Researchers have created a deep learning-based biomarker, SASP Score, that evaluates the combined effects of the senescence-associated secretory phenotype (SASP) circulating in the bloodstream. Measuring an overall burden Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they...

Researchers have gone into deep detail regarding how each of five senescent brain cell types expresses and receives factors that encourage other cells to become senescent. The contagion of age Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part;...

Researchers have found that bound pieces of RNA and DNA in the cytoplasm of senescent cells encourage these cells to secrete inflammatory factors. When transcription gets sticky As part of the transcription process that produces necessary proteins, RNA must chemically interact with DNA. When it binds to DNA and integrates itself into the genome, it...

In Aging Cell, researchers have described the differences between primary and secondary senescent cells, comparing radiation-induced senescence to senescence induced by the senescence-associated secretory phenotype (SASP). Heterogeneity on top of heterogeneity Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are...

In Aging Cell, researchers have reported that chromatin demethylation allows SASP compounds to be more easily expressed. Chromatin and gene expression Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they emit potentially harmful chemical signals, collectively known...

A recent study investigated senescence in mouse and human skeletal muscle tissue. The authors demonstrated that the antiviral drug maraviroc reduces senescence and improves muscle health in aged mice [1]. Aging muscle tissue Senescent cells are one of the hallmarks of aging. One of their key characteristics is the presence of the senescence-associated secretory phenotype...
