About Kailash Chadha


Dr. Chadha graduated from University of Guelph, Guelph, Ontario, Canada and completed his postdoctoral work as a fellow of National Research Council of Canada. He came to Roswell Park as Assistant Professor of Oncology in 1972 and later was promoted to Associate Professor of Oncology. He also holds a joint appointment as Research Assistant Professor in the Department of Medicine, the School of Medicine, State University of New York at Buffalo. His research interests are largely in the area of Interferons & Other Cytokines and role of Prostate Specific Antigen (PSA) in prostate cancer. Dr. Chadha has authored and co-authored more than 120 journal articles, several reviews and book chapters. He has also edited a book on Interferons and has four US Patents. He has also participated in several national and international meetings as an invited speaker.

Dr. Chadha has served as consultant with Hoffmann-La Roche in the area of Pegylated interferons. He has served on editorial board of several journals and has reviewed publication for several journals including Cancer Research, Clinical Cancer Research, Interferons, Virology, Neoplasia, Oncology, British J Cancer, Cancer Growth & Metastases etc. He has reviewed grants for American Cancer Society, NSF, Department of Veterans Affairs, and Biomedical Research Council etc. He has been major Thesis Advisor for several students for MS, and Ph.D. degrees. He has also served as Thesis advisor for MS and Ph.D. students both nationally and internationally. Dr. Chadha has actively participated in teaching several courses at Roswell Park including Interferons & Cytokines, Molecular Biology of Animal Viruses, Recent Advances in Biochemistry of Neoplasia, Histocompatibility and Immunobiology.

Research Overview:

Dr. Chadha’s research focus is in the area of interferons and role of PSA in angiogenesis in prostate cancer. Interferons are currently used in the clinic primarily for viral infections and in diseases like multiple sclerosis. However, a significant fraction of patients do not respond to this treatment. The mechanism of lack of this response is not known. We have identified circulating IIA protein in the blood of MS patients that is largely responsible for lack of response to interferon treatment. We are currently involved in further characterization of IIA.

Prostate-specific antigen (PSA) is currently used as a biomarker for early diagnosis and in the treatment of prostate cancer. However, this biomarker is neither disease-specific nor tissue specific. Use of this biomarker results in 70% false positive and 30% false negative results and is responsible for severe undesirable side effects in patients. We have identified a panel of biomarkers that will eliminate these drawbacks of PSA test. The earlier results need to be validated in a larger sample before FDA approval. Both in vitro and in vivo studies in animals we have shown that PSA has antiangiogenic activity and any loss of PSA in normal prostate due to disease condition promotes tumor growth.
