11β-羥基類固醇脫氫酶1型
外觀
11β-羥基類固醇脫氫酶1型(HSD11B1),也稱為可的松還原酶,是一種NADPH依賴性酶,在包括肝臟、脂肪組織和中樞神經系統在內的關鍵代謝組織中高度表達。在這些組織中,HSD11B1將可的松還原為激活糖皮質激素受體的活性激素皮質醇。屬於短鏈脫氫酶家族。
功能
[編輯]這個基因編碼的蛋白質是一種微粒體酶,催化應激激素皮質醇轉化為非活性代謝物可的松。此外,編碼的蛋白質可以催化相反的反應,即可的松轉化為皮質醇。過多的皮質醇會導致中樞性肥胖,這種基因的一個特殊變異與兒童肥胖和胰島素抵抗有關。在這個基因中發現了兩個編碼相同蛋白質的轉錄變體。[6]
臨床意義
[編輯]11β-HSD1被通常用於治療消化性潰瘍的藥物卡賓諾酮抑制。此外,從甘草(glycyrrhiza glabra)根中提取的18α-甘草酸被發現是一種抑制劑。[7]
水楊酸鹽下調肥胖小鼠脂肪組織中11β-HSD1的表達,從而解釋了阿司匹林改善2型糖尿病血糖控制的原因。[8]綠茶中的表沒食子兒茶素沒食子酸酯也能有效地抑制這種酶;[9]綠茶是多種酚類物質的複雜混合物,其含量隨着生產和加工的不同而變化,其中一些酚類物質是已知的改變遺傳表達的HDAC抑制劑。綠茶中的EGCG通常很難被血液吸收。需要更多的研究才能得出明確的結論。[來源請求]
