This publication contains the proceedings of Relaxin 2000: The Third International Conference on the Hormone Relaxin & Related Peptides , held on October 22-27, 2000, at the Cable Beach Resort, Broome, Australia. Delegates from academia and industry who attended this meeting, the latest in an irregular series, participated in an exciting scientific program that covered all aspects of current relaxin research, the growth of which in recent years has been stellar. Seminal topics presented at the conference and in this book include: clinical roles for relaxin, elucidation of novel sites of action of the hormone, relaxin-induced signal transduction, identification of non-pregnant roles of the hormone, and of novel relaxin-related peptides (particularly insl 3 and 5) and their possible synergistic actions with relaxin. Audience: This book will be of considerable interest to both endocrinologists and protein researchers, including those engaged in studies in members of the insulin super-family.
