Histone methylation

An Existing Diabetes Drug May Treat Aspects of Aging

In the Nature publication Signal Transduction and Targeted Therapy, researchers have described how glibenclamide, a drug used to treat type 2 diabetes, partially reverses epigenetic alterations and fights cellular senescence

Fibroblasts

A Protein That Controls Senescent Cell Structure

Researchers publishing in Cellular Signaling have explained how the protein AP2A1 affects stress fibers that change with cellular senescence. Stress fibers Stress fibers naturally hold cells into their proper shape.

Need for Cholesterol May Explain Alzheimer’s Brain Patterns

Some brain regions are more vulnerable to Alzheimer’s disease than others. A new study suggests that this might be due to how they uptake cholesterol [1]. Why do some parts of the brain succumb earlier? Despite decades of research and vast amounts of funding, scientists still

Researchers Find New Target for Spinal Disc Degeneration

Researchers have found a new avenue for approaching spinal disc degeneration and published their work in Aging Cell. A very common problem Back problems in the elderly are widely known to be caused by a deteriorating spine. Some of these problems are due to the vertebrae

Heat May Speed Up Epigenetic Aging in Older Adults

A recent study reported significant associations between increased heat days and accelerated epigenetic aging [1]. Heat alters DNA While warm summer days on the beach are pleasant, extreme heat is not as enjoyable, especially in daily life. It is also not healthy, since extreme heat has

Alzheimer's disease

Anti-Amyloid Drug Reduces Alzheimer’s Risk in Small Subgroup

According to an open-label study from Washington University in St. Louis, the anti-amyloid drug gantenerumab reduced the risk of developing familial Alzheimer’s disease in a subgroup of participants [1]. Is it about amyloid beta? Despite billions of dollars invested in developing therapies against Alzheimer’s disease, the

Scientists Create Cytoskeleton-Like Structures From RNA

In a new study, researchers report producing self-assembling nanotubes and rings made from RNA molecules inside artificial cell-like lipid vesicles. In the future, this technology could facilitate the creation of synthetic cells for various research, diagnostic, and therapeutic applications [1]. Paperless origami DNA and RNA molecules

Hypothalamus

A Hypothalamus Neuropeptide Reduces Aging in a Mouse Model

Researchers have improved multiple health metrics in prematurely aged mice by re-establishing the production of neuropeptide Y in the hypothalamus [1]. An essential protein Age-related decline in the function of the hypothalamus, a core region of the brain, has been suggested to be a “key factor

Short-Term Overeating Alters Brain Insulin Sensitivity

A new study published in Nature Metabolism suggests that even a short period of eating loads of sweet and fatty snacks can cause brain changes reminiscent of those seen in obesity and type 2 diabetes [1]. What can go wrong in five days? If you usually

Elamipretide, a Potential New Drug, Reduces Frailty in Mice

In Aging Cell, Dr. Vadim Gladyshev and a team of researchers have described how elamipretide beneficially affects mitochondrial pathways and reverses frailty in mice. A drug on its way to the clinic As a mitochondria-affecting antioxidant peptide, elamipretide has been, and continues to be, the subject

Cellular Senescence Prevents Unlearning in Some Male Mice

In Aging Cell, researchers have established a link between cellular senescence and cognitive decline in unmodified male mice. Resilience versus decline The authors begin their paper by noting that cognitive decline in older people varies greatly. Some people suffer serious cognitive defects; other people are scarcely

Histone methylation

An Existing Diabetes Drug May Treat Aspects of Aging

In the Nature publication Signal Transduction and Targeted Therapy, researchers have described how glibenclamide, a drug used to treat type 2 diabetes, partially reverses epigenetic alterations and fights cellular senescence in mice. A system tightly tied together This paper begins with a discussion of the relationship

Lab mouse

A Klotho Gene Therapy Extends Life in Male Mice

In Molecular Therapy, a team of researchers has described how increasing the expression of a form of Klotho, a protein that has been frequently found to have rejuvenative effects, leads to longer lifespans in male mice. Klotho has various forms In their introduction, the researchers distinguish

Ginkgo biloba

Ginkgolide B Improves Healthspan and Lifespan in Female Mice

The authors of a recent study describe Ginkgolide B, a compound with senotherapeutic potential that improved muscle health, metabolism, frailty, inflammation, and senescence metrics and increased lifespan in female mice [1]. From East Asia to the clinic Ginkgolide B is a compound that can be extracted

Genes Affect Aging and Mortality Less Than Extrinsic Factors

A massive study from the University of Oxford has evaluated the relative impact of genetic and non-genetic factors on aging, mortality, and disease prevalence. A deeper dive The question of how strongly genes affect our longevity has been asked before, and the emerging answer is not

Fibroblasts

A Protein That Controls Senescent Cell Structure

Researchers publishing in Cellular Signaling have explained how the protein AP2A1 affects stress fibers that change with cellular senescence. Stress fibers Stress fibers naturally hold cells into their proper shape. They are made out of the common protein actin and linked together by α-actinin and a

Effects of Estradiol and Progesterone on Knee Osteoarthritis

Recent research has addressed menopause-related molecular processes that impact the high prevalence of knee osteoarthritis in post-menopausal women. Restoration of female sex hormones in a post-menopausal mouse model improved joint health [1]. A centuries-old observation The authors start the article with a quote from the English
