Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Choroid plexuses (CP) develop early during development. They form a barrier between the blood and the cerebrospinal fluid, and fulfill important protective and nutritive functions. We used Affymetrix microarrays to assess whether CP of the lateral ventricles (LVCP) have similar functions in developing and adult brain. We identified distinct families of protective and transport genes and found that most of these genes were already well expressed during development.
Publication Title
Developmental changes in the transcriptome of the rat choroid plexus in relation to neuroprotection.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
RNA from circulating blood reticulocytes was utilized to provide a robust description of genes transcribed at the final stages of erythroblast maturation. After depletion of leukocytes and platelets, Affymetrix HG-U133 arrays were hybridized with probe from total RNA isolated from blood sampled from 14 umbilical cords and 14 healthy adult humans.

Description
Satellite cells are the primary source of stem cells for skeletal muscle growth and regeneration. Since adult stem cell maintenance involves a fine balance between intrinsic and extrinsic mechanisms, we performed genome-wide chronological expression profiling to identify the transcriptomic changes involved during early postnatal growth till acquisition of satellite cell quiescence.

- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
Barretts esophagus (BE) is a metaplastic precursor lesion of esophageal adenocarcinoma (EA), the most rapidly increasing cancer in western societies. While the prevalence of BE is increasing, the vast majority of EA occurs in patients with undiagnosed BE. Thus, we sought to identify genes that are altered in BE compared to the normal mucosa of the esophagus, and which may be potential biomarkers for the development or diagnosis of BE.
Publication Title
Global changes in gene expression of Barrett's esophagus compared to normal squamous esophagus and gastric cardia tissues.

Description
We analyed the gene expression profiles after knocking down MYCN or TFAP4. Results showed that transcription factor MYCN and TFAP4 commonly regulats a subset of genes that may contribute to neuroblastoma cells proliferation and migration.

Illumina HiSeq 2000
Description
We sequenced mRNA extracted from heads of a D. melanogaster population that was sedated with a stream of ethanol saturated vapor, 30 minutes before RNA extraction; and from an age-matched untreated control group. Differential gene expression between the two groups was calculated and reported. Overall design: Examination of mRNA levels in heads of D. melanogaster adult females after ethanol exposure was performed using next generation sequencing (NGS) technology.

Description
To study the effect of structural changes on expression, we assessed gene expression in genomic disorder mouse models. Both a microdeletion and its reciprocal microduplication mapping to mouse chromosome 11 (MMU11), which model the rearrangements present in Smith-Magenis (SMS) and Potocki-Lupski (PTLS) syndromes patients, respectively, have been engineered. We profiled the transcriptome of five different tissues affected in human patients in mice with 1n (Deletion/+), 2n (+/+), 3n (Duplication/+) and uniallelic 2n (Deletion/Duplication) copies of the same region in an identical genetic background. The most differentially expressed transcripts between the four studied genotypes were ranked. A highly significant propensity, are mapping to the engineered SMS/PTLS interval in the different tissues. A statistically significant overrepresentation of the genes mapping to the flanks of the engineered interval was also found in the top-ranked differentially expressed genes. A phenomenon efficient across multiple cell lineages and that extends along the entire length of the chromosome, tens of megabases from the breakpoints. These long-range effects are unidirectional and uncoupled from the number of copies of the copy number variation (CNV) genes. Thus, our results suggest that the assortment of genes mapping to a chromosome is not random. They also indicate that a structural change at a given position of the human genome may cause the same perturbation in particular pathways regardless of gene dosage. An issue that should be considered in appreciating the contribution of this class of variation to phenotypic features.
