Description
Colorectal carcinoma is the third leading cause of cancer-related death in the United States. In order to understand the mechanism/signaling pathways responsible for invasion, migration and metastasis in colorectal cancer, we developed an integrative and comparative genetic approach to infer transcriptional regulatory mechanisms underlying colon cancer progression. Accordingly, we filtered fourteen human colorectal cancer (CRC) microarray data sets, from an immune competent mouse model of metastasis to identify known and novel transcriptional regulators in CRC. Using this approach, Nuclear Factor of Activated T cells (NFAT) family of transcription factors were identified as metastasis driver of colon cancer. NFAT family of transcription factors is known to induce gene transcription in various disease processes, including carcinogenesis. We used parental and metastatic derivatives of MC38 mouse colon cancer cells (MC38Par and MC38Met, respectively) to evaluate the role of NFATc1 in cancer cell invasiveness. We found that high NFATc1 expression correlates with significantly increased (p<0.0001) Trans-Endothelial Invasion (TEI) in MC38Met cells. Conversely, RNAi-based inhibition of NFATc1 expression and functional inhibition with calcineurin inhibitor FK506 in MC38Met cells, both resulted in significant decreased TEI (p=0.0193 & p=0.0003). Furthermore, a set of predicted NFATc1 target mRNAs identified in our original analysis were downregulated by knock-down of NFATc1 or functional inhibition with FK506 in MC38Met cells. The expression level (mRNA) of predicted gene targets were high in human CRC specimens which had higher than median NFATc1 mRNA expression (n=11 out of total 22). The tumor-associated NFATc1 co-regulated gene signature is significantly correlated with both disease-specific and disease-free survival in Stage II and III CRC patients. We have successfully demonstrated a bioinformatics approach to identify a tumor promoter driver gene NFATc1. Our studies suggest a role of NFATc1 towards invasion and its co-regulated gene signature for poor outcomes in colorectal cancer.

Description
The entorhinal cortex of the mouse seems to be sensitive to molecular mechanisms that have been linked to the pathology of Alzheimer's disease. In this microarray study we are interested in comparing the expression profile of the left versus the right EC of the mouse, in order to understand if there is a significant difference in gene expression that might reveal any insights into the differential activation of these areas.

Description
We report an applicaton of small RNA sequencing using high throughput next generation sequencing to identify the small RNA content of cell lines. By sequencing over 30 million reads we could identify a new class of small RNAs previousy observed with tiling arrays and mapping to promoter regions of coding genes. We also identified a large number of small RNAs corresponding to internal exons of coding genes. By using different enzymatic treatments and immunoprecipitation experiments, we have determined that both the promoter associated small RNAs as well as ones within the body of the genes bear 5'' cap structures. Overall design: Examination of the expression of small RNAs (<200nt).

Description
We report that the HF/HS-mediated functional enrichment of genes of immunity and inflammation is driven toward normal by the AOF supplementation Obesity may not constantly associate with metabolic disorders and mortality later in life, raising the challenging concept of healthy obesity. Here, high fat-high sucrose (HF/HS) feeding produces hyperglycaemia and hypercholesterolemia, increases oxidative stress, elevates endotoxemia, expands adipose tissue (with enlarged adipocytes, macrophage infiltration and accumulation of cholesterol and oxysterols), and reduces lifespan of obese mice. Despite persistence of obesity, supplementation with an antioxidant formulation normalizes plasma lipids and endotoxemia, prevents macrophage recruitment in adipose tissue, reduces adipose accumulation of cholesterol and cholesterol oxides, and extends lifespan. The HF/HS-mediated functional enrichment of genes of immunity and inflammation (in particular response to lipopolysaccharides) is driven towards normal by the antioxidant formulation. It is concluded that the limitation of immune cell infiltration in adipose tissue on the long term by an antioxidant formulation can increase lifespan independently of body weight and fat storage. It constitutes the hallmark of a healthy adiposity trait. Overall design: Examination of the expression profile of mice adipose tissues fed either standard (Std), High-fat/high-sucrose (HF/HS) or HF/HS + antioxidant formulation (AOF) for 180 days

Description
Human pluripotent stem cell-based in vitro models that reflect human physiology have the potential to reduce the number of drug failures in clinical trials, and offer a cost effective approach for assessing chemical safety. Here, human embryonic stem (ES) cell-derived neural progenitor cells, endothelial cells, mesenchymal stem cells, and microglia/macrophage precursors were combined on chemically-defined poly(ethylene glycol) (PEG) hydrogels and cultured in serum-free media to model cellular interactions of the developing brain. The precursors self-assembled into 3-dimensional (3D) neural constructs with cortically organized neuronal and glial cells, interconnected vascular networks, and ramified microglia. Replicate constructs were highly reproducible by RNA sequencing (Spearman's correlation coefficients, ? = 0.97) and robustly expressed neurogenesis, vasculature development, and microglia genes. Finally, linear support vector machines were used to construct a predictive model from RNA sequencing data for 240 neural constructs treated with 60 toxic and non-toxic chemicals, which then correctly classified 9/10 blinded compounds. Overall design: Note that all cell types were derived from the H1 human embryonic stem cell line. 11 samples for initial quality control (triplicate day 13 neural progenitor cells; quadruplicate day 21 neural progenitor cells cocultured with mesenchymal stem cells and endothelial cells; quadruplicate day 21 neural progenitor cells cocultured with mesenchymal stem cells and endothelial cells and migroglia/macrophage precursor cells), quadruplicate samples of H1 ES cells as a control for comparing to untreated toxicity study samples, and 288 samples associated with toxicity screening (all samples formed using neural progenitor cells, endothelial cells, mesenchymal stem cells, and microglia/macrophage precursors).
