In this experiment we catalogue transcriptional changes accompanying COPD in the quadriceps. We measure global gene transcription in the quadriceps using Affymetrix HuGene 1.1 ST arrays in an unselected cohort of 79 stable COPD patients in secondary care and 16 healthy age-and gender-matched controls.
COPD is accompanied by co-ordinated transcriptional perturbation in the quadriceps affecting the mitochondria and extracellular matrix.

View SamplesChanges in the respiratory microbiome are associated with disease progression in Idiopathic pulmonary fibrosis (IPF). The role of the host response to the respiratory microbiome however remains unknown. The role of this study is to explore the host-microbial interaction in IPF. Network analysis of gene expression data identified two gene modules that strongly associate with a diagnosis of IPF, BAL bacterial burden (determined by 16S quantitative PCR) and specific microbial OTUs, as well as lavage and peripheral blood neutrophilia. Genes within these modules that are involved in the host defence response include NLRC4, PGLYRP1, MMP9, DEFA4. The modules also contain two genes encoding specific antimicrobial peptides (SLPI and CAMP). Many of these particular transcripts were associated with survival and showed longitudinal over expression in subjects experiencing disease progression, further strengthening their relationship with disease. Integrated analysis of the host transcriptome and microbial signatures demonstrates an apparent host response to the presence of an altered or more abundant microbiome. These responses remain elevated on longitudinal follow up, suggesting that the bacterial communities of the lower airways may be acting as persistent stimuli for repetitive alveolar injury in IPF.

View SamplesTo gain a more depth knowledge of repressive epigenetic gene regulation in UCC, we have profiled H3K9m3 and H3K27m3 in normal and malignant urothelial cells. We matched these profiles to those 5-methylcytosine and gene expression. We hypothesized that differences represent pro-carcinogenic events within the urothelium.

View SamplesThe complexity of the mature adult brain is a result of both developmental processes and experience-dependent circuit formation. One way to look at the process of brain development is to examine gene expression changes, and previous studies have used microarrays to address this in a global manner. However, the transcriptome is more complex than gene expression levels alone, as both alternative splicing and RNA editing occur to generate a more diverse set of mature transcripts. The aim of the current study was to develop a high-resolution transcriptome dataset of mouse cortical development using RNA sequencing (RNA-Seq), thus assaying exon usage and RNA editing as well as overcoming some of the inherent limitations of microarrays. We found a large number of differentially expressed genes, but also altered splicing and RNA editing between embryonic and adult cerebral cortex. Each dataset was validated both technically and biologically, and in each case tested we found our RNA-Seq observations to have high predictive validity. We propose this dataset, and the accompanying analysis, to be a helpful resource in the understanding of changes in gene expression during development.

View SamplesSelection of B cells subjected to hypermutation in germinal centres (GC) during T-dependent (TD) antibody responses yields memory cells and long-lived plasma cells that produce high affinity antibodies biased to foreign antigens rather than self-antigens. GC also form in T-independent (TI) responses to polysaccharide antigens but failed selection results in GC involution and memory cells are not generated. To date there are no markers that allow phenotypic distinction of T-dependent and T-independent germinal centre B cells. We have now compared the global gene expression of GC B cells purified from mice immunized with either TD or TI antigens and identified eighty genes that are differentially expressed in TD GC.
Axon growth and guidance genes identify T-dependent germinal centre B cells.
