The ability to obtain highly resolved molecular phenotypes directly from individual cells is transforming the way we define cell states and study cellular responses to\u0026nbsp;perturbations such as small molecules, cytokines and immunotherapies. Recent studies have shown that\u0026nbsp;intratumor heterogeneity influences the prediction of effective drug combinations. The increasing number of FDA approved targeted drugs and associated resistance mechanisms due to intratumor heterogeneity\u0026nbsp;warrants the need for a systematic and personalized combination therapy that will reduce the risk of drug\u0026nbsp;resistance and patient relapse. Drug combination prediction methods have mainly focused on targeting the\u0026nbsp;predominant tumor subpopulations. Single-cell technologies such as CyTOF reveal the heterogeneity\u0026nbsp;inherent in primary tissues and provide the means to characterize complex phenotypes, isolate rare populations and precisely target particular subpopulations. A key advantage of single-cell mass cytometry,\u0026nbsp;is that many surface and signaling markers can be simultaneously measured. The proposed research\u0026nbsp;provides a novel computational framework called DRUGNEM that can be used within a clinical setting to\u0026nbsp;integrate single-cell single-drug screening data for the purpose of identifying the optimal drug combination\u0026nbsp;that maximizes the treatment response across a heterogeneous population of cells based on intratumorsignaling\u0026nbsp;changes associated with a positive phenotype such as cell death measured by changes in specified death markers. DRUGNEM identifies sub populations of cells based on lineage markers and a nested drug network based on their effects on intracellular signaling markers that may be similar or different between these sub populations. Drug combinations that offer the maximal treatment response with the minimal number of drugs are ranked the highest. Using Bcr-Scr, JAK\/STAT and PI3k\/mTOR inhibitors,\u0026nbsp;DRUGNEM identifies different optimal regimens for each of the 30 Ph+ALL pediatric patient samples. Also,\u0026nbsp;from a theoretical perspective, my research provides preliminary evidence that synergy at the bulk\u0026nbsp;population level is different than aggregated across single cells.\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\n\u003Cbr \/\u003E\r\nHost:\u0026nbsp;\u003Ca href=\u0022mailto:maywang@gatech.edu\u0022\u003EMay Wang, Ph.D.\u003C\/a\u003E\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ETuesday, January 24\u003C\/strong\u003E\u003Cbr \/\u003E\r\n10:30 a.m.\u003Cbr \/\u003E\r\nMcIntire Room 3115,\u003Cbr \/\u003E\r\nWhitaker Bldg.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EVideoconference:\u003Cbr \/\u003E\r\nEmory: HSRB E182\u003Cbr \/\u003E\r\nGeorgia Tech: TEP 104\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"BME Speaker Seminar with Benedict Anchang Ph.D.*"}],"uid":"27513","created_gmt":"2017-01-18 18:45:33","changed_gmt":"2017-04-13 21:13:15","author":"Walter Rich","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-01-24T10:30:00-05:00","event_time_end":"2017-01-24T11:30:00-05:00","event_time_end_last":"2017-01-24T11:30:00-05:00","gmt_time_start":"2017-01-24 15:30:00","gmt_time_end":"2017-01-24 16:30:00","gmt_time_end_last":"2017-01-24 16:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"586126":{"id":"586126","type":"image","title":"Benedict Anchang, Ph.D.*","body":null,"created":"1484764656","gmt_created":"2017-01-18 18:37:36","changed":"1484764656","gmt_changed":"2017-01-18 18:37:36","alt":"Benedict Anchang, Ph.D.*","file":{"fid":"223389","name":"Benedict_Anchang.jpg","image_path":"\/sites\/default\/files\/images\/Benedict_Anchang.jpg","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/Benedict_Anchang.jpg","mime":"image\/jpeg","size":160444,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/Benedict_Anchang.jpg?itok=frFGzwkz"}}},"media_ids":["586126"],"groups":[{"id":"1254","name":"Wallace H.
