Research Overview

Neurospecificity is a key factor in selective vulnerability in neurodegeneration diseases. The laboratory of Dr. Carol Miller has focused on identifying and characterizing the function of genes selectively expressed or regulated in vulnerable neurons. For example, one gene, JNK3, a neuron-specific stress kinase responds to environmental stress. Defining protein-protein interactions of these signal transduction molecules has led to underlying mechanism leading to cell death caused by hypoxia/ischemia of strokes or amyloid (AB peptides) of Alzheimer's disease. We have also identified several JNK interacting proteins, including one, DENN-MADD which functions in synaptic vesicle release but under stress, leads to apoptosis.

Because of cross-interactions of many of these signal transduction pathways, Dr. Miller's group is using microarrays which define regulation of multiple genes. We are combining these methods with isolation of single, normal or diseased neurons from human post-mortem brain and linear "in cell" amplification of the mRNA. Once normal neuronal subpopulations are characterized, we can compare those from diseased brains, including affected or spared subpopulations early or late in the course of the disease. Using bioinformatics, we are defining functionally related clusters of genes. We expect this approach to identify co-regulation of known genes and lead to the discovery of new genes. Our work links observations in experimental models to mechanisms operative in the normal and diseased human brain.
