cancer cells, boosting the nanoplatform's magnetothermal properties. This magnetothermia then activates the Hsp70 promoter, initiating siRNA synthesis to silence the TERT gene, enhancing cancer treatment.

Vitamin E Supplementation—But Not Induced Oxidative Stress—Influences Telomere Dynamics During Early Development in Wild Passerines

Frontiers in Ecology and Evolution, 2019
Telomere length is a marker of cellular senescence that relates to different components of individual fitness. Oxidative stress is often claimed as a main proximate factor contributing to telomere attrition, although the importance of this factor in vivo

Extensive telomere erosion is consistent with localised clonal expansions in Barrett's metaplasia.

PLoS ONE, 2017
Barrett's oesophagus is a premalignant metaplastic condition that predisposes patients to the development of oesophageal adenocarcinoma. However, only a minor fraction of Barrett's oesophagus patients progress to adenocarcinoma and it is thus essential ...

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

Advanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

Telomeres in Space

Aging Cell
ABSTRACTRecent studies have reported that the spaceflight environment lengthens leukocyte telomeres. We propose that this baffling finding reflects changes in the composition of leukocyte subsets rather than an actual increase in telomere length within individual leukocytes.

Pan‐3D Genome Analysis Reveals the Roles of Structural Variation in Chicken Chromatin Architectures, Domestication and Production Traits

Advanced Science, EarlyView.
This study firstly presents a comprehensive and high‐resolution pan‐3D genome resource in chicken. Our findings reveal the role of structural variations in 3D genome architectures, and how they influence the domestication process and production traits at the 3D genome level.

Glutamine Deprivation Triggers Tribbles Homolog 3 Dependent G‐Quadruplex Resolution to Maintain DNA Repair and Tumor Survival

Advanced Science, EarlyView.
Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes
