From: Taurine regulates insulin release from pancreatic beta cell lines
Insulin immunoreactivity in Rin pancreatic insulinoma cell line. To test the efficacy of taurine in releasing insulin from the insulinoma cell line cultures were treated with no taurine (A-C) or 1 mM taurine (D-F) in increasing glucose concentrations. Cultures received either 0 mM glucose (A, D), the subthreshold concentration 1 mM glucose (B, E), or a concentration shown to initiate glucose release (3 mM; C, F). Cultures were immunostained for insulin (green). Blue structures are nuclei counterstained with DAPI.
