GSK3b mediates radiation-induced cytotoxicity in hippocampal neurons.

Major Goals: A formidable challenge in the treatment of primary and metastatic brain cancers, especially in children, is the long-term neurocognitive deficiencies resulting from cranial irradiation (IR)-induced hippocampal neuronal apoptosis. Our laboratory has discovered a novel functional connection between the metabolic kinase GSK3¿ and the Non- homologous End-joining (NHEJ) pathway that repair DNA double-strand breaks (DSBs).

The role of BRCA1 in nonhomologous repair of chromosomal double-strand breaks

Major Goals:  The long-term objective of this research is to understand the mechanisms that regulate the repair of chromosomal double-strand breaks (DSB), arisen during physiological processes or after ionizing radiation or chemotherapy. We aim to learn the impact of deregulated DSB repair on cellular mutagenic processes and genomic instability that promote carcinogenesis.
