New research published in Aging has analyzed the telomeres of patients hospitalized due to COVID-19. Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand base pairs, yet they consist of repetitions of a single sequence: TTAGGG. Telomeres do not code for proteins, but they protect chromosomes...

Alpha-ketoglutarate (AKG) is a popular dietary and sports supplement frequently used in the bodybuilding world, but interest in this molecule has more recently reached the aging research field for its potential to slow down aging. AKG is a naturally occurring endogenous intermediary metabolite, which means that our own bodies create it, and is part of...

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 of cancer cells [1]. Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand base pairs, yet...

Recently on Lifespan.io, we reported the rather overhyped findings of a study that presented hyperbaric oxygen therapy as an effective way to reverse human aging. The Sheekey Science Show offers its own explanation on this study and the reactions of multiple media publications to it.

An international collective of scientists has discovered a new cellular process: telomere transfer from antigen-presenting cells to T cells that boosts the latter's lifespan and proliferative potential [1]. Telomere AttritionTelomeres are DNA regions located at the ends of a chromosome. Their normal length is 8-10 thousand base pairs, yet they consist of repetitions of a...

The Journal Club returns August 25th at 13:00 EDT live on our Facebook page where Dr. Oliver Medvedik will be taking a look at the new study by Dr. Maria Blasco from the CNIO, which shows that telomerase therapy can address fibrosis in normally aged mice and not just mouse models of the disease. Short/dysfunctional...
