An HIV Protein Plays a Surprising Role in Gene Activation

...a—the authors show that what's true for yeast also holds for mammals, or at least for the human cell lines investigated here. Each effector was required for PIC assembly, which was in turn required to activate transcription. The big surprise came in the next round of experiments, which explored Tat's infl...

Purdue proves concept of using nano-materials for drug discovery

...rs created a chip about one centimeter square that holds thousands of tiny vessels sitting on top of a material that contains numerous pores. This "nanoporous" material makes it possible to carry out reactions inside the vessels. The goal is to produce "laboratories-on-a-chip" less than a half-inch square...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease
