| Research Abstract |
To clarify the regulatory roles for the functional network of placenta on maintenance of homeostasis during normal pregnancy, I used full genome expression profiling to characterize the placenta of pregnant mice at a molecular level. The dynamic changes in the expression levels of metabolism- and neoangiogenesis-related genes were identified. On the other hand, in human, it is assumed that pregnancy-induced hypertension (PIH) is resulting from the breakdown of the pregnancy homeostasis. In this study, I showed that pregnancy-associated hypertensive (PAH) mice, which were previously generated in our laboratory, exhibited the pathological condition including the criteria of PIH. In addition, by evaluating the ameliorative properties of the antihypertensive drugs in PAH mice, I demonstrated the effectiveness of blockade of AT1, a receptor of vasopressor angiotensin II, on prevention of this pregnancy-related disease.
