(Submitter supplied) Somatic rearrangements of transcription factors are common abnormalities in the acute leukemias. With rare exception, however, the resultant protein products have remained largely intractable as pharmacologic targets. One example is AML1-ETO, the most common translocation reported in acute myeloid leukemia (AML). To identify AML1-ETO modulators, we screened a small molecule library using a chemical genomic approach. more...

(Submitter supplied) The identification of genes that contribute to the biological basis for clinical heterogeneity and progression of prostate cancer is critical to accurate classification and appropriate therapy. We performed a comprehensive gene expression analysis of prostate cancer using oligonucleotide arrays with 63,175 probe sets to identify genes and expressed sequences with strong and uniform differential expression between nonrecurrent primary prostate cancers and metastatic prostate cancers. more...

(Submitter supplied) The incidence of prostate cancer is frequent, occurring in almost one-third of men older than 45 years. Only a fraction of the cases reach the stages displaying clinical significance. Despite the advances in our understanding of prostate carcinogenesis and disease progression, our knowledge of this disease is still fragmented. Identification of the genes and patterns of gene expression will provide a more cohesive picture of prostate cancer biology. more...

(Submitter supplied) FCHL is a common, complex genetic lipid disorder with a largely unknown aetiology. Altered adipose tissue metabolism has been implicated as contributing to FCHL. We used microarrays to investigate the mRNA profiles of FCHL patients with CHD and non-FCHL patients with CHD in comparison with non-FCHL, non-CHD patients to define a core set of genes that were differentially expressed in FCHL and to provide a reasonable launch-pad for examining the direct contribution of one of this gene set to the development of adipose tissue.

(Submitter supplied) Surgical samples have long been used as important subjects for cancer research. In accordance with an increase of neoadjuvant therapy, biopsy samples have recently become imperative for cancer transcriptome. On the other hand, both biopsy and surgical samples are available for expression profiling for predicting clinical outcome by adjuvant therapy; however, it is still unclear whether surgical sample expression profiles are useful for the prediction by the use of biopsy samples because little has been done about comparative gene expression profiling between the two kinds of samples. more...

(Submitter supplied) The gene coding for RNA binding motif protein 35A (RBM35A) is inactivated by frameshift mutations in an LS180 colon carcinoma cell line and in approximately in 50% of colon tumors with microsatellite instability. To get insight into the mechanism of action of these putative tumor suppressor gene we expressed functional copy of the RBM35A cDNA in the LS180 cells. We analyzed alterations in mRNA profiles in total and in polysomal fraction of mRNA in LS180 cells in response to expressing RBM35A gene under Tet off tetracycline inducible promoter. more...

(Submitter supplied) Gain-of-function mutations in exon 3 of beta-catenin (CTNNB1) are specific for Wilms' tumors that have lost WT1, but 50% of WT1-mutant cases lack such "hot spot" mutations. To ask whether stabilization of beta-catenin might be essential after WT1 loss, and to identify downstream target genes, we compared expression profiles in WT1-mutant versus WT1 wild-type Wilms' tumors. Supervised and nonsupervised hierarchical clustering of the expression data separated these two classes of Wilms' tumor. more...

(Submitter supplied) The aim of the project was to explore the feasibility of gene expression profiles as a general diagnostic tool. Therefore the most frequently used and easy to use white blood cells have been profiled. We wanted to examinate, whether phenotypes created by organs different from blood cells have enough influence on these cells to allow the diagnosis of their presence. As a proof of principle we tried to identify surrogate markers for human sex (excluding markers on sex chromosomes). more...
