title: Promising future for the transgenic rat in transplantation research.
abstract: The rat is the most widely used animal species in surgical research and offers distinct advantages over the mouse in transplantation models due to its size and close genetic similarity to humans. Sequencing of the rat genome and successful application of transgenic technologies which had only been available for mice have since led to a resurgence of the use of rat models. Transplantation provides the possibility to deliver transgenes through a variety of routes which can potentially offer treatment modalities for post-transplant dysfunction and rejection. Moreover, the use of genetically encoded fluorescent light probes has enabled in vivo visualization of organs and tissue in living animals. In recent years, generation of gene knockout rats via the zinc-finger nuclease (ZFN) and transcription activator-like effector nuclease (TALEN) technologies has offered alternatives to the sophisticated embryonic stem cell based gene-targeting. In this review, we aim to provide an overview of transplantation studies involving transgenic techniques using rat models and recent advances in methods to modify the rat genome. Through novel gene modification techniques, precise, complete and conditional knockout and knockin rat models have become available which can provide promising new treatment options and opportunities for studying human transplant-related pathophysiology.
