Mechanisms of TMZ-associated Hypermutation in Glioma

Tumor recurrence is the leading cause of cancer mortality. We have shown that low-grade gliomas treated with the chemotherapeutic drug temozolomide follow an alternative evolutionary path to glioblastoma. Upon recurrence, these TMZ-treated tumors were hypermutated and harbored driver mutations in key tumor suppressors and oncogenes. We are currently researching the mechanism driving hypermutation in glioma and developing model systems to study somatic hypermutation.
