Mouse Genetics

Although testing candidate gene variants in zebrafish is rapid and can provide insight into gene function and biology and  identify common pathways linked to a disease, there are limitations to studying OA per se in zebrafish. 

To address some of the limitations of studying OA in zebrafish, we use the mouse to study the mammalian synovial joint and to introduce specific human disease alleles into the orthologous mouse genes. Generating a mouse model harboring a human disease allele is important to: 1. Define the functional significance of candidate disease causing alleles discovered in human studies, 2. Establish causal mechanism of action and 3. Identify disease modifying therapeutic treatments.

Other projects in the lab:

1. Rotator Cuff Repair and Healing (human genetics, rodent models, and therapeutics). Collaboration with Drs. Tashjian and Chalmers.

2. Genetics and biology of Kienböck’s Disease (or avascular necrosis of the lunate).

3.High-throughput drug screens to identify compounds that modify activity of disease pathways.
