Outline of Final Research Achievements

The mechanism for pulmonary arterial hypertension (PAH) and its complication, right-sided heart failure is unknown. Using cDNA array analyses in the right ventricular tissues in the rats with monocrotaline-induced pulmonary hypertension, we have focused TMEM100, which is 20kD protein located in endo-cyto plasmic reticulum. Interestingly, TMEM100 expression is upregulated in cultured human umbilical arterial endothelial cells by BMP9/10, specific ligands for ALK1/BMPR2 receptors, recognized as causative genes for PAH by the linkage analysis in familial PAH. Thus, it is expected that TMEM100 is involved in the pathogenesis of PAH and its complication, right-sided heart failure.
Because of mice lacking the tmem100 gene is embryonic lethal, we generated inducible knockout mice of the tmem100 gene. Unfortunately, in spite of several experimental pulmonary arterial hypertension models, we have not found the evidence that TMEM100 is involved in the pathogenesis of PAH.
