Computational and experimental analysis of mitogenic signaling pathways
activated by oncogenic Ras. The Ras signaling cascade
constitutes a major pathway shown to be deregulated due to activating
mutations in 30% of all human tumors. The vast majority of mutations occur in K-ras. We use genetically engineered mice that harbor a conditional,
activatable K-ras allele as a model of human cancer.
