High-throughput screening in academia: the Harvard experience.

To identify small-molecule modulators of biologic systems, academic scientists are beginning to use high-throughput screening (HTS) approaches that have traditionally been used only in industry. The HTS laboratories that are being established in universities, while differing in details of staffing, equipment, and size, have all been created to attain 1 or more of 3 principal goals: drug discovery, chemical genetics, or training. This article will examine the role that these activities play in 4 HTS laboratories that have been created within the academic community of Harvard Medical School and its affiliated institutions. First, the 3 activities will be defined with special attention paid to describing the impact they are having on how academic biologic science is conducted today. Next, the histories and operations of the 4 Harvard laboratories are reviewed. In the course of these summaries, emphasis is placed on understanding the motivational role that the 3 activities initially played in the creation of the 4 Harvard facilities and the roles that the activities continue to play in their day-to-day operations. Finally, several concerns are identified that must be attended to for the successful establishment and operation of an academic biologic science that has yet to be fully determined. HTS has the ability to provide the tools to test previously untestable hypotheses and can thereby allow the discovery of the unanticipated and the truly novel.
