Functional abnormalities in isolated arteries from Goto-Kakizaki and streptozotocin-treated diabetic rat models.
Several different rat models have been developed for both type 1 and type 2 diabetes with the aim of displaying specific traits of diabetes. For example, a review on nephropathy associated with type 2 diabetes included 16 different rodent models ; new models are still being developed. The large number of different models developed for different traits makes it difficult to choose the right model for a given study. It is often a problem that the models are not sufficiently characterized, which makes it easy to misinterpret data or even come to the wrong conclusions. In this brief review, we will concentrate on the functional responses obtained in vitro from mesenteric arteries and aortic segments from rat models of diabetes. Since it is beyond the scope of this review to overview all different rodent models of diabetes, we will focus on two commonly used models of diabetes, namely the streptozotocin (STZ)-induced type 1 diabetic rat model and the inbred type 2 diabetic Goto-Kakizaki (GK)-rat model.
