Affymetrix Human Genome U133A Array (hgu133a)
Description
Baseline glucocorticoid resistance profiles were measured in a panel of 15 paediatric T-Cell acute lymphoblastic leukaemia cell lines and correlated with Affymetrix Gene expression to identify genes and pathways associated with drug resistance in T-ALL. The cell lines' resistance to Methylprednisolone (MPRED) and Dexamethasone (DEX) was then tested using the MTT assay and IC50 values (drug concentration lethal to 50% of cells) for each drug were calculated.

Description
Severe asthma exacerbations in children requiring hospitalisation are typically associated with viral infection, and occur almost exclusively amongst atopics, but the significance of these comorbidities is unknown. We hypothesised that underlying interactions between immunoinflammatory pathways related to responses to aeroallergen and virus are involved, and that evidence of these interactions is detectable in circulating cells during exacerbations.

Interactions between innate antiviral and atopic immunoinflammatory pathways precipitate and sustain asthma exacerbations in children.

Description
Dendritic cells differentiate from their precursors in the airway mucosa under local environmental instruction. Airway epithelial cells (AEC) are a potent source of both pro- and anti-inflammatory mediators and are in intimate contact with intraepithelial DC and their precursors. Thus, AEC are likely candidates for influencing this differentiation process in order to tailor the DC for optimal function in the airway mucosa.

Description
B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is a heterogeneous disease that can be subdivided according to primary recurrent genetic abnormalities that are strongly associated with characteristic biological and clinical features. The detection of these abnormalities can facilitate diagnosis, risk stratification, and targeted therapy.

Description
We have examined the biological effect of EWS/ETS in human MPCs using UET-13 cells that are obtained by prolonging the lifespan of human bone marrow stromal cells using the retroviral transgenes hTERT and E7. By exploiting tetracycline-inducible systems for expressing EWS/ETS (EWS/FLI1 and EWS/ERG), we investigated candidates for genes whose expression is regulated by EWS/ETS in human MPCs.

Description
For identification of candidate genes that is specifically expressed in Ewing family tumor (EFT) cells, we performed DNA microarray-based global expression profiling using Affymetrix Human Genome U133 Plus 2.0 Array and analyxed expression profiles from EFT cell lines (7 lines), neuroblastoma (NB) cell lines (3 lines), a Rhabdomyosarcoma (RMS) cell line, and a human immortalized mesenchymal progenitor cells UET-13 cells.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
To predict Rp58-regulated gene involved in myogenesis, RNA profiling experiments were performed, comparing RNA derived from C2C12 with or without expressing shRNA for Rp58. As a result, 271 genes were upregulated in C2C12 stably expressing shRNA-Rp58 cells compared with control C2C12 cells. As Rp58 is repressor in C2C12, we hypothesized that Rp58 regulates gene cluster which expression is downregulated in accordance with Rp58 expression and myogenesis progression. In this regard, we also characterized dynamic gene expression patterns during myogenesis by microarray at 4 different stage (GM, day 0, 2, 4) of C2C12 myogenesis assays and found that 399 genes expression is characterized as downregulation pattern during myogenesis. Importantly, this down regulation gene set and upregulated genes by shRNA for Rp58 were highly overlapped.

Description
To predict RP58-regulated genes involved in skeletal myogenesis, RNA profiling experiments were performed, comparing RNA derived from skeletal muscle tissue of a RP58+/+ mouse to that from a RP58 knockout (KO) mouse at E18.5. Importantly, well-known dominant-negative inhibitors of muscle differentiation, the Id family of genes (Id1/Id2/Id3), were upregulated in the RP58 KO muscle. On the contrary, a number of muscle differentiation-related genes, such as Ckm, troponin and Myosin, were downregulated in the same sample. These results indicate that the repressor protein RP58 is important for muscle terminal differentiation, possibly suppressing the gene expression of muscle differentiation genes such as the Ids.
