Condylar Degradation from Decreased Occlusal Loading following Masticatory Muscle Atrophy

Figure 5

Protein fold change in cartilage after treatment. Western blot analysis of condylar cartilage. PTHrP and Ihh showed a similar declination after decreased occlusal loading treatment (b, c). The two extracellular collagens, Col2a1 and Col X, were more sensitive to the altered loading, which resulted in a dramatic decrease in the BTX group (d, e) (p<0.05;p<0.01;p<0.001).
