King Molecular Biology Lab

Researching degenerative joint diseases


King
Karen B. King, PhD

Lab Director: Karen B. King, PhD

 

The long-term goals of the research in this laboratory are to elucidate the causes of the initiation and progression of osteoarthritis and other degenerative joint diseases and to create and improve treatment and prevention strategies. We take a multidisciplinary approach, using techniques from molecular biology, biochemistry, mechanobiology, cell biology, biomarker analysis, imaging, biomechanics, and tissue engineering.

We study in vivo cyclical joint loading using a novel animal model of repetitive finger joint flexion. Force and frequency are precisely controlled, and outcome measures include histological analysis of cartilage and bone morphology, biochemical, and spectral characterization of extracellular matrix components and analysis of mechanical properties. Using this model, we identified a significant increase in proteoglycan in the cartilage deep zone (measured using Fourier-transform infrared microspectroscopy). We also mesasured an increase in the number of chondrocytes producing osteopontin, a protein involved in mineralization.

The laboratory collaborates with the Musculoskeletal Disorders Lab in identifying inflammatory agents in soft tissue exposed to cyclic and static loading.
