Affymetrix Mouse Expression 430A Array (moe430a)
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.

Description
TGF-beta1 is the major cytokine driver of fibrotic scarring observed in diabetic nephropathy and other fibrosis-related diseases. RNA-sequencing offers the potential for more sensitive assessment of the TGF-ß1-driven transcriptome. Overall design: There were two treatment groups: vehicle, 48 hr TGFb1. Each treatment was carried out in triplicate. Upon quality control assessment, one TGFß1 treated sample was excluded from further analyses, leaving 3 unstimulated and 2 TGFß1 samples.

- Affymetrix Human Exon 1.0 ST Array [transcript (gene) version (huex10st)
Description
To identify individual genes with potential diagnostic and therapeutic utilities in lung cancer, we performed gene expression profiling out of a broad coverage of human transcriptome using clinical patient tissues. Six RNA samples extracted from five cancerous tissues and one normal control were subjected to Affymetrix gene array analysis using Human Exon 1.0 ST Array. Data were further processed using Expression Console and Transcriptome Analysis Console softwares. Both core-gene expression analysis and extended-gene expression analysis were performed to discover significantly regulated genes associated with lung cancer progression.

Description
Hepatic iron overload is a risk factor for progression of hepatocellular carcinoma (HCC), although the molecular mechanisms underlying this association have remained unclear. We now show that the iron-sensing ubiquitin ligase FBXL5 is previously unrecognized oncosuppressor in liver carcinogenesis in mice. Hepatocellular iron overload evoked by FBXL5 ablation gives rise to oxidative stress, tissue damage, inflammation and compensatory proliferation in hepatocytes and to consequent promotion of liver carcinogenesis induced by exposure to a chemical carcinogen. The tumor-promoting effect of FBXL5 deficiency in the liver is also operative in a model of virus-induced HCC. FBXL5-deficient mice thus constitute the first genetically engineered mouse model of liver carcinogenesis induced by iron overload. Dysregulation of FBXL5-mediated cellular iron homeostasis was also found to be associated with poor prognosis in human HCC, implicating FBXL5 plays a significant role in defense against hepatocarcinogenesis. Overall design: Total RNA was extracted from the nontumor and tumor tissue of an Alb-Cre/Fbxl5F/F male mouse (nontumor, n = 5; tumor, n = 5) or two littermate control Fbxl5F/F mice (nontumor, n = 6; tumor, n = 6) at 45 weeks of age.

Description
Ischemic heart failure after acute myocardial infarction (AMI) is a major cause of morbidity and mortality worldwide. We recently reported that activation of a trans-valvular axial-flow pump in the LV and delaying myocardial reperfusion, known as Primary Unloading, limits infarct size by reducing LV wall stress and increasing expression of the cardioprotective cytokine, stromal derived factor 1 alpha (SDF1a). The mechanisms underlying the cardioprotective benefit and sustained effect of Primary Unloading remain poorly understood. We now tested the importance of delayed reperfusion, the functional significance of SDF1a, and the late-term impact on myocardial function and scar size associated with Primary Unloading.

Description
To identify signaling pathways that are differentially regulated in human gliomas, a microarray analysis on 30 brain tumor samples (12 primary glioblastomas (GBM), 3 secondary glioblastomas (GBM-2), 8 astrocytomas (Astro) and 7 oligodendrogliomas (Oligo)) and on 5 glioblastoma cell lines (LN018, LN215, LN229, LN319 and BS149) was performed. Normal brain tissue (NB) and normal human astrocytes (NHA) were used as a control. Kinase expression in each tumor was compared to expression in normal brain and expression values from normal human astrocytes were used as an additional control.
