Research Summary

Ionizing radiation is a mainstay of therapy for most types of cancer. The DNA strand breaks, crosslinks, adducts and DNA replication intermediates that are caused by ionizing radiation and many other therapeutic agents trigger activation of a complex network of intracellular signaling molecules that ultimately control cell growth and cell death. Employing recently developed technologies, the Bunz laboratory studies the signaling molecules and pathways that are activated by DNA damage. The goal of this work is to better understand how current therapies work, and to develop new and improved cancer treatments.
