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 at Texas Children's Cancer and Hematology Center, and the Quantitative and Computational Biosciences Department, Therapeutic Innovation Center, and Dan L Duncan Comprehensive Cancer Center at Baylor College of Medicine.

Dr. Sumazin studies cancer systems biology, including technology development and its applications to cancer genomics. He’s contributed to comparative studies of cancers, studies of non-coding RNAs in cancer, and the design of diagnostic algorithms to optimize therapies for cancer patients. He helped design biochemical and computational technologies to resolve the composition and phylogeny of cancers, and he helped identify cancer clones that influence etiology, progression, and response to therapies.

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).
