Illumina HiSeq 2500
Description
Surfactant deficiency, diffuse alveolar damage and respiratory failure caused by loss of Abca3 in AT2 cells was followed by remarkable proliferation of alveolar cells and selective survival of ABCA3 sufficient cells resulting in regeneration of alveolar structure and function, providing the conceptual framework for the development of therapies to ameliorate lung diseases caused by mutations in ABCA3 and other genes critical for AT2 cell function or surfactant homeostasis. Overall design: Control and Abca3 cKO AT2 cell RNA-seq at 6 days post tamoxifen in adult mice.
Publication Title

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
ARC (NSC 188491, SMA-491), 4-amino-6-hydrazino-7-beta-d-ribofuranosyl-7H-pyrrolo-(2,3-d)-pyrimidine-5-carboxamide, is a nucleoside analog with profound in vitro anti-cancer activity. First identified in a high-throughput screen for inhibitors of p21 mRNA expression, subsequent experiments showed that ARC also repressed expression of hdm2 and survivin, leading to its classification as a global inhibitor of transcription 1. The following Hu U133 plus 2.0 arrays represent single time point (24 hour) gene expression analysis of transcripts altered by ARC treatment. Arrays for the other compounds (sangivamycin and doxorubicin) are included as comparators.
Publication Title
ARC (NSC 188491) has identical activity to Sangivamycin (NSC 65346) including inhibition of both P-TEFb and PKC.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Insulin degrading enzyme (IDE) is a major enzyme responsible for insulin degradation in the liver. The modulation of insulin degrading enzyme activity is hypothesized to be a link between T2DM and liver cancer. Results provide insight into role of IDE in proliferation and other cell functions.
Publication Title
Modulation of insulin degrading enzyme activity and liver cell proliferation.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Functional alterations in medial temporal lobe structures, particularly the hippocampus, are central to age-related deficits in episodic memory. Research in aging laboratory animals has characterized physiological and cellular alterations in the hippocampus that occur in association with the presence and severity of such cognitive impairment. The current study compares alterations across hippocampal subregions by gene expression profiling in a rat model that closely mirrors individual differences in neurocognitive features of aging humans across a spectrum of outcomes, including both impaired memory and preserved function. Using mRNA profiling of the CA1, CA3 and dentate gyrus subregions, we have distinguished between gene groups and pathways related to chronological age and those specifically associated with impaired or preserved cognitive ability in aged rats. We confirmed earlier reported changes in gene groups related to inflammation and oxidative stress in multiple subregions and found these to be more associated with chronological age than cognitive function per se. The CA3 profile was best able to segregate aged impaired, aged unimpaired and young subject groups from each other. Characterization of gene changes that distinguished preserved from impaired function among the aged animals found altered expression of synaptic plasticity and neurodegenerative disease-related genes. Together these gene changes suggest recruitment of adaptive mechanisms that mediate synaptic plasticity to maintain function and structural integrity in aged unimpaired rats that does not occur in aged impaired animals.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
In gastrulation, distinct progenitor cell populations are induced and sorted into the three germ layers ectoderm, mesoderm and endoderm. In order to identify genes involved in germ layer specification and morphogenesis, we identified genes differentially expressed between ectodermal and mesendodermal progenitor cells. To do so, we first generated highly enriched pools of ectodermal and mesendodermal progenitor cells. Mesendodermal cells were generated by over-expressing the Nodal signal Cyclops in wild type embryos and ectodermal cells were taken from mz-one-eyed-pinhead (oep) mutant embryos. We then compared the transcriptome of ectodermal versus mesendodermal cells taken from embryos at 7 hours post fertilization (hpf). In wild type embryos at this stage (70% epiboly), the first ectodermal and mesendodermal progenitor cells have already been sorted into their respective germ layers and ingression of mesendodermal progenitors is still ongoing.

Identification of regulators of germ layer morphogenesis using proteomics in zebrafish.
