The purpose of the experiment was to generate a time course of gene expression following irradiation. The goal was then to model this data to extract hidden variables - chiefly, the activity profiles of the p53 transcription factor. Using this information the aim was to predict which transcripts changed by IR were targets of p53. Cells in log phase (1 x 106 ml-1) were ?-irradiated with 5 Gy at room temperature (RT) at a dose rate of 2.45 Gy per minute with a 137Cs ?-irradiator. Cells were harvested at 0, 2, 4, 6, 8, 10 and 12 hours, and RNA and protein were extracted (Trizol, Invitrogen). Affymetrix U133A arrays were hybridized as standard (www.affymetrix.co.uk). Array quality was determined using R and GCOS .rpt file values. The time course was replicated three times from independent cell preparations.

View SamplesDespite Hedgehogs influence on T-cell activation and proliferation, the transcriptional targets of Gli2 in lymphocytes are not known. We therefore examined the Hedgehog-dependent transcriptional response of resting and early-stage activated T-cells in order to define their transcriptional response to Hedgehog pathway activation.

View SamplesThe basic design of the experiment is as described in Fryer et al.(2000)Diabetes 49:1978, and is similar to proto-BAIR (EXP_BAIR_0603_02). H-2Kb muscle cells were treated with metformin (2mM) or insulin (100nM) for 0, 2 or 12 hours.
