At the present time my research laboratory has two specific interests. The first is defining the molecular mechanisms governing the response of the retina to injury. We are using the methods of immunology, molecular biology, microarray technology and protein chemistry, to understand the response of the retina to injury and to define key regulatory elements. The functional roles of candidate proteins is tested in tissue culture models using AAV delivered siRNA and antibody perturbation as well as and intact animal models using transgenic methods. Currently we have identified to genetic networks that appear to regulate the susceptibility of neurons to death and regeneration of axons. Defining the genetic networks activated by injury will aid in understanding the mechanisms controlling promoting neuronal survival and axon regeneration.
The second major interest of the laboratory involves a novel molecule that selectively kills the most virulent form of brain cancer, glioblastoma. A chance discovery in collaboration with Dr. Duane Miller has led us to a point where we are testing the effectiveness of a specific compound in killing brain cancer. This finding has led to sever4al patents and the formation of a private incubator company.
