品系介绍

MST1(Macrophage stimulating 1,巨噬细胞刺激因子1),又称肝细胞生长因子样蛋白(HGFL)或巨噬细胞刺激蛋白(MSP),是一种分泌型生长因子,属于kringle蛋白家族,与肝细胞生长因子具有同源性 [1-2]。其主要由肝脏表达,通过与受体RON(MST1R)结合,调控巨噬细胞的趋化、吞噬、形态变化及炎症介质产生,并在纤毛运动等生理过程中发挥作用 [3-4]。该基因的非同义编码变异rs3197999(R689C)与炎症性肠病(IBD,包括克罗恩病和溃疡性结肠炎)及原发性硬化性胆管炎(PSC)显著相关 [5-6]。
huMST1(2)小鼠通过基因编辑技术,将内源小鼠Mst1基因从5′UTR至3′UTR的序列替换为人源MST1基因从5′UTR至3′UTR的序列。其应用方向主要包括炎症性肠病(IBD)、原发性硬化性胆管炎、巨噬细胞相关炎症及免疫调控等的机制研究,以及靶向MST1/MSP-RON通路治疗方案的探索,可用于评估相关药物在炎症与免疫疾病中的潜在作用。

构建方案

将内源小鼠Mst1基因从5′UTR至3′UTR的序列替换为人源MST1基因从5′UTR至3′UTR的序列。该基因敲入(KI)区域可能影响小鼠Mir7088的表达,对小鼠Rnf123的影响尚不明确。
