- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Rats with adenine-induced chronic renal failure (A-CRF) develop a reduction in the rate of relaxation of the thoracic aorta. The primary aim of this study was to elucidate the mechanisms underlying this abnormality. Male Sprague-Dawley rats received either chow containing adenine or were pair-fed with normal chow (controls). After 8-14 weeks arterial functions were analyzed ex vivo using wire myography and the thoracic aorta was analyzed by DNA microarray.
Publication Title
Adenine-induced chronic renal failure in rats decreases aortic relaxation rate and alters expression of proteins involved in vascular smooth muscle calcium handling.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Mutations in the gene encoding the transcription factor AutoImmune REgulator (AIRE) are responsible for the Autoimmune PolyEndocrinopathy Candidiasis Ecodermal Dystrophy syndrome. AIRE directs expression of tissue restricted antigens in the thymic medulla and in lymph node stromal cells and thereby substantially contributes to induction of immunological tolerance to self-antigens. Data from experimental mouse models showed that AIRE-deficiency leads to impaired deletion of autospecific T cell precursors. However, a potential role for AIRE in the function of regulatory T cell populations, which are known to play a central role in prevention of immunopathology, has remained elusive. Regulatory T cells of CD8+CD28low phenotype efficiently control immune responses in experimental autoimmune and colitis models in mice. We here show that CD8+CD28low Treg from AIRE-deficient mice are transcriptionally and phenotypically normal, exert efficient suppression of in vitro immune responses, but completely fail to prevent experimental colitis in vivo. Our data therefore demonstrate that AIRE plays an important role in the in vivo function of a naturally occurring regulatory T cell population.

Description
The peroxisome proliferator-activated receptor-coactivator-11 (PGC-11) regulates genes involved in energy metabolism. Increasing adipose tissue energy expenditure through PGC-11 activation has been suggested to be beneficial for systemic metabolism. Pharmacological PGC-11 activators could be valuable tools in the fight against obesity and metabolic disease. Finding such compounds has been challenging partly because PGC-11 is a transcriptional coactivator with no known ligand-binding activities. Importantly, PGC-11 activation is regulated by several mechanisms but protein stabilization is a limiting step as the protein has a short half-life under unstimulated conditions.
Publication Title
Small molecule PGC-1α1 protein stabilizers induce adipocyte Ucp1 expression and uncoupled mitochondrial respiration.

Description
Gene transcripts and proteins expressed during disease pathogenesis identify targets for therapy. We performed microarray analysis of histologically characterized multiple sclerosis (MS) brain lesions in comparison with control brain samples to identify differentially expressed molecules. We identified CD47 as a target of interest and studied its biology in MS and EAE.
Publication Title
Janus-like opposing roles of CD47 in autoimmune brain inflammation in humans and mice.

- Affymetrix Human Genome U95 Version 2 Array (hgu95av2)
Description
NHEK cells were plated at a density of 8 x 10 000/cm2 and the cell cultures were grown for 24 hours before addition of 2 mM N-Acetyl-L-Cystein. RNA obtained from cultures grown for 1, 12 and 24 hrs after NAC treatment were compared to RNA from untreated cells at the corresponding time points. I.e 1 hour NAC treated vs 1 hour untreated cells etc. Each EXTRACT represents an individual mRNA extraction and subsequent cDNA synthesis from a batch of totalRNA originating from one cellculture dish.

Description
Caco-2 human colon carcinoma cells were seeded at a density of 9 x 10 000 cells/cm2 and the cell cultures were grown for 24 hours before addition of 10 mM N-Acetyl-L-Cystein. RNA obtained from cultures grown for 1, 12 and 24 hrs after NAC treatment were compared to RNA from untreated cells at the corresponding time points. I.e 1 hour NAC treated vs 1 hour untreated cells etc. Each "SAMPLE" represents a biological replicate (i.e. separate cellcultures treated similarily) although I have given identical SAMPLE numbers in pairs.

Illumina HiSeq 2000
Description
We extracted RNA from whole cells and RNA from the cytoplasm and performed RNA sequening to compare differences in gene expression level and investigate what is the most appropriate estimate of the amount of mRNA present in a given cell population. The study was based on three human cell lines. Overall design: Analyze of transcriptome in 3 human cell lines (U-2 OS, A-431, U-251MG). Each cell line was prepared with four biological replicates for total RNA and four for cytoplasmic RNA.
Publication Title
Comparison of total and cytoplasmic mRNA reveals global regulation by nuclear retention and miRNAs.
