In an attempt to unveil part of the molecular processes controlling porcine placentation we have investigated the pregnancy induced gene expression in the porcine endometrium at Day 14 after insemination using the Affymetrix GeneChip Porcine Genome Array.

View SamplesConstitutive low level DNA damage in RNASEH2 deficiency is linked to innate immune activation. Hierarchical clustering of over 16000 transcripts revealed remarkably similar profiles in patients with lupus erythematosus and patients with AGS with up-regulation of genes involved in DNA damage signaling and type I-IFN signaling. Overall design: Comparison of transcriptional profiles of native RNASEH2-deficient patient fibroblasts with wild type cells.

View SamplesOur study involves a transcriptomic approach to the analysis of industrial yeast metabolism. Historically, among the hundreds of yeast species, Saccharomyces cerevisiae has played an important role in scientific investigations and industrial applications, and it is universally acknowledged as one of the model systems for eukaryotic organisms. Yeast is also an important component of the wine fermentation process and determines various attributes of the final product.

View SamplesHuman samples of 33 adrenocortical carcinomas, 22 adrenocortical adenomas, and 10 normal adrenal cortex samples, each from a different patient, had mRNA assays performed using Affymetrix HG_U133_plus_2 arrays, with 54675 probe-sets. We note that the same array data is in GEO series GSE33371, where we assayed the cancer samples for Beta-catenin staining or mutation, and make new comparisons based on those assays.

View SamplesTwenty-one genes (27 probe sets) were up-regulated in CAF, as compared with NF. Known functions of these genes relate to paracrine or intracellular signaling, transcriptional regulation, extracellular matrix and cell adhesion/migration. Ten genes (14 probe sets) were down-regulated in CAF, including the pluripotency transcription factor KLF4. Quantitative RTPCR analysis of 10 genes validated the array results. Immunohistochemical staining for three gene products confirmed stromal expression in terms of location and relative quantity. Surprisingly, the variability of gene expression was slightly higher in NF than in CAF, suggesting inter-individual heterogeneity of normal stroma.

View SamplesPlant roots perceive neighbouring roots even when resource depletion is low. The transcriptomic response to the presence or absence of an inferior competitor (Hieracium pilosella) is therefore examined in roots of A. thaliana. The experiment was set up in pots filled with non-sterile sand, that allowed to sample roots of eight week old Arabidopsis plants. 3 biological replicates per treatment were examined. Each of these replicates represents 3 pooled samples from individual plants.

View SamplesInterferon tau (IFNT), a Type I IFN similar to alpha IFNs (IFNA), is the pregnancy recognition signal, produced by the ruminant conceptus. To elucidate specific effects of bovine IFNT and of other conceptus-derived factors, endometrial gene expression changes during early pregnancy were compared to gene expression changes after intrauterine application of human IFNA2. In study one, endometrial tissue samples were obtained on days (D) 12, 15, and 18 post-mating from nonpregnant or pregnant heifers. In study two, heifers were treated from D14 to D16 of the estrous cycle with an intrauterine device releasing IFNA2 or placebo lipid extrudates or PBS only as controls. Endometrial biopsies were collected after flushing the uterus. All samples from both experiments were analyzed with an Affymetrix Bovine Genome Array. Study one revealed differential gene expression between pregnant and nonpregnant endometria on D15 and D18. In study two, IFNA2 treatment resulted in differential gene expression in the bovine endometrium. Comparison of the datasets from both studies identified genes that were differentially expressed in response to IFNA2 but not in response to pregnancy on D15 or D18. Vice versa, genes were found as differentially expressed during pregnancy but not after IFNA2 treatment. In study three, spatiotemporal alterations in expression of selected genes were determined in uteri from nonpregnant and early pregnant heifers using in situ hybridization. The findings of this study suggest differential effects of bovine IFNT compared to human IFNA2 and that some pregnancy-specific changes in the endometrium are elicited by conceptus-derived factors other than IFNT.
