Suzanne Danhauer, PhD

 
I am a clinical health psychologist whose work has investigated potential benefits of behavioral and integrative medicine modalities with cancer patients and post-treatment survivors with an emphasis on symptom management. The primary focus of my research activities is patient-oriented clinical research. My research experience and current interests include the following areas: (1) the impact of behavioral interventions (e.g., yoga, physical activity) on symptoms, psychological function, and physical function with cancer survivors; (2) women’s health interventions, particularly the impact of mind-body interventions on hot flashes; (3) psychosocial functioning in cancer survivors with an emphasis on positive changes that are frequently reported during and after the cancer experience; (4) the impact of cancer survivorship on ability to work; and (5) the potential impact of psychological factors (e.g., worry, anxiety, depressive symptoms) on screening behavior and decision-making in cancer survivors or persons at risk for cancer.

Waldemar Debinski, MD, PhD

My laboratory focuses on molecular targeting for cancer treatment with emphasis on primary brain tumors. Our research is highly translational as we seek the means to improve the management of patients with brain tumors. We have uncovered a number of specific to malignant brain tumors plasma membrane receptors that can be utilized in their diagnosis/imaging/treatment. More recently, we have revealed intracellular signaling pathways that function abnormally in highly malignant brain tumors and represent attractive targets for therapeutic interventions. Thus, we are testing novel and potentially effective ways/agents to image and treat brain tumors exploiting their unique genotype and phenotype. One of these agents has already gone through the efficacy clinical trials and more are expected to enter the clinic in a foreseeable future.

Junjie Feng, PhD  

Dr. Feng is an Assistant Professor of Genomics and Personalized Medicine Research. He is a full member of the Center for Cancer Genomics. He has extensive training in a wide range of life science fields such as biochemistry, microbiology, genetics, molecular biology, cell biology, tumor biology, developmental biology, and pharmacology.  His research interests include 1) identifying aberrations in both the germline and the tumor genomes, and 2) dissecting the factors that associate with or cause these genomic abnormalities.  

Current Research: My current research focuses prostate cancer (PCa). A large number of men still die from this cancer every year, while the majority of men diagnosed with PCa will not die from the disease, and some may not even require treatment for their cancers.  Therefore, distinguishing aggressive from indolent forms of prostate cancer (PCa) is critical to eliminating death and torment from this disease.  I aim to identify the factors associated with PCa progression that leads to death of these patients, thereby allowing for the development of new biomarkers of prognostic and therapeutic significance for more effective management of this common disease.  Using high-resolution SNP arrays, my group has identified several biomarkers that are associated with aggressive and fatal types of PCa.  Collaborating with other scientists, we are currently using an integrated approach to uncover both genetic and epigenetic changes in both the germline genome and the tumor genome in order to dissect the mechanism(s) that lead to the death of patients with PCa.  If successful, the results from our research will help clinicians improve their ability to identify, at an earlier timepoint (i.e. time of diagnosis or surgery) a subset of patients that are most likely to develop aggressive PCa. The impact on treatment, quality of life, and cost may be substantial to both patients and society. 

Fang-Chi Hsu, PhD

Dr. Hsu is an Associate Professor in the Department of Biostatistical Sciences. Her methodological research interests are in the development of statistical methods in genetic association studies. She has worked actively on several ongoing genetic studies and co-authored more than 10 papers in the past several years. Dr. Hsu is a leading statistician for our research on risk prediction. Her research is focused on the design and analysis of genetic and aging studies.  She is interested in genetic risk prediction, gene-gene interaction analysis, and longitudinal data analysis.

Patrick P. Koty, MD

Patrick P. Koty, Ph.D. utilizes his knowledge of human genetics and expertise in cytogenetic, molecular cytogenetic, and molecular genetic approaches to investigate the process of carcinogenesis in the hope of developing protocols for the prevention of cancer.

Dr. Koty’s research interests includes investigating molecular mechanisms for the prevention of lung and breast carcinogenesis, in particular the genetically regulated pathways of programmed cell death (PCD). The PCD pathway is altered in most cancer cells resulting in resistance to chemotherapeutic agents that induce this process, thus, at least in part, explaining the ineffectiveness of current therapies.  Genes involved in the regulation of the PCD pathway are also altered in premalignant cells. Therefore, genetically manipulating these premalignant cells to reenter the PCD pathway may result in the prevention of cancer.   Dr. Koty investigates the role of several PCD regulatory genes (bcl-2, bax, and bcl-xL&S) in normal, premalignant and malignant primary tissues and established cell lines from lung and breast cancer patients. 

Another research interest of Dr. Koty involves investigating whether a common primary or secondary genetic lesion exists which leads to the development of lung or breast cancer.  The existence of such a lesion in premalignant tissue would thus provide a method to screen at-risk populations for the prevention of disease.  Dr. Koty uses various microarray platforms to investigate whether such early lesions occur in lung or breast cancer patients.

Wennuan Liu, PhD

Prostate cancer (PCa) is the most commonly diagnosed malignancy in men in the US.  A large number of men die from this cancer every year, while the majority of men diagnosed with PCa will not die from the disease, and some even may not require treatment for their cancers.  I am interested in identifying the factors associated with PCa progression that leads to death of the patients, thereby new markers of prognostic and therapeutic significance can be developed for more effective management of this common disease.The first phase of our research is to contemplate a comprehensive survey for the changes of DNA in the tumor genome using high resolution SNP arrays.  We have identified several biomarkers that associated with aggressive and fatal type of PCa.  Collaborating with other scientists, we are currently using an integrated approach to uncover both genetic and epigenetic changes in both germline and the tumor genome in order to dissect the mechanism(s) that leads to dead of patients with PCa.

Guangchao Sui, PhD

1. Generally, I am interested in how aberrant epigenetic regulation can mediate the initiation, development and progression of cancers. I am focusing on YY1-regulated pathways, including Mdm2-mediated p53 degradation and Ezh2-mediated histone methylation.

2. Specifically, I am investigating how YY1 expression can affect prostate cell proliferation in vitro and prostate cancer development/progression in vivo. I am also interested in breast cancer and microRNA studies and want to extend my research area to these fields.

3. I am interested in the functional study of microRNAs and their regulation in prostate cancer development. Especially, I want to identify the regulatory roles of microRNAs that are frequently deleted in prostate cancer.
