This detailed book explores techniques for further elucidating the peripheral and central roles of oxytocin as well as techniques key to oxytocin receptor-related drug discovery. The first set of chapters explore this neuropeptide s peripheral and central effects, such as regulation of myometrial contraction, induction of cardioprotective effects, and the facilitation of pro-social behaviors. The book then continues by delving into a comprehensive pharmacological characterization of oxytocin receptor ligands and ligands of other key receptors such as the vasopressin receptor family. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
