Key words: Genomic/Genetic instability; ATM Gene therapy; Animal models;

Genomic instability is a key event of cancer. To preserve genomic stability cells have developped systems to detect and repair DNA double strand breaks (DSBs).DSBs occur in response to exogenous agents, such as chemoterpeutics and during physiological processes as during normal DNA replication, meiotic recombination and lymphocytes maturation. If DSBs are not promptly repaired can be substrates for aberrant chromosomal translocations, which promote cancer.The focus of our research is to restore the function of ATM (Ataxia Telangiectasia Mutated) kinase that through an elaborate signal transduction system, has been established as a central player in DNA DSBs repair and genomic integrity preservation.

Ataxia Telangiectasia (A-T) is an inherited disease caused by a fault in the ATM gene that ultimately leads to death before the forties. The disease affects several body systems and causes neurodegeneration, immunodeficiency, sterility, radiosensitivity, lymphomas and leukemia predisposition. Moreover, missense mutations in ATM kinase domain are also found in many type of cancers, such as leukemia, lymphomas, breast, pancreas and gastric cancers but their impact on ATM function and implications for cancer therapy are largely unknown.

We aim to insert a correct version of ATM gene by lentiviral transduction and to edit ATM point mutations by the CRISPR/CAS9 strategy in human A-T cell lines and hematopoietic progenitor cells of ATM defective mouse models. Re-establishing ATM expression, we expect the rescue of immunological defects and the delay/prevention of thymoma in ATM deficient mice. Moreover, we expect to understand the specific role of ATM kinase activity and its essential targets indispensable for genomic stability maintenance.
