Affymetrix Human Genome U133A Array (hgu133a)
Description
AQM shows acute muscle wasting and weakness. Key aspects of AQM include muscle atrophy and myofilament loss. Gene expression profiling, using muscle biopsies from AQM, neurogenic atrophy and normal controls, showed that both myogenic and neurogenic atrophy share induction of myofiber-specific ubiquitin/proteosome pathways while only the AQM shows a specific strong induction of transforming growth factor (TGF)-beta/MAPK pathways.

Description
Albeit increased serum CK level and abnormal muscle histology are always present, boys with DMD are phenotipically indistinguishable from the normal ones at birth and, in their first years of life, acquire early motor milestones at normal times. A clear defect in muscle function becomes generally apparent by the end of the second year. As the disease is typically diagnosed between the ages of 3 and 7, the first two years are often considered and referred to as clinically presymptomatic.

Description
A large amount of epidemiologic data supports a role for chronic inflammation in epithelial carcinogenesis. In the lung, several studies have found that smokers with chronic obstructive pulmonary disease (COPD), an inflammatory disease of the airways and alveoli, have an increased risk of lung cancer (1.3 to 4.9 fold) compared to smokers without COPD. We have also shown that COPD-like airway inflammation induced by an aerosolized lysate of non-typeable Hemophilus influenzae (NTHi) promotes lung cancer in a Clara cell-targeted K-ras mutant mouse model (CC-LR) of lung cancer. In contrast, existing epidemiologic data suggest that allergic inflammation of the airways may be protective against lung cancer. We tested this association in a mouse model of allergic airway inflammation. CC-LR mice were sensitized to ovalbumin by intraperitoneal injection weekly for two weeks, then challenged for 30 min to an aerosol of ovalbumin in 0.9% saline weekly for eight weeks. This resulted in eosinophilic lung inflammation associated with increased levels of T helper 2 (Th2) cytokines and mucous metaplasia of airway epithelium, similar to what is seen in asthma patients. However, consistent with epidemiologic data, this type of inflammation did not result in any significant differences in lung surface tumor number (22 3 in OVA exposed vs 26 6 in control mice). We conclude that asthma-like (Th2) inflammation does not promote lung carcinogenesis in a Ras-initiated background, and demonstrate a clear specificity for the nature of inflammation in lung cancer promotion. These findings will assist in determination of the essential cells and signaling events in lung cancer promotion by inflammation.

Description
To get insight in the functional role of EGR2 for Ewing sarcoma, we performed a transcriptional profiling of Ewing sarcoma cells after knockdown of EGR2 and compared the resulting transcriptional signature with that of EWSR1-FLI1-silenced Ewing sarcoma cells. In accordance with the strong EGR2-induction by EWSR1-FLI1, both genes highly significantly overlap in their transcriptional signatures. Gene-set enrichment analyses (GSEA) and DAVID (Database for Annotation, Visualisation and Integrated Discovery) gene ontology analyses indicated a strong impact of EGR2 on cholesterol and lipid biosynthesis resembling its function in orchestrating lipid metabolism of myelinating Schwann cells.

Description
To try to identify the mechanism of STAT3s indirect action we have used a genomic approach to map the binding sites of STAT3 within the genome and also used RNA-seq technology to map the changes in RNA expression and transcript isoform abundance in response to IL-10. Overall design: Examination of transcriptome changes in peritoneal macrophages when treated with IL-10 for 4 hours. RNA was extracted and sequenced.
