This study identified genomwide KCl inducible readthrough transcription. The project also includes a Cap-Seq experiment to identify transcriptional start sites, demonstrating that KCl does not activate downstream transcriptional start sites, but indeed does induce readthrough

View SamplesThe AIL transcription factor BABY BOOM (BBM) is required together with the related PLETHORA proteins for embryo and root meristem development and its expression is sufficient to confer pluripotency and totipotency to somatic tissues. We show that BBM and other AIL proteins interact with multiple members of the L1/epidermal-expressed HD-ZIP class IV / HOMEODOMAIN GLABROUS (HDG) transcription factor family. Ectopic overexpression of HDG1, HDG11 and HDG12 genes induces a reduced growth phenotype, and analysis of HDG1 overexpression lines shows that this growth reduction is due to both root and shoot meristem arrest. To understand how HDG1 controls cell proliferation, as well as its functional relationship with BBM, we performed microarray experiments to identify candidate genes that are directly regulated by HDG1, and compared these to the set of genes that are directly regulated by BBM expression.
AIL and HDG proteins act antagonistically to control cell proliferation.

View SamplesThis study relates to embryo-maternal interaction. The aim was to compare the transcriptome and ability of the ipsilateral and contralateral uterine horns to support preimplantation conceptus survival and growth to Day 14. Although differences in gene expression exist between the endometrium of uterine horns ipsilateral and contralateral to the CL in cattle, they do not impact conceptus survival or length between Days 7 and 14. Overall design: The endometrial samples from both uterine horns were collected from synchronized heifers slaughtered on Day 5, 7, 13 or 16 post-estrus (n = 5 per time) and subjected to RNA sequencing.
Do differences in the endometrial transcriptome between uterine horns ipsilateral and contralateral to the corpus luteum influence conceptus growth to day 14 in cattle?

View SamplesWe analysed the transcriptional signature in endothelial cells extracted from the bone marrow of mice engrafted with human AML and compared it to the one of mice engrafted with human normal hematopoietic cells Overall design: Immunodeficient mice were transplanted with human AML cells derived from patients, or with normal human hematopoietic cells derived from cord blood. Mice were sacrificed once assessed the bone marrow engraftment, and the bones were processed to isolate endothelial cells using the CD31 marker. RNA was extracted, sequencing libraries were prepared and sequenced.

Cell line
View SamplesTo determine early changes leading to human cell transformation (cancer) we exposed an immortalized human bronchial epithelial cell line, BEAS-2B, to one of four different metals that may cause cancer via inhalation in humans or rodents: 2.0 micro-Molar soluble sodium arsenite (NaAsO2), 0.50 micro-Molar potassium chromate (K2CrO4), 250 micro-Molar nickel (II) sulfate (NiSO4), 10 micro-Molar sodium meta-vanadate (NaVO3), or were left untreated (control). After a 30-60 day exposure, cells were rinsed of metals and seeded in soft agar. A small number of the cells formed colonies in the soft agar, demonstrating the potential for anchorage independent growth, a characteristic of cancer. These colonies that originated from a single cell were extracted from the agar and grown out in monolayer for 3-4 weeks. The RNA data provided here is taken from these cells. The significance it that the metal exposure was stopped many generations before the analysis, yet each sample demonstrates changes in gene expression based on the original metal exposure.
