Description
Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disease which is characterized by premature ageing. Affected children show accelerated cardiovascular disease, including atherosclerosis and vascular smooth muscle cell (VSMC) loss, and die at an average age of 14.6 years from myocardial infarction or stroke. The objective of this study was to detect the primary mechanism leading to VSMC death and accelerated atherosclerosis in mouse models of HGPS. In our RNA sequencing experiment we compared transcriptomes of medial aortas from both ubiquitous and VSMC-specific progeric models with its corresponding controls expressing lamin A/C or lamin C only, respectively. Our studies might not only help to find a cure for HGPS but also shed some light on physiological ageing.

- Affymetrix Rat Expression 230A Array (rae230a)
Description
We have compared the gene-expression in cerebral arteries from rats after experimental SAH with the expression in cerebral vessels from sham operated animals. The model is well characterised (Prunell et al. 2003; Prunell et al. 2004) regarding the physiological changes but not regarding the gene expression pattern. Male Sprague-Dawley rats (350-400 g) were anaesthetized using 5% halothane (Halocarbon Laboratories, River Edge, New Jersey) in N2O/O2 (30:70). The rat was intubated and artificially ventilated with inhalation of 0.5-1.5% halothane in N2O/O2 (70:30) during the surgical procedure. The depth of anaesthesia was carefully monitored and the respiration checked by regularly withdrawing arterial blood samples for blood gas analysis (Radiometer, Copenhagen, Denmark). An arterial catheter to measure blood pressure was placed in the tail artery and a catheter to monitor intracranial pressure (ICP) was placed in the subocciptal membrane. At either side of the skull, 3 mm from the midline and 4 mm anteriorly from the bregma, holes were drilled through the skull bone down to dura mater (without perforation) allowing the placement of two laser-Doppler flow probes to measure CBF. Finally, a 27G blunt canula with side hole was introduced stereotactically 6.5 mm anterior to bregma in the midline at an angle of 30 degrees to the vertical. After 30 minutes of equilibration 250 ul blood was withdrawn from the tail catheter and injected intracranially at a pressure equal to the mean arterial blood pressure (80-100 mmHg). Subsequently the rat was kept under anaesthesia for another 60 minutes to allow recovery from the cerebral insult after which catheters were removed and the incisions closed. The rat was then revitalized and extubated. A subcutaneous injection of carprofen (4.0 mg/kg) (Pfizer, Denmark) was administered and the rat was hydrated subcutaneously using 40 ml isotonic sodium chloride at the end of the operation and at day one. During the period of observation the rat was monitored regularly, and if showing severe distress the animal was prematurely killed. In addition, a series of sham-operated rats were prepared. They went through the same procedure with the exception that no blood was injected intracisternally.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
APE1 regulates a vast majority of genes by acting as a transcriptional co-activator or as a co-repressor. It is overexpressed in diverse cancer tissues and is associated with their drug resistance. It is essential for cell proliferation. APE1 is post-translationally acetylated by HAT p300 at its N-terminal Lys 6 and 7 residues. We examined APE1 and its acetylation-dependent gene expression profile of lung cancer cells which would contribute to sustained proliferation of lung cancer cells.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Endothelial cells comprise a key component of the inflammatory response. HUVEC (human umbilical vein endothelial cells) were stimulated with interleukin-1 for 0, 0.5, 1, 2.5 and 6 hours, and analyzed using Affymetrix U133A microarrays, in order to obtain a comprehensive overview of the immediate early to early gene expression profiles. HUVEC were isolated and cultured on gelatine-coated cell culture dishes in M199 medium supplemented with 20% FCS, antibiotics, ECGS (endothelial cell growth supplement) and Heparin as described by Zhang et al., Blood 1996;88:3880-3886. HUVEC were stimulated with 100 U/ml human IL-1 (Biosource) for various periods of time, and total RNA isolated using the RNeasy kit (Qiagen) according to the manufacturer's instructions. Hybridization to one set of human U133A GeneChips (Affymetrix, Santa Clara, CA) and scanning of the arrays was carried out according to manufacturers protocols (https://www.affymetrix.com). Briefly, 5 g of total RNA was used to generate double-stranded cDNA by reverse transcription using a cDNA synthesis kit (Superscript Choice System; Life Technologies, Inc., Rockville, MD) that uses an oligo(dT)24 primer containing a T7 RNA polymerase promoter 3' to the polyT (Geneset, La Jolla, CA), followed by second-strand synthesis. Labeled cRNA was prepared from the double-stranded cDNA by in vitro transcription using T7 RNA polymerase in the presence of biotin-11-CTP and biotin-16-UTP (Enzo, Farmington, NY). The labeled cRNA was purified over RNeasy columns (Qiagen, Valencia, CA). Fifteen g of cRNA was fragmented at 94C for 35 minutes in 40 mmol/L of Tris-acetate, pH 8.1, 100 mmol/L of potassium acetate, and 30 mmol/L of magnesium acetate. The cRNA was then used to prepare 300 l of hybridization cocktail (100 mmol/L MES, 1 mol/L NaCl, 20 mmol/L ethylenediaminetetraacetic acid, 0.01% Tween 20) containing 0.1 mg/ml of herring sperm DNA (Promega, Madison, WI) and 500 g/ml of acetylated bovine serum albumin (Life Technologies, Inc.). Before hybridization, the cocktails were heated to 94C for 5 minutes, equilibrated at 45C for 5 minutes, and then clarified by centrifugation (16,000 x g) at room temperature for 5 minutes. Aliquots of this hybridization cocktail containing 15 g of fragmented cRNA were hybridized to HU133A arrays (Affymetrix, Santa Clara, CA) at 45C for 16 hours in a rotisserie oven at 60 rpm. The arrays were washed using non-stringent buffer (6xSSPE: 0.9 M sodium chloride, 0.06 M sodium phosphate, 6 mM EDTA pH 7.4) at 25C, followed by stringent buffer (100 mmol/L MES, pH 6.7, 0.1 mol/L NaCl, 0.01% Tween 20) at 50C. The arrays were stained with streptavidin-phycoerythrin (Molecular Probes, Eugene, OR), washed with 6xSSPE, incubated with biotinylated anti-streptavidin IgG, stained again with streptavidin-phycoerythrin, and washed again with 6xSSPE. The arrays were scanned using the GeneArray scanner (Affymetrix). Image analysis was performed with GeneChip software (Affymetrix, MAS 5.0). Normalization was performed by global scaling, with the arrays scaled to an average intensity of 500.
