Klotho衍生肽1(KP1)(56-87)是从人类Klotho蛋白质中衍生的肽,具有扰乱TGF-β信号传导的作用。它与TGF-β受体类型1(TGFBR2)和TGF-β受体类型2(TGFBR2;Kds分别为1.41和14.6µM)结合。KP1(10 µg/ml)的预孵育抑制TGF-β在NRK-49F大鼠成纤维细胞中诱导的纤维连接蛋白和α-平滑肌肌动蛋白(α-SMA)水平的增加。在体内,KP1(每天1 mg/kg)选择性地定位于受损的肾脏,并减少血清肌酐和血尿素氮水平,这些是肾功能的标志物,同时也减少了小鼠单侧输尿管阻塞(UUO)和单侧缺血-再灌注损伤诱导的肾脏纤维化模型中的肾纤维化。

产品描述 | Klotho-derived peptide 1 (KP1) (56-87), a peptide originating from the human Klotho protein, disrupts TGF-β signaling by binding to TGF-β receptor types 1 and 2 (TGFBR1 and TGFBR2; Kds = 1.41 and 14.6 µM, respectively). Preincubation with KP1 at a concentration of 10 µg/ml hinders the TGF-β-induced escalation of fibronectin and α-smooth muscle actin (α-SMA) levels in NRK-49F rat fibroblasts. Furthermore, in vivo studies reveal that KP1, administered at 1 mg/kg per day, preferentially accumulates in damaged kidneys, leading to significant reductions in serum creatinine and blood urea nitrogen levels, indicators of improved kidney function. Additionally, it decreases kidney fibrosis in mouse models of unilateral ureteral obstruction (UUO) and unilateral ischemia-reperfusion injury-induced renal fibrosis. |
