Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Generation of human fibroblast-derived hepatocytes capable of extensive proliferation, as evidenced by significant liver repopulation of mice. Unlike current protocols for deriving hepatocytes from human fibroblasts, ours did not generate iPSCs, but shortcut reprogramming to pluripotency to generate an induced multipotent progenitor cell (iMPC) stage from which endoderm progenitor cells (iMPC-EPCs) and subsequently hepatocytes (iMPC-Heps) could be efficiently differentiated. After transplantation into an immune-deficient mouse model of human liver failure, iMPC-Heps were able to engraft and proliferate, and acquired levels of hepatocyte function similar to adult hepatocytes.

- Affymetrix Pseudomonas aeruginosa Array (paeg1a)
Description
Pseudomonas aeruginosa (P. aeruginosa) lung infection is a significant cause of mortality in patients with cystic fibrosis (CF). Existing experimental data in our lab showed significantly different levels of virulence of "early" and "late" P. aeruginosa infection isolates in a C. elegans slow killing model. We wished to examine the expression profile of these isolates in order to explore genes that may be responsible for the observed differences. The expression profiles of two pairs of isolates (four isolates in total) were compared to each other using the Affymetrix P. aeruginosa PAO1 genome array, to gain insight into properties mediating virulence in these isolates. Data analysis was carried out using BIOCONDUCTOR software.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Plant drought stress response and resistance are complex biological processes that merit systems-level analyses to dissect drought stress encountered by crops in the field. We have used gene expression profiling of Arabidopsis plants subjected to a controlled, sublethal, moderate drought (mDr) treatment to characterize early and late response to drought. We have also compared these profiles to those from plants treated with soil water deficit (progressive) drought (pDr) to reveal acclimation responses in plants.
Publication Title
Molecular and physiological analysis of drought stress in Arabidopsis reveals early responses leading to acclimation in plant growth.

Description
In order to understand the effect of genetic background on the response to gene dose perturbation, we performed mRNA transcriptional profiling on 99 hemizygotic lines (Df/+) from the DrosDel project, which have hybrid genetic background of OregonR/w1118. Overall design: We performed RNA-Seq analysis of 417 single adult flies in duplicate or triplicate. Flies are from 73 different genotypes. Differential gene expression was analyzed separately for each sex, gene expression from each genotype was compared to normalized mean of gene expression remaining 72 genotypes.

Description
We performed mRNA transcriptional profiling on 99 hemizygotic lines (Df/+) from the DrosDel project covering 68% of chromosome 2L, in order to understand how changes in gene copy number affect overall transcriptome. Overall design: We performed RNA-Seq analysis on 396 pools of 15-25 adult flies each. Samples include males or females from 99 different genotypes in duplicate. Differential gene expression was analyzed separately for each sex, by comparing each genotype with the remaining 98.

Description
To measure the response to gene dose, we performed mRNA-Seq of fly heads with molecularly defined deletions constructed from DrosDel deficiency lines (Ryder et al. Genetics 2007, 177(1):615-29) on the Illumina HiSeq 2000 platform. Overall design: We performed single-end next-generation sequencing (RNA-Seq) on poly-A+ RNA extracted from adult female and male heads in biological triplicate. Besides wildtype females (XX) and males (XY) that were heterozygous for deletions, we also sequenced females that were transformed into males (XX males) by using mutations in the sex determination gene transformer-2 (tra2). The original lines with deletions, including 22 deletions on the chromosome X and 12 deletions on the chromosome 3L, were from the DrosDel project. The diploid controls without DrosDel deletions were derived from w1118 (the parental line of DrosDel stocks) or Oregon-R Strain. We sequenced a total of 249 samples.

Description
We have used microarrays to comprehensively describe the transcriptomes of the supraoptic nucleus (SON), the paraventricular nucleus (PVN) and the neurointermediate lobe (NIL) of adult male Sprague-Dawley (SD) and Wistar-Kyoto (WKY) rats, as well as the paraventricular nucleus of Wistar (WIST) rats. Comparison of these gene lists has enabled us to identify surprisingly large differences in hypothalamo-neurohypophyseal system gene expression patterns in these three strains. We have also shown that different transcript populations are enriched in the PVN and the SON of SD and WKY rats. The transcriptome differences catalogued here may be molecular substrates for the neuro-humoral phenotypic differences exhibited by different strains of rats.
