 Project objective

Genome editing has enriched our understanding of mechanisms of the human pathology. Genome editing took a significant advance with the recent development of the CRISPR-Cas9 technology. CRISPR is an acronym for: Clustered Regularly Interspaced Short Palindromic Repeats and it is an adaptation of a prokaryotic functional system. It uses a single guide RNA to direct Cas9 activity to a specific part of the genome, therefore, this system can be used for gene editing and regulation. Cancer is a genetic disease where some DNA-damaged cells begin to divide without stopping and spread into surrounding tissues. Interestingly, in some tumors, there is a dependency of a single oncogenic activity (oncogene addiction). This phenomenon indicates that mutations in key oncogenes (driver mutation) are able to drive carcinogenesis and maintain the tumor phenotype. Suggestively, if we can prevent or disrupt these mutations, we can difficult carcinogenesis or damage an established tumoral phenotype. In this proposal, we seek out for using Crispr-Cas9 technology to target driver mutations and evaluate its therapeutic and preventive value. To develop a proof of concept, we will focus on lung cancer driven by KRAS mutations. The generating of a transgenic mouse expressing Crispr-Cas9 designed to target the mutation Kras C12C will allow us to test the potential cancer-resistant phenotype and raise the concept of Genetic Vaccines.
