    Description

    Exendin-4 (Exenatide), a 39 amino acid peptide, is a long-acting glucagon-like peptide-1 receptor agonist with an IC50 of 3.22 nM.

    IC50 & Target

    IC50: 3.22 nM (glucagon-like peptide-1 receptor)[1]

    In Vitro

    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[2]. Exendin-4 shows cytotoxic effects to MCF-7 breast cancer cells with IC50 of 5 μM at 48 hour[3].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    In Vivo

    Both low- and high-dose exendin-4 treatment in ob/ob mice improve serum ALT and reduce serum glucose, 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[4]. 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 leptin levels as well as lower HOMA values in rats[5]. 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[6].

    Animal Administration
    [4][5]

    Rats: 20 Sprague-Dawley male rats, ten of which are treated with exendin-4 (10 μg/kg) and ten of which are used as controls. The study period is 75 days. Serum and pancreatic tissue are removed for biochemical and histological study. Blood glucose, amylase, lipase and adipocytokines are compared between the two groups[5].

    Mice: The exendin-4 treatment groups are treated with 10 μg/kg every 24 hours for the first 14 days. This treatment is the induction phase. Respective control mice (lean and ob/ob) receive saline every 24 hours. After 14 days Exendin-4-treated mice are randomly divided into two groups: one group receives high dose exendin-4 (20 μg/kg) every 12 hours, while the second group continues with low dose exendin-4 (10 μg/kg) every 12 hours. The control mice continue to receive saline every 12 hours. The mice are weighed daily for the 60-day treatment period[4].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
