Physiology and Pharmacology of BRS-3 (Bombesin Receptor Subtype-3)

作为我们阐明BRS-3激动剂作用机制的研究的一部分，我们有初步数据表明BRS-3激动剂通过刺激棕色脂肪组织增加代谢率。 这些研究正在得到证实和扩大。 我们还在研究BRS-3在血压控制中的作用。 为了研究BRS-3作用的特定细胞、位点、组织和递质，我们产生了以下工具：1）条件性敲除floxed Brs 3小鼠，2）具有Brs 3驱动的Cre重组酶的敲入小鼠，和3）具有Brs 3驱动GFP表达的BAC转基因小鼠。 开发和验证这些工具所需的长期投资预计将在未来几年产生巨大回报。 我们正在与默克公司合作，使用选择性BRS-3化合物（特别是激动剂MK-5046和MK-7255）。 此外，在我到达NIDDK之前，我在默克研究实验室参与的BRS-3工作继续得到指导直至出版。

As part of our studies to elucidate the mechanism of action of BRS-3 agonists, we have preliminary data that BRS-3 agonists increase metabolic rate via stimulating brown adipose tissue. These studies are being confirmed and expanded upon. We are also investigating the role fo BRS-3 in blood pressure control. In order to study the specific cells, sites, tissues, and transmitters by which BRS-3 acts, we are generating the following tools: 1) a conditional knockout floxed Brs3 mouse, 2) a knockin mouse with Cre recombinase driven by Brs3, and 3) a BAC transgenic mouse with Brs3 driving GFP expression. The long-term investment required to generate and validate these tools is expected to yield great rewards in future years. We are collaborating with Merck, using selective BRS-3 compounds (particularly the agonists MK-5046 and MK-7255). Additionally, work on BRS-3 that I was involved with at Merck Research Laboratories prior to my arrival at NIDDK continues to be guided through to publication.
