INSTRUCTIONS - STUDENTS: You may receive this form by email, or you may download it after it has been posted here. Either way, print and review this form. Complete or correct the sections, from "Student's Name" to "Student's Level", and sign ("Student signature"). Ask your supervisor to sign her/his section near the bottom. Take it to the department* corresponding to the course number in Section A; this may or may not be your own department. (* EXCEPTIONS: For NSCI 396 and COGS 396, please bring it to the Interdisciplinary Programs Adviser in Dawson Hall.) Do not register for a '396' course on Minerva until you receive departmental permission. Have a discussion with your supervisor about time/work expectations, keeping in mind that this is a 3-credit course (roughly, 10 hours per week for 12 weeks). Remember that a '396' course is an elective.
INSTRUCTIONS - DEPARTMENTS: After the unit chair/director/designate approves (or not) this project, please notify student. If approved, please give student permission to register on Minerva, and send a copy of this form (with signatures) to the Office for Undergraduate Research in Science (either fax, or internal mail to Dawson Hall 408-A, or PDF scan + email).

Project title: Impact of targeted agents on oncosome profiles in cancer
Project description (50-100 words suggested): Cancer cells emit oncogene-containing extracellular vesicles (oncosomes), which act as biological mediators and reservoirs of molecular biomarkers reflective of malignant transformation. We hypothesize that successful obliteration of the respective oncogenic pathways with specific pharmacological inhibitors will be reflected in the emission profiles of these vesicles, including their numbers, types, and both content and state of activation (phosphorylation) of their corresponding oncoprotein targets. This notion will be tested in the A431 human epithelial cancer model system, which is driven by the oncogenic epidermal growth factor receptor (EGFR), and exquisitely responsive to EGFR inhibitors, such as CI-1033. The aims of this project is to perform nanoparticle tracking analysis of oncosomes emitted by CI-1033-treated and control A431 cells, and test them by Western blotting and ELISA assays for the content of EGFR and phospho-EGFR, as well as characteristics specific for distinct vesiculation pathways, including: Rab proteins, Alix, TSG101, HSP70 and flotilin. These experiments will illuminate the impact of prototypic anticancer targeted agents on tumor-derived vesicles that can be recovered from plasma of cancer patients and remotely reveal the effects of these drugs on oncogenic targets (liquid biopsy). This knowledge could contribute to development of novel biomarkers and companion diagnostics in cancer.
