Project description:This SuperSeries is composed of the following subset Series:; GSE1589: Targets of HNF1b, HNF4a2 and HNF6 in INS-1 cells; GSE1590: Targets of HNF1b mutants in INS-1; GSE1591: INS-1 cell lines (FLP-In T-REx) Experiment Overall Design: Refer to individual Series
Project description:Identification of genes regulated by the transcription factor HNF4a2 Experiment Overall Design: We used microarrays to identify genes regulated by the transcription factor HNF4a2. HEK293 cell lines containing doxycyclin-inducible wilt type or mutant forms of HNF4a2m which were introduced by FRT/FLP mediated recombination into FLP-In T-REx 293 cells (Invitrogen) were treated for 24 hours with 1 µg/ml doxycyclin. Gene expression profiles of induced and noninduced cells were compared to identify HNF4 regulated targets.
Project description:Four rat insulinoma cell lines (INS-1) were generated that contain a FRT site for FLP recombinase mediated site specific integration of specific genes. In addition, the cell lines contain the tetracycline repressor allowing tetracycline (tet) induction of the introduced gene. By comparing the gene expression profiles of uninduced and tet-induced cells, target genes of introduced transcription factors or other signal tranduction molecules can be identified. The expression profiles of the parental INS-1 cell line and the four derivatives were determined on a RAE230A array, showing that the highly differentiated phenotype of the parental cell line was maintained in the clones.
