Illumina HumanHT-12 V3.0 expression beadchip
Description
The purpose of this study was to characterise the effects of trastuzumab and pertuzumab, either as single agents or as combination therapy on gene and protein expression in human ovarian cancer in vivo. Illumina BeadChips were used to profile the transcriptome after four days treatment of SKOV3 tumor xenografts. Although genes involved with HER2, MAP-kinase and p53 signaling pathways were commonly induced by all treatments, a greater number and variety of genes were differentially expressed by the complementary combination therapies compared to either drug on its own. The protein level of the CDK-inhibitors p21 and p27 were increased in response to both agents alone and further by the combination; pERK signaling was inhibited by all treatments; but only pertuzumab alone inhibited pAkt signaling. The expression of proliferation, apoptosis, cell division and cell cycle markers was distinct in a panel of primary ovarian cancer xenografts, suggesting heterogeneity of response in ovarian cancer and the need to establish biomarkers of response.

Description
In polygenic disorders we do not know exactly, how many genes are involved in the pathomechanism, but the analysis of fetal gene expression can get us closer to the solution. In our study we were searching for the genetic background of the polygenic neural tube defect, which is the second most common birth defect in the world (1 in 1000 live births). Our data revealed novel candidate genes, like SLAP, LST1 and BENE, which can play an important role in the pathogenesis of neural tube defects. We created a data warehouse from the results, suitable for further analysis. This study also demonstrates that a routinely collected amount of amniotic fluid (as small as 6 mL) is enough to successfully hybridize isolated RNA to expression arrays, making the ability to use the technique from normally collected amniotic fluid samples.
Publication Title
Use of routinely collected amniotic fluid for whole-genome expression analysis of polygenic disorders.

Description
In order to gain insights into how PPARg regulates different facets of dendritic cell (DC) differentiation, we sought to identify PPARg regulated genes and gene networks in monocyte-derived dendritic cells using global gene expression profiling. We employed an exogenous ligand activation approach using a selective PPARg ligand (rosiglitazone abbreviated as RSG). In addition, we have defined culture conditions in which human serum (HS) induces PPARg activation via a yet uncharacterized endogenous mechanism. We also compared the gene expression profile of developing dendritic cells obtained from patients harboring dominant negative mutations of the PPARg receptor (C114R and C131Y).
Publication Title
PPARgamma regulates the function of human dendritic cells primarily by altering lipid metabolism.

Illumina HiSeq 2000
Description
Purpose: RNA-Seq analysis can help identify large set of differentially expressed genes at a time. We performed RNA-Seq analysis to identify differentially expressed genes in the PBMCs of war veterans suffering from PTSD. Methods: Total RNA from PBMCs from PTSD +ve and -ve individuals were used for RNA-Seq analysis. Results: We obtained, on average, ~60 millions reads per sample. More than 70% of the reads were mapped to human genome. Functional analysis of the differentially expressed genes (362) revealed dysregulation in immune system network. Conclusions: Our present study provides further proof that immune system related genes and pathways are dysregulated in PTSD PBMCs. Overall design: RNA-Seq was performed with RNA from 5 each control and PTSD individuals. PBMCs collected within one hour of blood draw were used for RNA isolation. 1 ug of total RNA was used for library synthesis and sequenced in a HighSeq 2000 illumina instrument at Tufts University.

Description
CD14+ human monocytes differentiating into DCs in the presence of IL4 and GM-CSF were treated with agonists for RXR and its partners or vehicle 18 hours after plating (experiment with RXR and permissive partners, donor 1-3) or 14 hours after plating (experiment with nonpermissive partners, donor 4-6). Cells were harvested 12 hours thereafter. Experiments were performed in biological triplicates representing samples from three different donors.
