Transcription profiling of rat insulinoma-beta (INS-1E) cells exposed to the cytokines IL-1-beta and IFN-gamma for six different lengths of time and with or without the inducible NO synthase blocker NMA

ABSTRACT: Locally released cytokines contribute to beta cell dysfunction and apoptosis in Type 1 diabetes. In vitro exposure of insulin producing INS-1E cells to the cytokines interleukin (IL)-1beta + interferon (IFN) gamma leads to a significant increase in apoptosis. To characterize the genetic networks implicated in beta cell dysfunction and apoptosis and its dependence on nitric oxide (NO) production, we performed a time course analysis using the Affymetrix RG U34A microarry. INS-1E cells were exposed in duplicate to IL-1beta + IFN-gamma for six different time points (1, 2, 4, 8, 12, and 24 h) with or without the inducible NO synthase blocker.
