Submitter Supplied Information

Canonical IKK/NF-B signaling is a master regulator of inflammation and innate immunity and has been implicated in the pathogenesis of T1D. To investigate the impact of NF-B activation on -cell homeostasis and diabetes development, we generated a transgenic gain-of-function mouse model allowing conditional NF-B activation via expression of IKK2-CA (constitutively active IKK2 allele) in -cells using the tetracycline-regulated gene expression system. Pdx-1-tTA (knockin model generating Pdx-1 haploinsufficiency) driver mice were used for -cell specific transgene expression. Double transgenic IKK2-CA-pdx-1 mice develop a full-blown immune-mediated diabetes.To identify gene expression changes underlying this diabetes development pancreatic islets of diabetic IKK2-CA-Pdx-1, PDX-1 +/- and control mice were prepared and isolated total RNA was used for microarray analysis.
