A scientist thought he may have discovered a new plant compound that would lower blood pressure in people. In his first experime
nt, he injected one hundred mice with the compound and found that the blood pressure in ninety-five of the treated mice was not affected. However, all of the mice seemed to grow at a faster rate then the control group. Which statement describes the most likely outcome of this investigation? The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug. He will develop a second experiment to find a way to make the drug successfully lower blood pressure in mice. The data he collected will be used in new investigations to determine why certain people are taller than others. He will use these results to conclude that the drug will most likely lower blood pressure in five percent of people.
According to the experiment, the drug which is discovered by the scientist as a blood-pressure lowering drug, is actually working as a growth-stimulant as most of the treated mice grew with a faster rate. Thus, the scientist can use this information to use that drug for a new use, as growth-stimulant.
The first experiment of the passage shows that treatment with TGFBR1 and TGFBR2 antagonists led to lower levels of epithelial cell production. For this conclusion to be strongly valid, we want to show a positive correlation between TGFBR activity and epithelial proliferation.
