Scientists have revealed a mechanism that causes heart cells to age and identified a drug that can rejuvenate them, according to a study published in eLife.  The drug is now in clinical trials. The results provide the first direct evidence that aging increases proton leakage in heart cells. The findings […]

Senescent cell accumulation is an important cause of degenerative aging. Senescent cells cease replication and begin to secrete an inflammatory mix of signals that disrupt tissue structure and function. These cells are created constantly, largely as a result of somatic cells hitting the Hayflick limit on cellular replication, but also […]

A combination approach to treating a prevalent glioma subtype — including metabolic reprogramming, radiation, chemotherapy and immunotherapy — led to a complete regression of tumors in 60% of study mice, new research by the University of Michigan Rogel Cancer Center found. The findings, which appear in the Journal of Clinical Investigation, support the testing […]

Systemic sclerosis is an autoimmune disease associated with inflammation and fibrosis, or scarring, that affects organs including the skin, heart, kidney and lungs. This form of scleroderma, this tightening and thickening of the skin, is a progressive, orphan illness that affects approximately 80,000 Americans and has no clear pathogenesis or FDA […]

Chronic inflammation grows with age throughout the body, characterized by increased levels of numerous inflammatory signal molecules, among which is IL-6. One contributing factor to the chronic inflammation of aging is the accumulation of lingering senescent cells, which rouse the immune system via secreted molecules that include, prominently, IL-6. Researchers […]

Children who undergo cataract surgery as infants have a 22% risk of glaucoma 10 years later, whether or not they receive an intraocular lens implant. The findings come from the National Eye Institute (NEI)-funded Infant Aphakic Treatment Study, which today published 10-year follow-up results in JAMA Ophthalmology. NEI is part […]

Fractured sleep, daytime sleepiness and other signs of disturbance in one’s circadian rhythm are common complaints of people with Alzheimer’s disease, and the problems only get worse as the disease progresses. But the reason for the link between Alzheimer’s and circadian dysfunction is not well understood. Researchers at Washington University […]

Ribosomes are the machines in the cell that use instructions from mRNA to synthesize functional proteins. There are hundreds of thousands of ribosomes in each cell, and they mostly process their instructions faithfully. But sometimes ribosomes get stuck or stall on roadblocks along with defective mRNA molecules. New research from […]

Researchers here note a study population in which glucosamine use correlates with a reduction in mortality risk that is of a similar size to that associated with exercise. One always has the suspicion that, even after controlling for such things, the use of less common supplements is just a marker […]
