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
We sequenced mRNA from zebrafish wild-type embryos, gata5 morphants, gata6 morphants, and gata5/6 morphants at bud and 6-somite developmental stages to identify genes co-operatively regulated by gata5 and gata6 during cardiomyocyte progenitor specification. Overall design: Samples were collected in duplicate, with 40 embryos per sample. Single 36-base pair reads were sequenced on the Illumina Genome Analyzer IIx

Description
We have sequenced the polysome-associated translating mRNAs from stage-matched wild-type and eif3ha morphant embryos at ~24 hpf stage to identify transcripts translationally regulated by eIF3ha. As a control, we have also sequenced total mRNAs from the stage-matched wild-type and eif3ha morphants as well at ~ 24 hpf. Overall design: Polysome-associated mRNAs were isolated from 300 zebrafish embryos. Total RNA was isolated from 50 zebrafish embryos. Single 36-base pair reads were sequenced on the Illumina Genome Analyzer Iix.

Description
The Gata4 transcription factor is essential for normal heart development, but the molecular basis for its function remain poorly understood. We profiled at the whole genome level transcript changes in cardiomyocytes when Gata4 is depleted from zebrafish embryos. Our objective was to elucidate the cardiomyocyte-specific molecular program functioning downstream of Gata4 in order to better understand the role of Gata4 in cardiac morphogenesis. Overall design: Six samples in total are deposited. Three replicate control samples and three replicate Gata4 morphant samples were analyzed.

Description
Distinctions between craniofacial and axial muscles exist from the onset of development and throughout adulthood. The masticatory muscles are a specialized group of craniofacial muscles that retain embryonic fiber properties throughout adulthood, suggesting that the developmental origin of these muscles may govern a pattern of expression that differs from limb muscles. To determine the extent of these differences, expression profiling of total RNA isolated from the masseter and tibialis anterior (TA) muscles of adult female mice was performed, which identified transcriptional changes in unanticipated functional classes of genes in addition to those associated with fiber type. In particular, the masseters displayed a reduction of transcripts associated with load-sensing and anabolic processes, and heightened expression of genes associated with stress. Consistent with these observations were a significantly smaller fiber cross-sectional area in masseters, significantly elevated load-sensing signaling (phosphorylated Focal Adhesion Kinase (FAK)), and increased apoptotic index in masseters compared to TA muscles. Based on these results, we hypothesize that masticatory muscles may sense and respond to load differently than limb muscles, where the drive for anabolic processes is reduced, and cell stress mediated processes are enhanced. These results establish a novel classification for the masseter muscle in the spectrum of skeletal muscle allotypes, and may provide insight into the molecular basis for specific muscle-related pathologies associated with masticatory muscles.
