GFP BM cells were collected 24 hours after injection, and surface marker Immunoblotting. Membranes were probed together with the following antibod- profiles were analyzed. ies: anti-IB (Cell Signaling Technology), anti hospho-IB (Ser32) Evaluation of microarray data. We analyzed publicly offered gene expres(Cell Signaling Technologies), anti-p65 (Santa Cruz Biotechnology Inc.), sion microarray information on murine and human samples in the Gene anti hospho-p65 (Ser536) (Cell Signaling Technologies), antiactin Expression Omnibus (GEO) database (GEO GSE24797, GSE20377, and (Cell Signaling Technology), and anti istone H3 (Cell Signaling Tech- GSE24006). A set of CEL files had been downloaded from GEO and normalnology). Protein levels had been quantified with ImageJ computer software (NIH). To ized applying the JustRMA function in the Affy package 1.22.1 in Bioobtain nuclear and cytoplasmic extracts, an Active Motif Nuclear Extract conductor. To evaluate expression profiles with the NF-B target genes, Kit was used in accordance with the manufacturer’s guidelines. Cycloheximide normalized information had been tested for GSEA using previously described NF-B treatment assay was performed as described previously, with modification target gene sets (29), along with a nominal P value was calculated. For screening (52). Cells had been pretreated with MG132 (20 M) for 1 hour to initially of genes with elevated expression levels in LICs compared with those in inhibit the proteasomal degradation of IB. Cells have been washed twice normal HSPCs, the expression values of person genes have been compared with medium, then cultured with or without the need of 10 gml of cycloheximide in between groups.
