Project Title:The relationship between homologous recombination and chemotherapy sensitivity
Research Summary:Chemotherapy drugs such as cisplatin target DNA in cancer cells, but some cancers are resistant due to highly efficient DNA repair mechanisms. Enzymes called translesion synthesis (TLS) polymerases enhance DNA repair efficiency. We know that some types of breast cancer have high levels of TLS polymerases, and that some of these polymerases are regulated by tumour suppressor genes. We will therefore investigate how these tumour suppressor genes regulate TLS polymerases and how changes in the levels of TLS polymerases affects cisplatin resistance in breast cancer. Ultimately, determining the role of TLS polymerases in cisplatin sensitivity may reveal potential new targets to treat chemotherapy-resistant breast cancers.

After completing my graduate studies, I plan to pursue a career in the private sector. The field of genetics is moving ahead at an unprecedented pace due to technologies such as CRISPR. My goal is to be part of a biotechnology company that uses these exciting genetic technologies to tackle health challenges and advance our knowledge of the genome.
