Research Statement

Dr. Pavel Sumazin is Director of the Bioinformatics Core Laboratory and a member of the Cancer Genetics and Genomics Program and the Center for Precision Oncology.

Dr. Pavel Sumazin interprets molecular profiles of human tumors to inform cancer diagnostics and therapeutics. He aims to infer pathophysiological consequences of somatic and germline alterations by mapping out amplification and propagation pathways that channel their effects to alter the activity of cancer genes. Towards this goal, he has helped reverse-engineer transcriptional and post-transcriptional regulatory networks in multiple human cancers, identifying genes that regulate cell survival and proliferation, DNA damage response, and cancer progression. Specifically, Dr. Sumazin has helped identify a molecular signature to distinguish indolent from aggressive prostate cancer (Irshad, 2013), a tumor suppressor tRNA-derived microRNA in B cell lymphoma (Basso, 2009; Maute, 2013), genes that target tumor-suppressors PTEN and RB1 through competition for microRNA regulation in glioblastoma (Sumazin, 2011), and transcription factors that regulate proliferation in germinal centers (Lefebvre, 2010; Basso, 2010).
