Modeling of Acute Resistance to the HER2 Inhibitor, Lapatinib, in Breast Cancer Cells Marc Fink & Yan Liu Student Project Proposal Computational Cell Biology 2012

Motivation Observation during experiments: Lapatinib kills most cells but some of them can survive. Hypothesis: Secondary receptor pathways leads to cell survival. Goal: Regenerate the experimental results with mathematical model and find out the factors which influence the percentage of cell survival
