Several models have been put forth for how cellular sequences are acquired by retroviral genomes; Figure 22-7A summarizes these models. Proto-oncogenes drive the cell cycle, which is the process cells go through before they can divide. Pancreatic inflammation accelerates mutant Kras-driven tumorigenesis in mice, suggesting high selectivity in the cells that oncogenic Kras transforms, although the mechanisms dictating this specificity are p. kinase domain. The low-affinity nerve growth factor receptor gene is another proto-oncogene that has a prognostic effect similar to Trk-A and probably influences cellular maturation. The KRAS gene is in the Ras family of oncogenes, which also includes two other genes: HRAS and NRAS. In one scenario, a retrovirus integrates into the host cell genome just upstream from a protooncogene.
