Colin Duckett, Ph.D

Colin Duckett, PhD.
Director of Program Development, North Campus Research Complex
Professor, Departments of Pathology and Internal Medicine

Dr. Duckett's laboratory is interested in studying how cells respond to internal and external cues, for example by undergoing a programmed form of cell death known as apoptosis, by modulating gene expression, or through the induction of proliferation. In normal cells these pathways are very tightly controlled, but one or more are deregulated in virtually all human diseases. Our specific interests are the study of a group of mammalian proteins called IAPs (Inhibitors of Apoptosis) which have collectively been shown to participate not only in apoptosis, but in intracellular signaling leading to transcriptional changes, as well as cellular proliferation and, most recently in copper homeostasis. Much of his current research is focused on the role of IAP proteins in cancer, especially prostate and breast cancer, with a particular emphasis on the potential of IAP antagonists as therapeutic agents, and additionally his lab is examining the role of specific IAPs in homeostatic regulation of lymphoid cells.

Related to their work on IAPs, the Duckett lab is also interested in studying the signaling pathways employed by the cell surface receptor, CD30, which is highly overexpressed in cells of Hodgkin's Disease origin, as well as certain non-Hodgkin's lymphomas including anaplastic large cell lymphoma. CD30 is an attractive target for these classes of lymphoma, because its expression is normally highly restricted in the body. Dr. Duckett is very interested in understanding the cellular effects of CD30-mediated signaling, especially as these signals are transduced through certain members of the IAP family, and his lab is most interested in examining the potential for this pathway to be exploited for therapeutic goals.

Elizabeth R. Lawlor, MD, PhD.

Elizabeth R. Lawlor, M.D., PhD.
Associate Professor, Department of Pathology
Associate Professor, Department of Pediatrics and Communicable Diseases

Dr. Lawlor's research focuses on studies of Ewing sarcoma, a very aggressive bone and soft tissue tumor that primarily affects children, adolescents and young adults. She is pursuing studies with stem cells in order to understand how the EWS-FLI1 oncogene can turn normal stem cells into Ewing sarcoma cells. In addition, her lab studies the contribution of epigenetic deregulation to the pathogenesis of cancer. Specifically, they are elucidating the contribution of polycomb gene deregulation in the origin and progression of Ewing sarcoma and determining how altered expression of the polycomb protein BMI-1 affects response to therapeutic agents. By evaluating the similarities and differences between normal stem cell development and cancer, the Lawlor lab is gaining insights into both the origins of pediatric sarcomas and the biology of cancer stem cells.

Mats Ljungman, PhD.

Mats Ljungman, PhD.
Professor, Radiation Oncology
Professor of Environmental Health Sciences, School of Public Health

Dr. Ljungman's lab is assisting with the examination of ATDC in DNA damage response. Over-expression of ATDC results in increased proliferation both in vitro and in vivo and leads to increased radiation resistance. The collaboration has found that ATDC is rapidly phosphorylated by the ATM kinase following irradiation and this leads to the re-localization of ATDC to sites of DNA damage. The lab is currently further investigating the mechanisms by which ATDC stimulates proliferation and protects cells from ionizing radiation and are screening for compounds that inactivates ATDC.

Sunitha Nagrath, Ph.D.

Sunitha Nagrath, PhD.
Assistant Professor, Chemical Engineering

Dr. Nagrath's lab is developing microfluidic devices for isolating and studying cancer cells as related to metastasis.

Metastasis occurs when cells disseminate from the primary tumor site and travel through the body's vasculature, then exit the vessels into distant tissues, adapt to the microenviroment and proliferate into new tumors.

She is using microfluidic devices to study cell migration, specifically how cancer cells enter and exit the vasculature, detecting circulating cancer cells in the blood, and studying the microenvironmental cues needed to sustain and grow tumor metastases.

Microfluidic devices allow for studying individual cell behavior, capturing rare cells, such as circulating tumor cells (CTCs), and sustaining cell cultures. Microfluidics are being created to mimic in vivo environments and will become more widely used in biology as the devices become more automated for general use.

Nouri Neamati, PhD

Nouri Neamati, PhD.
Professor, Department of Medicinal Chemistry

Dr. Neamati's lab uses computational chemistry to match chemical compounds to biological processes in an effort to design novel drugs and therapeutics. Focusing on small-molecule design, Neamati's research aims to find compounds that will fit into active sites in proteins and enzymes to inhibit their expression.

A small-molecule drug works by binding to a target, usually a specialized protein in a disease cell. Before computational chemistry technology was available, researchers had to design or test a compound derived from a natural product, inject it into mice or patients, and then wait to observe the results. This process was slow, expensive and comparatively ineffective. Now, while in vitro testing saves both time and money, sifting through a library of some 10 million compounds still presents a daunting time-consuming drug development process.

Neamati's computational platform allows him to pursue, through a rational selection process that predicts which compounds are likely to inhibit a particular protein, some fifty-thousand compounds to move to the next step in drug discovery. Then, using mathematical and statistical analysis to cluster these compounds into families, Neamati can test one compound from each family under the assumption that they embody properties of other members of the family. Once a compound of interest is identified, he can examine the whole family of compounds to find the optimal match for a specific target.

Another approach to drug design used in the Neamati lab is based on the structure of the target protein. Neamati uses technology that can design a compound that fits nicely on the active site of a protein, like a lock and key. Using the structural knowledge already available on vast numbers of existing drugs and targets, Neamati proceeds by either building a compound based on a known drug or a compound based on the target.

Neamati's work primarily focuses on cancer and HIV. He currently has compounds at various stages of development - from theoretical to in vitro to in vivo. Some of these compounds have been shown to work in experimental mouse disease models while exhibiting no toxicity. Collaborating with colleagues at the TOP, Neamati aims to take these promising therapeutics into phase 1 clinical trials.

He has also led efforts within the UMCCC to expand these findings into other tumor types. U-M researchers were first to discover stem cells in pancreatic and head and neck cancers and are focusing on cancer stem cells in virtually every cancer type, including colon, lung and thyroid tumors.

Dr. Wicha is also active as a clinician, specializing in the treatment of breast cancer patients. He has served as chairman of the board of the Association of American Cancer Institutes and as past chairman for the National Cancer Institute's Cancer Center Support Review Committee.

Dr. Wicha joined the University of Michigan Medical Center in 1980. From 1984 to 1993, he served as chief in the Division of Hematology/Oncology in the Department of Internal Medicine. Dr. Wicha received his medical degree from Stanford University and trained in internal medicine at the University of Chicago. He then went on to the National Cancer Institute, where he trained in clinical oncology and cancer biology.
