Fat Mice Help Georgia Regents University Study Heart Issues
An audio version of this story.
Building muscle helps fight the cardiovascular issues that plague many overweight people, according to findings from Georgia Regents University.
The university is using a $2.2 million grant to research obesity-related heart problems.
And chubby rodents are helping with the data.
The study from Georgia Regents University’s Vascular Biology Center includes obese and average-weight mice. As part of the research, the doctors deleted a regulator of muscle growth for both sets of mice.
The findings show the fat mice benefited from an increase in muscle mass.
“Their ability to dilate their blood vessels to open up blood flow to critical organs is markedly improved. Their blood pressure is improved and their erectile function is improved,” said Dr. David Stepp, a biologist at GRU.
The study is designed to confirm all the benefits of muscle building and is expected to take about five years.
