An interesting report from the Harvard Gazette on some research into a possibility of reducing some of the effects of aging, specifically aging of the heart:
Two Harvard Stem Cell Institute (HSCI) researchers — a stem cell biologist and a practicing cardiologist at Brigham and Women’s Hospital — have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for the form of age-related heart failure that affects millions of Americans.
When the protein, called GDF-11, was injected into old mice, which develop thickened heart walls in a manner similar to aging humans, the hearts were reduced in size and thickness, resembling the healthy hearts of younger mice.
Even more important than the implications for the treatment of diastolic heart failure, the finding by Richard T. Lee, a Harvard Medical School professor at the hospital, and Amy Wagers, a professor in Harvard’s Department of Stem Cell and Regenerative Biology, ultimately may rewrite our understanding of aging.
Research of this type may be very important as the baby boomer generation enters retirement age … not necessarily to extend total lifespan, but to increase the chances for healthy activity longer into our existing lifespan. Few of us would want to live to 100 if the last 20 years are pain-wracked, immobile, and inactive … but being able to live that long and managing to keep doing the things we like to do for most of that time? That’d be much more appealing to many of us.
