Outline of Final Research Achievements

Increased expression of glucokinase (GK, MODY2) and PAI -1, was observed in the liver of osteonectin (SPARC) -overexpressing mice. The known major MODY forms a closely linked network of transcription factors that is linked to insulin secretion failure, and SPARC has been found to belong to this "pancreatic islet functional network". On the other hand, an increase in liver weight, probably due to an increase in triglyceride content, a decrease in fasting and casual blood glucose, and an improvement in glucose tolerance were also observed. A metabolic link between "Increased hepatic glucose uptake or reduced glucose release independent of pancreatic hormones (insulin and glucagon)" and "Hypoglycemic induced lipolysis and migration to the liver" by the pancreatic humoral factor SPARC was suggested.

Academic Significance and Societal Importance of the Research Achievements

2型糖尿病に肥満の合併は高頻度であり、発症予防や治療において体脂肪の減量は重要である。特に、心血管イベントのリスク軽減では、高血糖と過体重の双方の改善が求められる。従って、インスリン分泌能の回復のみならず、2型糖尿病で障害されているインスリン・グルカゴン作用に依存しない、効率的な血糖降下と体脂肪減が同時に見込める膵液性因子SPARC治療は理想的であり、特に高齢化社会では高いニーズが見込める。
さらに「分泌蛋白」はヒトにおいて血中測定や投与が比較的容易であるので、臨床応用に展開しやすい利点があり、SPARC経路は糖尿病治療薬の創薬対象になると期待される。
