Affymetrix Human Genome U95A Array (hgu95a)
Description
We used high density oligonucleotide arrays to identify molecular correlates of genetically and clinically distinct subgroups of B-cell chronic lymphocytic leukemia (B-CLL). Gene expression profiling was used to profile the five most frequent genomic aberrations, namely deletions affecting chromosome bands 13q14, 11q22-q23, 17p13 and 6q21, and gains of genomic material affecting chromosome band 12q13. A strikingly high degree of correlation between loss or gain of genomic material and the amount of transcripts from the affected regions leads to the hypothesis of gene dosage as a significant pathogenic factor. Furthermore, the influence of the immunoglobulin variable heavy chain (VH) mutation status was determined. A clear distinction in the expression profiles of unmutated and mutated VH samples exists, which can be discovered using unsupervised learning methods. However, when samples were separated by gender, this separation could only be detected in samples from male patients.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Men are at an increased risk of dying from heart failure caused by inflammatory heart diseases such as atherosclerosis, myocarditis and dilated cardiomyopathy (DCM). We previously showed that immune responses in the heart are phenotypically distinct in male compared to female mice 10 days after infection resulting in severe DCM in males.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
We hypothesize that gene expression in the lungs of these differentially-treated mice are divergent thus contributing to the disparity in their phenotypes. More specifically, (1) Effects of Leptin-treatment of ob/ob postnatal mice lungs are known to be volume-dependent from 2 to 10 wks of age, and are independent of the hypometabolism associated with leptin deficiency. ; (2) Leptin is critical to postnatal lung remodeling, particularly related to enlarged alveolar surface area. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between lungs of leptin or saline-treated ob/ob postnatal mice.

Illumina HiSeq 2000
Description
Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived brain transcriptome profiling (RNA-seq) in neuropathic region specific Gaucher mouse brain compared with WT and Isofagamine treated mice of the same age and background and secondly to identify the DEmiRNA associated with the DEmRNA before and after treatment This will give us some insights to see if miRNA is also involved in the the regulation of the expression of the genes involved in the disease process before and after treatment. Methods: 42-45 days old 4L;C*, wild-type (WT) and Isofagamine treated 4L;C* mouse brain were generated by deep sequencing, in triplicate, using IlluminaHiseq. The sequence reads that passed quality filters were analyzed at the gene level with two methods: Burrows–Wheeler Aligner (BWA) followed and TopHat followed by DESeq. qRT–PCR validation was performed using TaqMan and SYBR Green assays Overall design: Regional brain mRNA profiles of ~42 -days old wild type (WT) and 4L;C* an d Isofagamine treated mice were generated by deep sequencing, in triplicate, using IlluminaHi Seq.
