Study Outlines Why Aging May Predispose to Fibrotic Diseases

A new study from UAB highlights why fibrotic diseases — diseases that feature fibrosis or scarring of organ tissue — are typically associated with aging. Fibrosis, the formation of fibrous scar tissue in response to injury, is part of the normal healing process. In young animals or people, scars resolve or fade away over time and are replaced by newly grown healthy tissue. In older subjects, the scars do not resolve or fade, and scar tissue can build up. In organs such as the heart, lungs, kidneys or liver, the buildup of scar tissue can interfere with normal function, with potentially devastating results. In findings published in Science Translational Medicine, the UAB team describes the mechanism that contributes to persistent fibrosis in the aged, and suggests targets that may help reverse the buildup of scar tissue.

Green Is Good

Using a screening method that previously identified a compound in apple peel as a muscle-boosting agent, a team of University of Iowa scientists has now discovered that tomatidine, a compound from green tomatoes, is even more potent for building muscle and protecting against muscle atrophy.

Monkey Caloric Restriction Study Shows Big Benefit; Contradicts Earlier Study

The latest results from a 25-year study of diet and aging in monkeys shows a significant reduction in mortality and in age-associated diseases among those with calorie-restricted diets. The study, begun at the University of Wisconsin-Madison in 1989, is one of two ongoing, long-term U.S. efforts to examine the effects of a reduced-calorie diet on nonhuman primates.

Cancer Chemotherapy Accelerates ‘Molecular Aging’

Physicians have long suspected that chemotherapy can accelerate the aging process in patients treated for cancer. Using a test developed at UNC Lineberger Comprehensive Cancer Center to determine molecular aging, UNC oncologists have directly measured the impact of anti-cancer chemotherapy drugs on biological aging.
