New UK study shows potential for targeting aggressive breast cancers
Date:2/11/2014

4 to these genomic regions, Twist accelerates cell growth and invasion by "waking up" the expression of these oncogenes.

Additionally, the study showed that two BRD4 inhibitors, JQ1 and MS417, can specifically disrupt the interaction of Twist with BRD4, resulting in the suppression of invasion, stem cell-like characters and tumorigenicity of triple-negative breast cancer cells.

"This finding has significant clinical ramification, because drugs that can target the Twist-BRD4 interaction provide a new hope for treating life-threatening triple-negative breast cancer," said Zhou, associate professor of molecular and cellular biochemistry at UK.

Jian Shi, a post-doctoral fellow at UK Markey Cancer Center, was the first author of this study, and other collaborators include UK Markey Cancer Center director Dr. Mark Evers and researchers Chi Wang and Haining Zhu. Previously, Zhou and his team have studied the role of the Snail complex also known as the cellular "brake" in contrast to Twist's accelerant in the EMT program.
