Researchers from the University of Aberdeen have undergone drug trials using mice. They tested a new drug, "Trodusquemine" which supposedly reverses the effects of Atherosclerosis. Atherosclerosis is the buildup of fatty plaque inside of arteries. It can cause heart attacks, strokes, and many other cardiovascular problems.
In preclinical trials, the researchers were able to conclude that mice with set-in atherosclerosis, had less fatty plaque in their arteries. No matter how many doses a mouse was given, one, or multiple, the conclusion is the same. Still less fat in their arteries.
The drug works by inhibiting an enzyme PTP1B, which in diabetes or obese patients, is more prevalent.
