Gene expression in 832/13 INS1 beta-cells transduced with lentiviral vector conferring expression of GFP or Pax5

We found PAX5 to be overexpressed in human pancreatic islets of donors from donors with type 2 diabetes compared to islets from non-diabetic individuals. Functional follow-up showed that Pax5 overexpression in rat clonal beta-cells (832/13 INS1) results in impaired insulin secretion. Microarrays were used to investigate if overexpression of Pax5 alters the gene expression profile of 832/13 INS1 beta-cells. 16 samples, 8 from cells transduced with a control (GFP) virus and 8 transduced with a Pax5 virus. Cells were transdcued with a MOI of 1.25 and samples were collected 72h post transduction
