Description
An investigation of gene expression changes in rectal biopsies from donors with IBS compared to controls to begin to understand this complex syndrome. To further investigate differences between IBS groups (constipation and diarrhoea predominant) (part1) and how IBS relates to bacterial infection (part2) with biopsies taken 6 months after Campylobacter jejuni infection.

Description
In order to better understand the systemic immunological responses in a clinical cohort of obese and non-obese asthmatics and healthy subjects, we sought to analyze gene expression from whole blood. We collected whole blood samples from 156 donors and performed gene expression analysis of these samples and identified differentially expressed genes (DEGs) in each obese and/or asthma group relative to healthy volunteers.

Description
Induced sputum is used to sample inflammatory cells, predominantly neutrophils and macrophages, from the airways of COPD patients. Our aim was to identify candidate genes associated with the degree of airflow obstruction and the extent of emphysema by expression profiling, and then to confirm these findings for selected candidates using specific PCR and protein analysis.

Description
Epigenetic dysregulation has emerged as an important mechanism in cancer. Alterations in epigenetic machinery have become a major focus for new targeted therapies. The current report describes the discovery and biological activity of a cyclopropylamine containing inhibitor of Lysine Demethylase 1 (LSD1), GSK2879552. This small molecule is a potent, selective, orally bioavailable, mechanism-based irreversible inhibitor of LSD1. A proliferation screen of cell lines representing a number of tumor types indicated that small cell lung carcinoma (SCLC) is sensitive to LSD1 inhibition. The subset of SCLC lines and primary samples that undergo growth inhibition in response to GSK2879552 exhibit DNA hypomethylation of a signature set of probes suggesting this may be used as a predictive biomarker of activity. The targeted mechanism coupled with a novel predictive biomarker make LSD1 inhibition an exciting potential therapy for SCLC, a highly prevalent, rarely cured, tumor type representing approximately 15% of all lung cancers.

Description
Skeletal muscle has an impressive ability to repair itself after a damaging insult and this response is essential to the process of muscle adaptation. In conditions such as muscular dystrophy and the sarcopenia of old age, repair is compromised leading to fibrosis and fatty tissue accumulation. Hypoxia-inducible factors (HIFs) are highly conserved regulators of gene transcription under conditions of low oxygen tension and HIF target genes such as EPO and VEGF have been associated with muscle protection and repair. We sought to interrogate the importance of HIF activation to skeletal muscle repair through the use of prolyl hydroxylase inhibitors (PHI) that stabilize HIF and activate target gene transcription in a mouse eccentric exercise limb damage model.

Description
Growing evidence indicates that PPAR agonists, such as rosiglitazone (RSG,), induce adipose mitochondrial biogenesis. Using microarrays, we systematically analyzed nucleus-encoded mitochondrial gene expression in two common murine adipocyte models, 3T3 L1 and C3H/10T1/2 adipocytes, and aimed to further establish the direct role of RSG, and capture the temporal changes in mitochondrial gene transcription during this process.

Description
COPD is a disorder characterized by the progressive development of airflow limitation that is not fully reversible. Cigarette smoke has been generally accepted as the most important of many risk factors for the development of COPD.
