靶点 | Glucagon Receptor | |
In vitro(体外研究) | In human umbilical vein endothelial cells, exendin-4 significantly increases NO production, endothelial NO synthase (eNOS) phosphorylation, and GTP cyclohydrolase 1 (GTPCH1) level in a dose-dependent manner. Exendin-4 shows cytotoxic effects to MCF-7 breast cancer cells with IC50 of 5 μM at 48 hour. | |
In vivo(体内研究) | Both low- and high-dose exendin-4 treatment in ob/ob mice improve serum ALT and reduce serum glucose, insulin levels and calculated HOMA scores compared with control. Exendin-4-treated ob/ob mice sustain a marked reduction in the net weight gain in the final 4 weeks of the study period. Animals treated with exendin-4 have more pancreatic acinar inflammation, more pyknotic nuclei and weigh significantly less than control rats. Exendin-4 treatment is associated with lower insulin and leptin levels as well as lower HOMA values in rats. Exenatide causes dose-dependent relaxation of rat thoracic aorta, which is evoked via the GLP-1 receptor and is mediated mainly by H2S but also by NO and CO. | |
