Aim of the experiment is the identification of genes regulated by PI3K-dependent signaling in undifferentiated ES cells. Materials and methods: To identify target genes of PI3-K signalling, the PI3-K signalling inhibitor LY294002 was used at a concentration which was shown to perturb self-renewal in the presence of LIF and which knocks down PI3K signals. CGR8 cells cultivated in serum-free conditions in the presence of LIF were starved for 24h in media lacking LIF and then pre-inubated for 30 minutes with 5 mM LY294002 in DMSO or with DMSO alone. Cells were then stimulated with LIF for 2h, prior to preparation of RNA samples. Relationships between samples: Samples were either maintained in LIF or LIF plus LY294002 (PI3K inhibitor) for the required treatment times. Treatments: Treatment times with PI3K inhibitor LY294002 at 5 uM 2h (n=5), 3h (n=5).']</item><item key="source">http://www.ebi.ac.uk/arrayexpress/experiments/E-TABM-673</item><item key="sample_source">http://www.ebi.ac.uk/arrayexpress/experiments/E-TABM-673/samples/</item></data></biogps>
