Research Interests

The goal of the Brain Cancer Biology and Therapy Laboratory (Riggins Lab) is to locate the genetic and genomic changes that lead to brain cancer. The technologies we employ search large portions, or entire cancer genome, for cancer-causing DNA changes. The molecular changes are evaluated for how they contribute to cancer development. The alterations discovered are mutations, amplifications and abnormally expressed genes. Our goal is to find the critical new molecular functions that the tumor gains and determine quickly if counteracting the mutation can slow or kill cancer cells, including cancer stem cells. We are using this information to develop better brain cancer therapy. This is done in part by screening drug and chemical libraries to identify small molecules that kill mutation containing cancer cells. Animal models are used to test possible new anti-cancer compounds.
