Betatrophin——新型胰岛素激素
Betatrophin( 也被称为RIFL、Lipasin 或者Angiopoietin-likeprotein8 (ANGPTL8))是新发现的分泌蛋白,有198 个氨基酸,在小鼠体内可以促进β 细胞增殖、提高葡萄糖耐受性,此外可能也有抑制脂肪酶活性、调节血清中甘油三酯的功能。Betatrophin 在小鼠的肝脏、白色脂肪与棕色脂肪中表达;而在人的肝脏中高效表达。Betatrophin 水平在胰岛素抵抗与妊娠时会显著升高。虽然Betatrophin 的机制还不明确、它的受体还有待发现,但是这个激素可以控制β 细胞增殖,对于治疗糖尿病是否开启了一扇新的大门?
