The β-cell of the pancreatic islets is constituted of a network of calcium signaling pathways strongly involved in insulin biosynthesis and insulin release. The pineal hormone melatonin influences the insulin secretion and the gene expression of components of the calcium/calmodulin-signaling pathwaysparticipating in the regulation of insulin secretion. Furthermore, the crucial impact of melatonin receptor density and melatonin receptor loss on transcript level regulation is shown. In pancreatic

The results of the present study contribute to a better understanding of a complex melatonin impact on β-cells including their signaling pathways. Perspectively, the results of the present study provide new approaches for the therapy of type 2 diabetes mellitus.
