Diabetes mellitus is a group of metabolic disorders characterized by hyperglycemia. The pathogenesis of these diseases involves β-cell dysfunction and death. The primary function of β-cells is to tightly regulate the secretion, production, and storage of insulin in response to blood glucose levels. In order to manage insulin biosynthesis, β-cells have an elaborate endoplasmic reticulum (ER).

The ER is an essential organelle for the proper processing and folding of proteins such as proinsulin. Proteins fold properly when the ER protein load balances with the ER folding capacity that handles this load. Disruption of this ER homeostasis by genetic and environmental ...
