Frail woman
A research paper published in Aging explored a link between breast cancer, hematopoietic cell transplants (HCTs), an increase in physical frailty, and cellular senescence. Treatment comes at a cost HCTs and breast cancer treatment are lifesaving procedures. However, chemotherapy in breast cancer sharply increases p16INK4a, a key biomarker of cellular senescence [1], and HCTs are...
More sand
Juan José Alba-Linares and his research team have published a preprint study that examined why different animals age at different rates. They found that epigenetic changes over time could explain why some animals live longer and estimated an upper limit for mammalian lifespan [1]. A problem of noise Why We Age: Epigenetic AlterationsEpigenetic alterations are...
100th birthday cake
Researchers are keeping a bank of induced pluripotent stem cells (iPSCs) derived from centenarians and their descendants. They describe the purpose of this bank and its uses in Aging Cell. A category of their own Centenarians don't merely live for a hundred years; they spend more time in good health (healthspan) than other people. This...
Cellular reprogramming
Dr. Belmonte’s group at Altos Labs targeted stressed and senescent cells with partial reprogramming, producing large increases in lifespan in male mice [1]. What are they doing there? Since the discovery of cellular reprogramming almost two decades ago, a lot of hopes have been put into this technology, and a lot of progress has been...
Stopwatch
Researchers publishing in Aging have found that fibroblast growth factor 21 (FGF21), an apparently beneficial protein naturally produced by the human body, heralds a greater likelihood of death. Multiple documented benefits FGF21 plays crucial roles in the human body. Secreted by the liver and many other tissues, it is responsible for glucose maintenance and fat...
Cynomolgus monkeys
In a new study, metformin, which has already shown good results in rodents and in human epidemiological studies, alleviated multiple signs of aging in male cynomolgus monkeys [1]. Now in monkeys Metformin, a well-established anti-diabetes drug, has been touted as a possible geroprotector since a study suggested that diabetes patients on metformin outlived age-matched healthy...
