Description
The goal of this study was to determine if blood circulating monocytes of metastatic breast cancer patient would express a different activation profile compared to healthy donors, in order to use this specific changesas biomarkers to monitor then response to therapy Overall design: CD11b+ cells were extracted from all blood of 4 healthy donors and 4 metastatic breast cancer patients using magnetic beads separation (Miltenyi). CD11b+ cells were then lysed and mRNA was extracted to perform RNASeq.

Description
We measured gene expression of D. melanogaster female heads and abdomens after mating with males from six populations evolved under either enforced monogamy (no male-male competition, 3 populations) or sustained polygamy (intense male-male competition, 3 populations). Overall design: Three samples of virgin female heads and six samples of mated female heads (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. Also, three samples of virgin female abdomens and six samples of mated female abdomens (one each per male evolved population, of which there are three monogamous and three polygamous), for nine libraries. In total, eighteen libraries sequenced in 8 lanes.

Description
Autosomal recessive polycystic kidney disease is a severe, monogenetically inherited kidney and liver disease and PCK rats carrying the orthologous mutant gene serve as a model of human disease. We combined selective MALDI imaging of sulfated kidney lipids and Fisher discriminant analysis of imaging data sets for identification of candidate lipid markers of progressive disease in PCK rats. Our study highlights strong increases in lower mass lipids as main classifiers of cystic disease. Structure determination by high resolution mass spectrometry identifies these altered lipids as taurine-conjugated bile acids. Beside increased levels of serum-cholesterol these sulfated lipids are selectively elevated in the PCK rat model but not in models of related hepatorenal fibrocystic diseases suggesting that they be molecular markers of the disease.

Description
Hypercapnia, the elevation of CO2 in blood and tissues, commonly occurs in severe acute and chronic respiratory diseases, and is associated with increased risk of mortality. Recent studies have shown that hypercapnia adversely affects innate immunity, host defense, lung edema clearance, and cell proliferation. Airway epithelial dysfunction is a feature of advanced lung disease, but the effect of hypercapnia on airway epithelium is unknown. Thus, in the current study we examined the effect of normoxic hypercapnia (20% CO2 for 24 h) vs normocapnia (5% CO2), on global gene expression in differentiated normal human airway epithelial cells. Gene expression was assessed on Affymetrix microarrays, and subjected to gene ontology analysis for biological process and cluster-network representation. We found that hypercapnia downregulated the expression of 183 genes and upregulated 126. Among these, major gene clusters linked to immune responses and nucleosome assembly were largely downregulated, while lipid metabolism genes were largely upregulated. The overwhelming majority of these genes were not previously known to be regulated by CO2. These changes in gene expression indicate the potential for hypercapnia to impact bronchial epithelial cell function in ways that may contribute to poor clinical outcomes in patients with severe acute or advanced chronic lung diseases.

Description
Mouse skin fibroblasts (MSFs) were obtained from a FASST (Fibroblasts Accelerate Stromal-Supported Tumorigenesis) mouse. This mouse model allows for spatial and temporal control for senescence induction by using a stromal specific Cre-recombinase driven by the pro-collagen-alpha II promoter. The stromal specific Cre activates expression of the p27IRESGFP transgene that is expressed from the ROSA locus. We cultured the MSFs in vitro, induced senescence using 10uM tamoxifen added to the media. Non-senescent cells were treated with equal volume of vehicle alone (ethanol). Upon tamoxifen treatment, cells were moved to a modular incubation chamber and maintained at 3% oxygen at 37 degrees celcius for 12 days total before collection. At the time of collection, cells were trypsynized and pelleted by centrifugation. The cells were lysed using Trysol reagent and RNA was isolated using a RiboPure RNA isolation kit (Ambion). Overall design: For this study, 2 treatment groups were analyzed (non-senescent, EtOH samples and senescent, TAM samples). Each treatment group was performed 3 times for a total of 6 samples for analysis. The gene expression analysis is a comparison of expression in senescent (TAM) vs non-senescent (EtOH) mouse skin fibroblasts.
