Research recently published in Aging shows how senescent cells overreact to inflammatory stimuli, causing them to excessively excrete compounds that promote inflammation. The researchers hypothesize that this is one cause of the cytokine storm, an immune overreaction that is more common in the elderly and is known to cause severe dysfunction and even death when...

Researchers have developed a new transcriptomic aging clock that incorporates information about biological pathways. With this approach, the clock predicts not only age but also how the state of various genetic pathways changes with age, providing insight into the transcriptional changes involved in aging. Time for a new kind of clock In recent years, the...

New research has identified a set of long noncoding RNAs involved in inflammaging and the senescence-associated secretory phenotype (SASP) [1]. These RNAs are conserved across a range of species, including humans, and may prove a valuable avenue for controlling senescence. Age-related RNAs RNA can broadly be divided into protein-coding RNAs and noncoding RNAs, which have...

A new study in Molecular Cell has shown that the benefits of hypoxia may be derived from a suppression of the inflammatory SASP. Why we 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; instead, they emit potentially...

The results of a recent study suggest that fisetin appears to reduce the development of bleomycin-induced pulmonary fibrosis [1]. Fisetin is a plant polyphenol and part of the flavonoid group in the flavonol sub-category. The earliest record of isolated fisetin dates back to 1833 from the smoke bush (Rhus cotinus). Its basic chemical characteristics were...

Back in 2005, Drs. Irina and Michael Conboy showed that joining the circulatory systems of young and old mice together in a procedure called parabiosis could rejuvenate aged tissues and reverse some aspects of aging in old mice. Following this discovery, many researchers concluded that there must be something special in young blood that was...
