Outline of Research at the Start

近年、長寿遺伝子として注目されている Sirt (sirtuin) が心筋保護に関与する可能性があると報告された。また、これらの心筋保護作用が、肥満や血糖値によって影響されることも明らかになってきた。つまり、Sirt は高血糖などの体内状態により動態・作用の変化が起こる可能性が示唆される。両者に関連があると考察するが、両者の関連についてはまだ明らかでない。
そこで本研究は、イソフルランの Sirt を介した心筋保護作用に対して、高血糖状態がどのような影響を与えるのかを解明することを目的とする。

Outline of Final Research Achievements

It was reported that Sirt (sirtuin), a longevity gene of interest, may be involved in myocardial protection. It has also become clear that these myocardial protective effects are affected by obesity and blood glucose levels. In other words, it is suggested that Sirt may undergo changes in its kinetics and action depending on internal conditions such as hyperglycemia. Therefore, the present study was designed to clarify the effect of hyperglycemia on the Sirt-mediated cardioprotective effects of the inhaled anesthetic isoflurane.

Academic Significance and Societal Importance of the Research Achievements

近年の食生活の欧米化、人口の高齢化、それに伴う生活習慣病の増加により、本邦での心血管リスクは急激に増加している。虚血性心疾患やリスクを有する患者の心合併症予防、その治療は患者予後にとって重要な因子となっている。
高血糖状態時の吸入麻酔薬・Sirt による心筋保護抑制作用の詳細な機序について検討していくことで、心筋虚血再灌流障害などによる細胞死に対する Sirt の生体内の役割が明らかになると思われ、社会的意義は大きいと考える。
