Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
Pheochromocytomas (PCC) are mostly benign tumors, amenable to complete surgical resection. However, 1017% of cases can become malignant, and once metastasized, there is no curative treatment for this disease. Given the need to identify effective therapeutic approaches for PCC, we evaluated the antitumor potential of the dual PI3K/mTOR inhibitor BEZ235 against these tumors. We employed an in vivo model of endogenous PCCs (MENX mutant rats), which closely recapitulate the human tumors. Mutant rats with PCCs were treated with 2 doses of BEZ235 (20 and 30 mg/kg), or with placebo, for 2 weeks. Treatment with BEZ235 induced cytostatic and cytotoxic effects on rat PCCs, which could be appreciated by both staining the tumors ex vivo with appropriate markers, and non-invasively by functional imaging (diffusion weighted-DW-MRI) in vivo.

Illumina HiSeq 2500
Description
ERG activity was blocked using YK-4-279 in three subcutaneously implanted ERG+ (LuCaP 23.1, 86.2, and 35) and one ERG- (LuCaP 96) PDX. Tumor volume (TV), body weight (BW), serum prostate specific antigen (PSA), and overall survival (OS) were compared to vehicle treated controls. Changes in gene expression were assessed by RNASeq and tissue microarrays were constructed to assess necrosis, proliferation, apoptosis, microvessel density, and ERG expression. Overall design: RNA sequencing of tumors from from 16 animals (2 control, 2 treated from each of four patient derived xenograft lines) using Illumina HiSeq 2500.

Description
The derivation of functional, transplantable HSCs from an pluripotent stem cells in vitro holds great promise for clinical therapies, but is unachieved. In order to achieve full functionality of HSCs, it is vital to determine the extent to which PSCs can currently be differentiated to the HSC program in vitro and identify the remaining dysregulated genetic pathways.

Description
RA signalling regulated endothelial to hematopoietic transition and HSC generation. Overall design: EB- or FL-derived HSPC were profiled before (d0) or after (d6) 6 days of treatment with 0.2uM AM580 on OP9, and after 6 additional days of expandion of OP9 (d12) without treatment.

Description
HOXA7 regulates FL-HSPC self-renewal in vitro and in vivo. We profiled EB-HSPCs after HOXA7 overexpression (EB-HOXA7), or with a control vector (EB-CTR), to assess the gene expression programs regulated by HOXA7. Overall design: CD34+CD38-CD43+CD90+ HSPCs were infected with lentiviral FUGW vector either empty (FUGW-GFP) or encoding HOXA7(FUGW-GFP-HOXA7) protein. Cells were expanded on op9 for 15 days and than sorted for GFP HSPC immunophenotype.

Description
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.
