| Outline of Final Research Achievements |
Temporomandibular joint disease is epidemiologically more common in females, and blood estrogen concentrations in patients with temporomandibular disorder are reported to be significantly higher than those in patients without TMJ. Furthermore, since the blood estrogen concentration in patients with osteoarthritis correlates with the pathology of osteoarthritis, it has been suggested that estrogen is deeply involved in the pathogenesis of osteoarthritis. This study revealed that elevated expression of Cox-2 and MMP-3 by high concentration estrogen under conditions loaded with mechanical stretching stimulation is enhanced via the estrogen receptor ERα-NF-KB.
