Iron accumulation drives fibrosis, senescence and the senescence-associated secretory phenotype

Nature Metabolism, 2023
Abstract Fibrogenesis is part of a normal protective response to tissue injury that can become irreversible and progressive, leading to fatal diseases. Senescent cells are a main driver of fibrotic diseases through their secretome, known as senescence-associated secretory phenotype (SASP). Here, we report that cellular senescence, and

Senescence and SASP Are Potential Therapeutic Targets for Ischemic Stroke

Pharmaceuticals
Aging is a known co-morbidity of ischemic stroke with its risk and severity increasing every year past 55+. While many of the current stroke therapies have shown success in reducing mortality, post-stroke morbidity has not seen the same substantial ...

Loss of MECP2 Leads to Activation of P53 and Neuronal Senescence. [PDF]

, 2018
To determine the role for mutations of MECP2 in Rett syndrome, we generated isogenic lines of human induced pluripotent stem cells, neural progenitor cells, and neurons from patient fibroblasts with and without MECP2 expression in an attempt to ...

A Model for p38MAPK-Induced Astrocyte Senescence.

PLoS ONE, 2015
Experimental evidence indicates that aging leads to accumulation of senescent cells in tissues and they develop a secretory phenotype (also known as SASP, for senescence-associated secretory phenotype) that can contribute to chronic inflammation and ...

Non-Cell Autonomous Effects of the Senescence-Associated Secretory Phenotype in Cancer Therapy

Frontiers in Oncology, 2018
In addition to promoting various forms of cell death, most conventional anti-tumor therapies also promote senescence. There is now extensive evidence that therapy-induced senescence (TIS) might be transient, raising the concern that TIS could represent ...

Lysosome-mediated processing of chromatin in senescence [PDF]

, 2013
Cellular senescence is a stable proliferation arrest, a potent tumor suppressor mechanism, and a likely contributor to tissue aging. Cellular senescence involves extensive cellular remodeling, including of chromatin structure. Autophagy and lysosomes are

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Phenotypic and functional characterization of corneal endothelial cells during in vitro expansion. [PDF]

, 2020
The advent of cell culture-based methods for the establishment and expansion of human corneal endothelial cells (CEnC) has provided a source of transplantable corneal endothelium, with a significant potential to challenge the one donor-one recipient ...
