Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Deregulation of translational control is an obligatory step in oncogenesis; however, this step has not been addressed by prior genomic and transcriptional profiling studies of cancer biology. Here we simulate the translational deregulation found in cancer by ectopically over expressing translation initiation factor eIF4E in primary human mammary epithelial cells; and examine its impact on cell biology and the pattern of ribosomal recruitment to mRNA genome wide. Over expression of eIF4E allows cells to bypass M0 premature growth arrest, but does not confer other malignant properties. However, in concert with hTERT, eIF4E imparts cells with growth and survival autonomy - and profoundly alters the pattern of polyribosome-associated mRNA encoding cell cycle and apoptosis regulators. The translational response to increased eIF4E is not only a unidirectional activation of oncogenic drivers, but also consists of complex intrinsic translational mechanisms that mitigate the acquisition of neoplastic properties.
Publication Title
Eukaryotic translation initiation factor 4E induced progression of primary human mammary epithelial cells along the cancer pathway is associated with targeted translational deregulation of oncogenic drivers and inhibitors.

Affymetrix Human Gene 2.0 ST Array (hugene20st), Illumina Genome Analyzer II
Description
We report that full length TET1 (TET1-FL) overexpression fails to induce global DNA demethylation in HEK293T cells. The preferential binding of TET1-FL to hypomethylated CpG islands (CGIs) through its CXXC domain leads to its inhibited 5-hydroxymethylcytosine (5hmC) production as methylation level increases. TET1-FL-induced 5hmC accumulates at CGI edges, while TET1 knockdown induces methylation spreading from methylated edges into hypomethylated CGIs. However, TET1 can regulate gene transcription independent of its dioxygenase catalytic function. Thus, our results identify TET1 as a maintenance DNA demethylase that does not purposely decrease methylation levels, but specifically maintains the DNA hypomethylation state of CGIs in adult cells.

Description
RNA-seq was performed after MCF7 cells were treated with S2101, UNC0638, GSK343, depsipeptide alone or in combination with decitabine Overall design: Biological triplicates were performed for a total of 30 samples. Fold change of each gene was calculated by comparing change in expression after inhibitor treatment to expression in the control samples

Description
Purpose: To identify transcriptional changes by RNA-seq in tumor samples, before bevacizumab combination treatment and after bevacizumab combination treatment in both responding and non-responding recurrent glioblastoma patients Overall design: Three comparison analyses were further performed: 1.) Paired analysis of pre- and post-treated samples from responding patients; 2.) Comparison of pre-treated samples of responders vs. non-responders; 3.) Paired analysis of pre- and post-treated samples from non-responding patients The sample ''characteristics: batch'' represents a combination of the RNA-extraction date and the library-preparation date for each sample.
