The work in Dr. Zuo's laboratory is focused on the identification and characterization of genes important for the development and degeneration of cerebellar Purkinje cells and inner ear hair cells. They are taking two complimentary approaches. The first, positional cloning of mouse mutant genes, takes advantage of recent advances in the mouse genome project. Mouse cerebellar mutants, such as lurcher (Lc), Purkinje cell degeneration (pcd) and nervous (nr), are of particular interest. They have identified and characterized the Lc gene and established genetic and physical maps of pcd and nr loci. As the mutant pcd gene induces Bcl-2 dependent apoptosis, they are searching for downstream genes involved in the degenerative process in pcd mutant mice. The second approach takes advantage of a new technique that allows modification of endogenous genes in bacterial artificial chromosomes (BACs) with a green fluorescent protein (GFP) reporter gene and further introduction of modified BACS into pronuclei to generate trans-genic mice with labeled neurons in the developing brain. They have chosen to modify three genes that have been shown to be expressed specifically in hair cells of the inner ear: alpha-9 AchR, Brn3.1 and delta-1 GluR. These transgenic mice will provide a resource for the construction of hair cell specific cDNA libraries at different developmental stages, as well as a tool for the introduction of exogenous genes into hair cells in vivo and for making hair cell specific knockout mice.
