Research description

The research focus in the Valerie laboratory is on brain cancer and radiation-induced neurodegeneration resulting from DNA damage and repair. Much of the effort is spent on improving the treatment of malignant glioma and testing of small molecule inhibitors as radiosensitizers targeting the ATM kinase, the master regulator of the DNA damage response. ATM kinase plays a pivotal role in the decision-making between survival and death after radiation-induced DNA damage in both tumor and healthy brain but with opposite effect. ATM is required for neuronal cell death in the latter tissue whereas an ATM inhibitor radiosensitizes the tumor. Interestingly, ATM also plays an important role in the development of human neurodegenerative disease. To better understand this dichotomy we are using rodent models developed in the lab for studying neurodegeneration caused by radiation. More specifically, current projects include: 1. Ex vivo glioblastoma multiforme (GBM) tissue study: biomarker analysis of radiation-induced DNA damage signaling in tumor tissue resected from patients with GBM 2. Immune checkpoint inhibitor in combination with AZD1390 and radiation for GBM 3. Development of a porcine brain tumor model for therapeutic experimentation 4. DNA damage response and aberrant cell cycle reentry in neurodegeneration in a novel conditional knockout mouse model
