Epigenetic Regulation of Cellular Senescence
Cells, 2022 Senescence is a complex cellular stress response that abolishes proliferative capacity and generates a unique secretory pattern that is implicated in organismal aging and age-related disease.

Cellular interactions in the tumor microenvironment: the role of secretome [PDF]
, 2019 Over the past years, it has become evident that cancer initiation and progression depends on several components of the tumor microenvironment, including inflammatory and immune cells, fibroblasts, endothelial cells, adipocytes, and extracellular matrix ...

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors
Advanced Science, EarlyView.Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

Oncogenic senescence: a multi-functional perspective. [PDF]
, 2017 Cellular senescence is defined as an irreversible growth arrest with the acquisition of a distinctive secretome. The growth arrest is a potent anticancer mechanism whereas the secretome facilitates wound healing, tissue repair, and development.

Advanced Science, EarlyView.Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Implications of Cellular Aging in Cardiac Reprogramming [PDF]
, 2018 Aging is characterized by a chronic functional decline of organ systems which leads to tissue dysfunction over time, representing a risk factor for diseases development, including cardiovascular.

Advanced Science, EarlyView.This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

Advanced Science, EarlyView.A dual‐targeting strategy to rejuvenate aged tendons. A reactive oxygen species (ROS)‐responsive hydrogel co‐delivers a selenium nanozyme (scavenges ROS) and a STING inhibitor to tendon stem cells. This combined action restores mitochondria–nucleus communication, alleviates cellular senescence, and rejuvenates tendon regeneration, offering a novel ...

Stem Cell Research, 2015 The role of serum amyloid A (SAA) proteins, which are ligands for toll-like receptors, was analyzed in human bone marrow-derived mesenchymal stem cells (hMSCs) and their osteogenic offspring with a focus on senescence, differentiation and mineralization.

Pericentromeric repetitive ncRNA regulates chromatin interaction and inflammatory gene expression
Nucleus, 2022 Cellular senescence provokes a dramatic alteration of chromatin organization and gene expression profile of proinflammatory factors, thereby contributing to various age-related pathologies via the senescence-associated secretory phenotype (SASP ...
