ER stress

Over the last few years we have developed an increasing interest in the role of endoplasmic reticulum (ER) stress in various conditions and especially in metabolic diseases. We are especially interested in understanding how variations in ER stress and the resulting unfolded protein response (UPR) interferes with the adaptation of individuals at different environments and the onset and progression of ER stress-associated pathologies. For our studies we use outbred deer mice (Peromyscus) as a model. These small mammals, although similar to mice possess unique sets of features that render them ideal for the study of stress biology in the context of genetically diverse populations.
