But occasionally they do secrete an organic compound called porphyrin from a gland near the eye called the Harderian gland. Like NOD mice, biobreeding rats are used as an animal model for Type 1 diabetes. Many investigators who wish to trace observations on behavior and physiology to underlying genes regard aspects of these in rats as more relevant to humans and easier to observe than in mice, giving impetus to the development of genetic research techniques applicable to rat.
