Signal Transduction & Cell Proliferation Research Program

  • Program Leader: Scott W. Hiebert, Ph.D.
    Co-Leader: Jordan D. Berlin, M.D.

Program Description

Scientific Goals
The Signal Transduction and Cell Proliferation Research Program is composed of a wide base of faculty committed to the investigation of cell growth control. A major goal of the program is to promote outstanding basic research in these areas and thus identify new growth control pathways that may be exploited for the development of novel therapeutic approaches. The program also provides basic science expertise upon which more translational programs within the Cancer Center can develop new approaches and understandings of particular cancers. Because of the diversity of pathways that regulate growth control, the Program membership is large and represents diverse interests within the signal transduction/cell proliferation area. This Research Program also brings together the study of humans, mammals, and model systems to allow a full understanding of the signaling pathways that control growth. The members include yeast geneticists, structural biologists, clinician-scientists, biochemists, developmental biologists, and cell and molecular biologists. However, the Program does maintain the primary overall focus of mitogenic signaling mechanisms and cellular transformation.

Specific Aims
The Program has two broad aims: 1) Increasing awareness of the research going on within each member’s laboratory and thereby encouraging collaborative interactions within the Program and 2) Providing the basic science expertise for translational approaches within the Cancer Center. For this latter goal, we have recruited Dr.Jordan Berlin to serve as Co-Leader of the Program. Dr. Berlin heads the Clinical Trials Office (CTO) within the Cancer Center and brings expertise in translating the observations in signaling to the clinic in several clinical trials.

Areas of Research Program Expertise

For the purpose of conceptual clarity, the research interests of the faculty in this Program can be classified and presented in four distinct but overlapping sub-areas or concentrations within the field of signal transduction. These are Growth Factors and their Receptors, Signal Intermediates, Gene Expression, and Cell Cycle Control. The research interests of program members follow the canonical signal transduction pathway from cell surface receptors, through signaling intermediates, into the nucleus to alter gene expression patterns and affect cell cycle progression, increase proliferation, affect apoptosis, and cause cellular transformation. The figure shown below illustrates a basic signaling pathway and indicates the general focus of each ST member, recognizing that many of our members work in multiple areas.
