- Illumina HumanHT-12 V4.0 expression beadchip
Description
242 patients recruited from an early arthritis clinic donated RNA and DNA from freshly isolated and purified peripheral blood CD19+ B cells. Global gene expression measurement was carried out using Illumina BeadChip HT12v4 microarrays. Objectives included the identification of B cell transcripts differentially expressed between disease phenotypes, where all patients were naive to immunomodulatory therapy. In addition an eQTL analysis was carried out with reference to known genotype data for this cohort of patients

- Affymetrix Human Genome U133A 2.0 Array (hgu133a2), Illumina Genome Analyzer IIx
Description
mRNA expression was assayed from bronchial epithelial cell samples from smokers with and without lung cancer. A subset of the samples (2 of the lung cancer samples and 3 of the no cancer samples) were pooled and underwent whole transcriptome sequencing. The goals were to compare whole transcriptome sequencing gene expression levels to gene expression levels derived from these samples run on the Affymetrix HGU133A 2.0 platform.

Illumina Genome Analyzer IIx
Description
mRNA expression was profiled from pooled bronchial airway epithelial cell brushings (n=3 patients/pool) obtained during bronchoscopy from healthy never (NS) and current smokers (S) and smokers with (C) and without (NC) lung cancer Overall design: 4 samples were sequened, each representing a pool of 3 patients. The phenotypes of the 4 samples were as follows: healthy non-smoker, healthy smoker, smoker without lung cancer and smoker with lung cancer.

Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
Mitochondrial dysfunction has been directly or indirectly implicated in the pathogenesis of a number of neurodegenerative disorders including Parkinson's disease, Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS). We used exon-sentive microarrays to characterize the responses to different mitochondrial perturbations in cellular models. We examined human SH-SY5Y neuroblastoma cells treated with paraquat, a neurotoxic herbicide which both catalyzes the formation of reactive oxygen species (ROS) and induces mitochondrial damage in animal models, and SH-SY5Y cells stably expressing the mutant SOD1(G93A) protein, one of the genetic causes of ALS. We identified a common set of genes that have a deregulated transcription and alternative splicing in both models. Noticeably, pathway analysis revealed that the expression of a subset of genes involved in neuritogenesis and axon guidance is perturbed, suggesting that alterations of axonal function may descend directly from mitochondrial damage and be responsible for neurodegenerative conditions.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Cytologically normal airway epithelial samples were collected during bronchoscopy of current and former smokers. Subjects enrolled in this study were either under suspicion of having lung cancer, had dysplasia in their airway, or were a healthy current, former or never smoker. We supplemented existing GEO series (GSE4115 and GSE7895) with the samples in this study to explore PI3K pathway activity in the these cohorts.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
RNA was obtained from histologically normal bronchial epithelium of smokers during time of clinical bronchoscopy from relatively accessible airway tissue. Gene expression data from smokers with lung cancer was compared with samples from smokers without lung cancer. This allowed us to generate a diagnostic gene expression profile that could distinguish the two classes. This profile could provide additional clinical benefit in diagnosing cancer amongst smokers with suspect lung cancer.
