Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Epidemiological studies have demonstrated that exposure to particulate matter (PM) ambient pollution has adverse effects on lung health, exacerbated by cigarette smoking. Fine airborne particles <2.5 m (PM2.5) are the most harmful of the urban pollutants, and the most closely linked to respiratory disease. Based on the knowledge that the small airway epithelium (SAE) plays a central role in pathogenesis of smoking-related lung disease, we hypothesized that elevated PM2.5 levels are associated with dysregulation of SAE gene expression.

Description
The pathology of chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis and the majority of lung cancers involve the small airway epithelium (SAE), the single continuous layer of cells lining the airways ?6th generations. The basal cells (BC) are the stem/progenitor cells of the SAE, responsible for the differentiation into intermediate cells and ciliated, club and mucous differentiated cells. To facilitate the study of the biology of the human SAE in health and disease, we immortalized and characterized a normal human SAE basal cell line.

Description
Treatment of severely refractory Crohns disease (CD) patients remains a clinical challenge. Recent studies show efficacy of autologous hematopoietic stem cell transplant (HSCT) in these severely compromised patients. HSCT is thought to eliminate auto-reactive cells; however the mechanisms are incompletely understood. We followed a group of patients (n=18) receiving autologous HSCT, with 50% of them achieving endoscopic drug-free remission. To elucidate the mechanism driving efficacy we compared the immunological changes induced by HSCT in responders and non-responders.

Description
Treatment of severely refractory Crohn's disease (CD) patients remains a clinical challenge. Recent studies show the efficacy of autologous hematopoietic stem cell transplant (HSCT) in these severely compromised patients. HSCT is thought to eliminate auto-reactive cells; however, no specific studies of immune reconstitution in CD patients are available. We studied a group of CD patients receiving autologous HSCT, with 50% of them achieving endoscopic drug-free remission. To elucidate the mechanism driving efficacy, we studied changes in the immune cell composition in tissue induced by HSCT. Overall design: Biopsy mRNA profiles of 14 CD patients undergoing HSCT were generated by deep sequencing, using HiSeq-4000 platform (Illumina, San Diego, CA).

Description
Study Smoking and COPD are associated with decreased mucociliary clearance and healthy smokers have shorter cilia in the large airway than nonsmokers. Intraflagellar transport (IFT) is the process by which cilia are produced and maintained. We assessed expression of IFT-related genes in smokers and nonsmokers and evaluated cilia length in the large and small airway of nonsmokers, healthy smokers, and smokers with COPD.

Description
Recently, we have shown that disturbed flow caused by partial ligation of mouse carotid artery rapidly induces endothelial dysfunction and atherosclerosis within two weeks. To understand the molecular mechanisms by which disturbed flow induces atherosclerosis, we carried out genome-wide microarray study using endothelial RNAs isolated from the flow-disturbed left and the contralateral right common carotid artery (LCA and RCA) in C57BL/6 mice.

Description
Purpose: The aim of this study is to determine the absolute and relative expression levels of mRNA transcripts across multiple flow cytometrically sorted epithelial cell types including freshly isolated CD24+CD29hi mammary stem cell-enriched basal cells (MaSC/basal), CD24+CD29loCD61+ luminal progenitor-enriched (LP) and the CD24+CD29loCD61- mature luminal-enriched (ML) cell populations. Additionally, a comparison between these primary cell types and cultured MaSC/Basal-derived mammosphere cells (mammosphere) and the CommaD-ßGeo (CommaDß) cell line was performed. Methods: Total RNA was extracted and purified from sorted luminal or basal populations from the mammary glands of female virgin 8- to 10-week-old FVB/N mice (3 independent samples per population), MaSC/Basal cells cultured for 1 week under mammosphere conditions and CommaDß cells grown under maintenance conditions (Deugnier et al. 2006). Total RNA (100 ng) was used to generate sequencing libraries for whole transcriptome analysis following Illumina’s TruSeq RNA v2 sample preparation protocol. Completed libraries were sequenced on HiSeq 2000 with TruSeq SBS Kit v3- HS reagents (Illumina) as 100 bp single-end reads at the Australian Genome Research Facility (AGRF), Melbourne. Approximately 30 million 100 bp single-end reads were obtained for each sample. Reads were aligned to the mouse reference genome mm10 and mapped to known genomic features at the gene level using the Rsubread package (version 1.14.1) (Liao et al. 2013). Single reads were then summarized into gene-level counts using FeatureCounts (Liao et al. 2014). Overall design: Total RNA was extracted and purified from sorted luminal or basal populations from the mammary glands of female virgin 8- to 10-week-old FVB/N mice (3 independent samples for population), MaSC/Basal cells cultured for 1 week under mammsophere conditions and CommaDß cells grown under maintenance conditions (Deugnier et al. 2006) and their transcriptomes analysed by RNA-Seq.

Description
Mammary glands were collected from 8 pubescent (4.7-4.9 week-old) female mice and 8 adult (10 week old) female mice. Freshly sorted epithelial cells were submitted to a Fluidigm C1 System machine for single cell capture and cDNA synthesis. Cells were visualized under the microscope to ensure integrity of the captured single cells prior to cDNA preparation. Libraries were prepared using the Nextera XT kit and sequencing was carried out on an Illumina NextSeq 500 to achieve paired-end 75 bp reads. Overall design: RNA-seq profiling was completed for 221 cells from pubescent mice and 223 cells from adult mice.
