The pineal hormone melatonin influences the secretion of insulin by pancreatic islets via the G‑protein‑coupled melatonin receptors 1 and 2 that are expressed in pancreatic β‑cells. Genome‑wide association studies indicate that melatonin receptor 1B (MTNR1B) single nucleotide polymorphisms are tightly associated with type 2 diabetes mellitus (T2DM). However, the underlying mechanism is unclear. Raf‑1 serves a critical role in the mitogen‑activated protein kinase (MAPK) pathways in β‑cell survival and proliferation and, therefore, may be involved in the mechanism by which melatonin impacts on T2DM through MTNR1B...

Alternative cell models of human neural stem cells (hNSCs) have been developed and used for investigations ranging from in vitro experiments to in vivo clinical studies. However, a cell model capable of mimicking the 'normal' state of hNSCs is mandatory in order to extrapolate the results of these studies to humans. In the present study, to select a more suitable hNSC model for developing human‑based experimental platforms, two representative hNSC types were compared, namely human embryonic stem cell (hESC)‑derived hNSCs and ReNcell CX cells, which are well‑characterized immortalized hNSC lines...
