Description
Currently there is a lack of effective therapies which result in long-term durable response for patients presenting with advanced and metastatic clear cell renal cell carcinoma (ccRCC). This is due in part to a lack of molecular factors which can be targeted pharmacologically. In order to identify novel tumor-specific targets, we performed high throughput gene array analysis screening numerous patient ccRCC tumor tissues across all stages of disease, and compared their gene expression levels to matched normal kidney. Our results identify a number of genes which demonstrate tumor-specific overexpression, and may present as novel targets for therapy.

Description
We individually examined the ability of human ARGFX, DPRX, LEUTX, and TPRX1 to regulate gene expression by ectopically expressing these proteins in fibroblasts. Overall design: Each gene along with an empty control vector were transfected individually to drive ectopic expression in human dermal fibroblasts, in triplicate.

Description
Currently there is a lack of effective therapies which result in long-term durable response for patients presenting with anaplastic thyroid carcinoma (ATC), a very rare and lethal variant of thyroid cancer. ATC is resistant to chemotherapy, radiation, and targeted therapies currently available. In an effort to identify novel tumor-specific therapeutic targets, we performed high throughput gene array analysis screening numerous patient ATC tumor tissues, and compared their gene expression levels to matched and unmatched normal thyroid tissue samples.

Description
Presently, there is a deficiency of effective therapies designed to target clear cell renal cell carcinoma (ccRCC), with poor prognosis resulting in patients with advanced disease. Additionally, there is a lack of molecular factors which can be remedially targeted resulting in tumor specific inhibition, and therefore current therapeutic approaches often produce adverse side effects in patients. We identified that Stearoyl-CoA desaturase 1 (SCD1) was consistently overexpressed in patient ccRCC samples, and further investigation of SCD1 as a potential molecular target for ccRCC intervention utilizing a SCD1 inhibitor (A939572) resulted in tumor specific growth inhibition and induction of cell death. In order to understand the mechanism by which the SCD1 inhibitor mediated its anti-tumor effects, we performed gene array analysis and compared expression patterns between treated and untreated samples.

Description
The aim of this experiment was to investigate differential gene expression in splenocytes stimulated with BCG from nave and BCG vaccinated mice. The differences between nave and BCG vaccinated mice might indicate the mechanisms by which BCG vaccination confers an enhanced ability of splenocytes from BCG vaccinated mice to inhibit growth of BCG in splenocyte cultures as compared with splenocytes from naive animals.

Description
Defective insulin secretion by pancreatic ß cells underlies the development of type 2 diabetes (T2D). High fat diet-fed mice are commonly used to study diabetes progression, but studies are usually limited to a single strain, such as C57Bl/6J. Here, we use a systems biology approach to integrate large phenotypic and islet transcriptomic data sets from six commonly used strains fed a high fat or regular chow diet to identify genes associated with glucose intolerance and insulin secretion. One of these genes is Elovl2, encoding very long chain fatty acid elongase 2. ELOVL2 is responsible for the synthesis of the polyunsaturated fatty acid, docosahexaenoic acid (DHA). We show that DHA rescues glucose-induced insulin secretion and cytosolic Ca2+ influx impaired by glucolipotoxicity, and that Elovl2 over-expression is able to restore the insulin secretion defect under these conditions. We propose that increased endogenous DHA levels resulting from Elovl2 up-regulation counteracts the insulin secretion defect associated with glucolipotoxicity. Although we focus our experimental validation on Elovl2, the comprehensive data set and integrative network model we used to identify this candidate gene represents an important novel resource to dissect the molecular aetiology of ß cell failure in murine models. Overall design: 6 mouse strains, 4 time points, 2 diets

Transient expression of two factors, or from Oct4 alone, resulted in efficient generation of human iPSCs. The reprogramming strategy described revealed a potential transcriptional signature for human iPSCs yet retaining the gene expression of donor cells in human reprogrammed cells free of viral and transgene interference.

Description
Human medulloblastoma (MB) can be segregated into four major categories based on gene expression patterns: Hedgehog (HH) subtype, Wnt subtype, Group 3, and Group 4. However, they all exhibit strikingly different gene expression profiles from Atypical Teratoid/Rhabdoid Tumor (AT/RT). We re-analyzed published gene expression microarray dataset of pediatric brain tumors to identify a gene expression profile that clearly distinguished human AT/RT from human MB. We used this profile, choosing only genes that have clear murine orthologs, to compare tumors from Snf5F/Fp53L/LGFAP-Cre mice (in C57Bl/6 strain background) with MB from Ptc1+/- mice (in mixed C57Bl/6 and 129Sv strain background). Snf5F/Fp53L/LGFAP-Cre tumors are clearly very different from mouse MB and the markers that distinguish human AT/RT from human MB also distinguish the mouse tumors.
