High Throughput Screening Facility at the University of Iowa:
The University of Iowa High Throughput Screening Facility (UIHTS) is a high throughput platform that integrates robotics, detection systems and chemical /biologics libraries. UIHTS enables scalable screening approaches, not only to foster hit and lead generation for drug discovery and development through screening of systematic, unbiased large chemical/biologics libraries; but also to facilitate molecular probe discovery for mechanism of action (MOA) studies of chemical biology through screening of focused intellectually-designed compound collections. As a university core facility, UIHTS provides highly flexible screening services, project management, and assay/technology development for investigators across campus as well as off-campus.
UIHTS is equipped to perform high throughput screening (HTS) in 96, 384 and 1536-well formats with plate reader detection (Perkin-Elmer EnVision) using absorbance, fluorescence and luminescence, including advanced FRET and BRET techniques. UIHTS is also equipped to perform high content screening (HCS, Perkin-Elmer Operetta Confocal Imaging System) to detect and quantify phenotypic changes, i.e. cell differentiation, cell migration, neurite outgrowth, and target trafficking; or by fluorescence intensities for target protein expression, transcription factor or signaling pathway analysis. HTS and HCS systems are integrated with robotics for plate handling and assay execution, suitable for small- or large-scale compound library screens with “walk-away” levels of automation.
UIHTS holds two “small molecule” libraries. The Spectrum Library from MicroSource consists of 2320 structurally diverse compounds including marketed and experimental drugs as well as natural products. This array of test compounds provides a rigorous platform for assay validation and testing. The larger collection is from Chembridge, the Diverset, a collection of 50,000 small molecules representing a wide swath of chemical space, optimized to be “drug like,” considering factors such as partition coefficient and Lipinski-like rules. UIHTS is also building a UI legacy library with pure natural products and medicinal chemistry-focused compounds. In addition, UIHTS are also in the process of determining the need and feasibility of obtain a biologics library, i.e. genome-wide siRNA, antibodies, and diverse cell lines.
Overall, UIHTS is a laboratory core focused on scalable screening approaches for drug discovery and development and molecular probe discovery for mechanism of action (MOA) studies of chemical biology for investigators across campus and beyond.
The Prostate Cancer Research Program at the University of Iowa:
Another aspect of the environment for prostate cancer research at the University of Iowa is the Prostate Cancer Research Program. Salem is a member of the prostate cancer research program at the University of Iowa. Opened in 1991, as a result of common research interests, 17 members of the University of Iowa’s Departments of Anatomy, Biochemistry, Internal Medicine, Pathology, Pediatrics, Pharmacy, Preventive Medicine and Environmental Health, Radiology, and Urology, met to organize a Prostate Cancer Research Group. Each investigator either had previous research experience in prostate cancer or had expressed an interest in forging collaborations in a new field. Under the direction of our collabarator, Dr. Lubaroff, the group began meeting on a monthly basis to discuss the development of research collaborations. The research backgrounds of the investigators at that time included immunology, genetics, molecular biology, epidemiology, chemoprevention, radiation research, clinical urology, and chemotherapy. Monthly journal club meetings were also initiated to discuss pertinent papers in the field of prostate cancer. Support for the efforts of this group was strong from its inception.
The success of the Prostate Cancer Research Group has depended upon the interdisciplinary collaborations that have been forged in the eight years of its existence. There has been, and continues to be, a commitment from members of the group to maintain an active and productive research group in prostate cancer. Each member has contributed his or her expertise and insight into the problems associated with prostate cancer. The interest and direction of the group is predominantly that of laboratory research, although there is a significant clinical research component.
The environment created by the collaborations among members of the Prostate Cancer Research Program is one of support, collaborations, critical evaluations of research programs, and shared expertise. All of these factors aid in the continued success of prostate cancer research at the University of Iowa.
The Cancer Immunotherapy Group at the University of Iowa:
The Cancer Immunotherapy Group was founded to foster collaborations and translational science among the large number of investigators in the Holden Comprehensive Cancer Center whose research is devoted to cancer immunotherapies. There are 45 members from two colleges and 8 departments. The group meets monthly with informal presentations of immunotherapy research in the laboratories of members as well as discussion of new clinical trials, funding opportunities, and, of course the formation of new collaborations among members with diverse expertise in the field. At least two new grants have been submitted and approved as a result of the new collaborations.
