可溶性鸟苷酸环化酶激活剂Cinaciguat对高糖环境下人脐静脉内皮细胞的保护作用
Protective Effects of Soluble Ornithine Cyclase Activator Cinaciguat on Human Umbilical Vein Endothelial Cells under the Condition of High Glucose
摘要
Abstract
OBJECTIVE:To study the protective effects of soluble ornithine cyclase activator cinaciguat(called CIN for short) on human umbilical vein endothelial cells (HUVECs) under the condition of high glucose. METHODS:HUVECs were treated with glucose 33.3 mmol/L to induce oxidative stress injury model. HUVECs were divided into normal group,high glucose group and high glucose+CIN 0.01,0.1,1 and 10 µmol/L groups. The cell viability was detected by MTT assay,and the survival rate of cells was callulated. Besides,HUVECs were divided into normal group,normal+CIN 1 µmol/L group,high glucose group,high glucose+CIN 1 µmol/L group. MDA content and SOD activity were determined by TBA method and xanthine oxidase method;mRNA expression of ICAM-1 and VCAM-1 were determined by RT-PCR. RESULTS:Compared with normal group,survival rate decreased in high glucose group(P<0.05);compared with high glucose group,that increased in high glucose+CIN 0.01,0.1,1 and 10 µmol/L groups,in concentration-dependent manner;there was no statistical significance in survival rate between high glu-cose+CIN 1 µmol/L group and high glucose+CIN 10 µmol/L group (P>0.05). Compared with normal group,MDA content and mRNA expression of ICAM-1 and VCAM-1 increased in high glucose group,while SOD activity decreased(P<0.05);above indi-cators had no significant change in normal+CIN 1 µmol/L group(P>0.05). Compared with high glucose group,MDA content and mRNA expression of ICAM-1 and VCAM-1 decreased in high glucose+CIN 1 µmol/L group,while SOD activity increased(P<0.05). CONCLUSIONS:CIN can protect high glucose-induced HUVECs injury in vitro. The mechanism may be associated with in-hibition of oxidative stress and inflammatory response.关键词
