BIOE 201Final Project Introduction Tuesday, Sept. 23, 2014
Angiogenesis (neovascularization) growth of new blood vessels from pre-existing microvasculature • Physiologic angiogenesis • development • exercise • wound healing • female reproductive organs • Over 70 angiogenesis-dependent diseases • Cardiovascular disease • Breast Cancer Non healing ulcer & gangrene - from H.Gornick, Cleveland Clinic
Anti-angiogenic therapies Bevacizumab (Avastin; Genentech): VEGF antibody Ziv-aflibercept(VEGF Trap/Zaltrap; Regeneron): VEGF antibody Sunitinib (Sutent; Pfizer): Tyrosine kinase inhibitor (TKI) Sorafenib (Nexavar; Bayer & Onyx Pharmaceuticals): TKI • Avastin is approved for the treatment of: • Glioblastomamultiforme: most prevalent form of brain cancer • Metastatic colorectal cancer (colon cancer) • Non-small cell lung cancer • Metastatic kidney cancer • Several side effects: • Gastrointestinal perforation • Impaired wound healing • Bleeding • HTN
Some patients are intrinsically resistant to anti-angiogenic drugsAZD2171/Cediranib/Recentin Phase II clinical trial detects decreased tumor enhancement in over 50% of patients Best responding patient: • Decreased tumor size • Decreased vessel size • Decreased permeability Poorly responding patient • No change in tumor size • No change vessel size • No change in permeability Batchelor et al (2007) Cancer Cell

Systems biology can be used to examine signaling through receptors
Final project • Develop a systems biology approach for determining how to best target the VEGF-VEGFR signaling axis in angiogenesis. • Using the tools learned in Module 1: Mass Balances: • Systemically examine how signals enter cells (ligand-receptor binding) • How they generate cellular response (second-messenger signaling) • How these signals can be best targeted by drugs (mAbs, small molecules, etc.).
Goals • Determine angiogenic disease you want to treat. • Create a mathematical model simulating VEGF-VEGFR ligand-receptor reaction network in this disease. • Determine which molecule or molecules you will target within the VEGF-VEGFR reaction network. • Quantitatively evaluate the effectiveness of your strategy via model. • Demonstrate the value of your quantitative analytical framework by using it to compare your strategy to current drugs.
Deliverables • Mid-Semester Project: (presentation and 5 page progress report) • Tuesday, October 14, 2014 (Teams 1-3) • Wednesday, October 15, 2014 (Teams 4-10) • Final Project: (presentation & report): • Tuesday, December 2, 2014 (Teams 8-10) • Wednesday, December 3, 2014 (Teams 1-7)
Mid-Semester Project Report • Importance of VEGF pathway in disease • Ligand-receptor dynamics • Second messenger signaling pathways • Prior modeling • Approach • Preliminary results • Next steps
Mid-Semester Project Report • Importance of VEGF pathway in disease: Your group’s disease of interest. What therapies are currently available to treat this disease? • Ligand-receptor dynamics: What are the VEGF ligands? What are the VEGFRs? Where are these receptors located? What are the kinetics of binding (on/off rates)? • Second messenger signaling pathways: Which downstream molecules are activated by the VEGF-VEGFR axis?
Mid-Semester Project Report • Prior modeling: Do other models exist that focus on this pathway? If so, which ones, and what did they identify? • Approach: What will you model? How will you do it? • Preliminary results: any simulation results • Next steps: what you need to bring it all together

Rules for good ppt presentations Use University of Illinois templates: • http://identitystandards.illinois.edu/graphicstandardsmanual/othermedia/powerpoint.html • Many template options…
Rules for good ppt presentations • Font sizes should be 18+ • Font type should be a sans-serif (e.g., Arial, Calibri) • Font color should follow the theme • Check speling and grammar¡ • Headings should be descriptive • Animations should be tasteful • Bullet points imply a list and should not be alone…they’re when not in community w/ other bullet points • Color pictures should have a dark background • Cite EVERYTHING

Graphs have a professional appearance Good Graph What to check… Label axes Font type and size 18+ Use scales that make sense (usually start @ 0) Data points/Line graph (colors/style) Simple colors Enclose data with axes Origin preferred graphical software (free @ webstore)
How to prep a bad graph Bad Graph Reasons No label on axes Missing axes Unprofessional font Unreadable font size X-axis has too many increments Scale does not represent data well Unprofessional data points/Line graph (colors/style)
Next Steps • Teach you modeling! • Bring your laptop to class tomorrow and Friday • Download Matlab onto your laptop (along with Simbiology toolbox): webstore.illinois.edu
