Tufts University chemist earns prestigious award for promising research on drug development

scription factors, which are in charge of turning genes on and off. "Cancer involves cell growth pathways that are getting turned on when they should be off," says Kritzer, and thus many transcription factors are known to be overactive in human cancers. For his research Kritzer will target three transcription factors implicated in cancer -- Myc, STAT3 and HSF1.

Kritzer can use yeast cells not only to make the cyclic peptides but also to sift through them to find those that inhibit these critical cancer proteins. In this manner, Kritzer notes, "we can screen up to 50 million new molecules for activity in living cells in a single week."

These new molecules will then be used as tools to understand how transcription factors contribute to cancer and other diseases. They may even form the basis for designing drugs that target these important but overlooked proteins.
