During his seminar, he will present three projects. \u003Cbr \/\u003E\u003Cbr \/\u003E(1) A biophysical study of Notch signaling. The Notch signaling mechanism is peculiar in that it requires competent endocytosis in the ligand cell. The Botvinick lab uses optical tweezers to argue Notch signaling is dependent on specific endocytic components and the generation of \u2018strong\u2019 endocytic forces. Additionally, they have strong evidence that receptor-ligand bond strength is independent of ligand endocytosis and recycling. \u003Cbr \/\u003E\u003Cbr \/\u003E(2) Optical Microrheology. The Botvinick lab uses optical microrheology to map ECM mechanical properties surrounding cells cultured in 3-D. They combine this with a shear gradient device to test the role of local stiffness in cell differentiation and function. \u003Cbr \/\u003E\u003Cbr \/\u003E(3) Micro-tsunamis. This is a new all-optical tool for the study of mechano transduction. The Botvinick lab uses a single focused laser pulse to excite mechano-signaling in hundreds of cells. Botvinick will demonstrate the utility of micro-tsunamis for the detection of drug-induced changes in cellular mechanotransduction.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EElliot Botvinick, PhD, assistant professor at University of California - Irvine, will give a seminar at the Petit Institute.\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Petit Institute Seminar - Elliot Botvinick, PhD - Columbia University"}],"uid":"27224","created_gmt":"2012-10-16 15:44:11","changed_gmt":"2016-10-08 02:00:42","author":"Megan McDevitt","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-10-23T12:00:00-04:00","event_time_end":"2012-10-23T13:00:00-04:00","event_time_end_last":"2012-10-23T13:00:00-04:00","gmt_time_start":"2012-10-23 16:00:00","gmt_time_end":"2012-10-23 17:00:00","gmt_time_end_last":"2012-10-23 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.ibb.gatech.edu\/","title":"Petit Institute for Bioengineering and Bioscience"}],"groups":[{"id":"1292","name":"Parker H.
