| Outline of Final Research Achievements |
Recentrly, a new human pulmonary arterial hypertention (PAH)-like rat model, which mimic pulmonary vasculopathy in human PAH, was reported.Since estorogen has been implicated in the pathogenesis of PAH and epigenetic modification of gene expression, we examined the vascular lesion formation of PAH under the estrogen administration with the rats. In the group received the estrogen before exhibiting PAH, vascular lesions were suppressed, but not in the group received estrogen after exhibited PAH. We found that estrogen was involved in the pathogenesis of PAH and the timing of administration of estrogen was important.
We attempted to separate cultures of smooth muscle cells from each level of the lung vessel and established culture method. This enables the study of cell level to elucidate the pathogenesis mechanisms.
