背景说明：Handle region peptide, rat 是肾素原 (prorenin) 受体拮抗剂，能够抑制糖尿病性肾病的进程，同时对眼部炎症有抵抗作用。Handle region peptide, rat is a prorenin receptor antagonist, suppresses the progression of diabetic nephropathy and has anti-inflammatory in the eye.
In Vivo：Handle region peptide, rat (0.1 mg/kg) suppresses leukocyte adhesion in the endotoxin-induced uveitis (EIU) retina, and decreases the leukocyte counts in rats. Handle region peptide, rat (0.1 mg/kg) lowers the protein concentration in EIU rats induced by LPS, and reduces the mRNA expression and the protein levels of inflammatory mediators such as ICAM-1, CCL2/MCP-1, and IL-6 in rats.
In Vitro：Handle region peptide, rat is a (pro)renin receptor antagonist. Handle region peptide, rat (1 μM) reduces the ratio of active to total ERK1/2. Handle region peptide, rat (0.1-1 μM) reduces TGF-β1 mRNA level, and inhibits the mesangial cells proliferation in a dose-dependent manner. Handle region peptide, rat (0.01-1 μM) increases the MMP-2 activity.
