Failure of glucose and IL-1β to induce iNOS mRNA expression in human islets. RT-PCR analysis of iNOS expression by islets cultured for 44 hours in 5.5 and 33.3 mM glucose or with IL-1β alone or in combination with IFN-γ (positive control). GAPDH was used as control. One of three experiments from three donors is shown.
