Exercise Found to Have Anti-Senescence Effect

A new review paper delivers evidence that exercise, a powerful anti-aging tool, may be a natural senolytic [1]. Progress in the field of senolytics has been mixed. After the initial

Senolytics Reduce Gut Inflammation in Mice

A few years ago, a team at Mayo Clinic led by Dr. James Kirkland treated mice with the cancer drug dasatinib and the popular dietary supplement quercetin, with results suggesting

Groundbreaking New Therapy for Progeria

A gene editing technique published in Nature has proven to be effective in a mouse model of Hutchinson–Gilford progeria syndrome (HGPS). A single error causes tremendous damage HGPS is a

New Discovery in How Stem Cells Protect Telomeres

Scientists have discovered a new telomere-protecting mechanism in embryonic stem cells. This discovery can bring us closer to solving the notorious problem of telomere attrition and to understanding the immortality

Senescent Cells Recruit Sympathetic Nerves

Researchers publishing in Frontiers of Aging Neuroscience Journal have discovered a new way in which senescent cells contribute to aging and chronic disease.

Exercise Found to Have Anti-Senescence Effect

A new review paper delivers evidence that exercise, a powerful anti-aging tool, may be a natural senolytic [1]. Progress in the field of senolytics has been mixed. After the initial hype that had spawned dozens of startups, enthusiasm has waned somewhat in the wake of the

Arterial Stiffening Correlates With Cognitive Decline

Today, we want to highlight the results of a recent long-term study, which collected data over a four-year period to investigate the link between aortic stiffening and cognitive decline, including dementia. During aging, our blood vessels become increasingly stiff and lose their flexibility, and the cells

Senolytics Reduce Gut Inflammation in Mice

A few years ago, a team at Mayo Clinic led by Dr. James Kirkland treated mice with the cancer drug dasatinib and the popular dietary supplement quercetin, with results suggesting that the combination was able to destroy senescent cells. This combination was part of the first

Groundbreaking New Therapy for Progeria

A gene editing technique published in Nature has proven to be effective in a mouse model of Hutchinson–Gilford progeria syndrome (HGPS). A single error causes tremendous damage HGPS is a well-known disease that causes visible aging and early death in children. In progeria, the lamina that

A Cause of Genomic Instability Discovered

Research further illuminating the mechanisms of impaired DNA damage repair associated with aging has recently been published in the journal Aging. DNA damage repair is reduced as we age  While we have multiple mechanisms for repairing genomic damage, one type of damage, double-strand breaks, is particularly

Fisetin May Be Useful in Treating Pulmonary Fibrosis

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

Stem Cell Growth Factors Treat Alzheimer’s in Aged Mice

A new article published in Aging and Disease has taken a look at what two stem cell-activating growth factors can do in aged mice with Alzheimer’s-like pathology. Alzheimer’s disease (AD) is perhaps the most age-related of all age-related diseases. Perhaps not coincidentally, it has also been

MYSM1 Prolongs Lifespan by Regulating DNA Repair

New research has shown that a DNA repair gene modulates lifespan in mice [1]. This may serve as a therapeutic avenue or at least open the way towards dissecting the links between DNA damage and senescence. MYSM1 is a gene that removes a molecular mark known
