Description
Invasive extravillous trophoblasts (EVTs) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue may be limited and primary trophoblasts rapidly cease proliferation in vitro impairing genetic manipulation. Hence, trophoblastic cell lines have been widely used as surrogates to study EVT function. Although the cell lines share some molecular marker expression with their primary counterpart, it is unknown to what extent they recapture the invasive phenotype of EVT. Therefore, we here report the first thorough GeneChip analyses of SGHPL-5, HTR-8/SVneo, BeWo, JEG-3 and the novel ACH-3P trophoblast cells in comparison to previously analysed primary villous cytrophoblasts and extravillous trophoblasts.

Description
Human cytotrophoblast organoid cultures were established from the villous trophoblast of first trimester placentas. We analyzed the global expression profile of the cytotrophoblast organoids (CTB-ORG) and compared to the profile of the tissue of origin i.e. villous cytotrophoblast (vCTB) as well as to differentiated syncytiotrophoblast (STB) and placental fibroblasts (FIB). Overall design: We employed QuantSeq method to analyzed the global expression profile of the cytotrophoblast organoids (4 replicates, CTB-ORG 1-4) and compared to the profile of the tissue of origin i.e. villous cytotrophoblast (3 replicates, vCTB 1-3) as well as to in vitro differentiated syncytiotrophoblast (3 replicates, STB1-3) and placental fibroblasts (2 replicates, FIB 1-2).

Description
Cholestasis may cause cholemic nephropathy that can be modelled in common bile duct ligated (CBDL) mice. We aimed to explore the therapeutic efficacy and mechanisms of norursodeoxycholic acid (norUDCA) in cholemic nephropathy. To determine whether norUrsodeoxycholic acid (norUDCA) prevents cholemic nephropathy in long-term CBDL mice, a norUDCA-enriched diet (0.125% w/v, corresponding to 200 mg/kg/day for a mouse of 25 g body weight eating about 4g daily) or a standard mouse diet (Sniff, Soest, Germany) were started 5 days prior to CBDL and were continued until harvesting 3 weeks thereafter. For transcriptional profiling using microarray technology, we compared sham-operated (SOP) mice and 3-week CBDL mice that were either fed 0.125% norUDCA-enriched or standard mouse diets.

Description
The aim of this study was to identify differentially expressed signatures of non-invasive (EGFR+) and invasive (HLA-G+) human trophoblast subtypes. These populations were isolated from single first trimester placentas from 10-12 weeks of gestation. Overall design: We performed RNAseq to analyze the global expression profile of two different trophoblastic subtypes.

Description
Analysis of gene expression over serial 150um sections of a single gestational week 14.5 human neocortical specimen. The hypothesis tested with this dataset was that a transcriptional signature of radial glia (neural stem cells) could be isolated via unsupervised gene coexpression analysis due to variation in the abundance of this cell type from section to section. This dataset is the first of its kind generated using this method (Gene Coexpression Analysis of Serial Sections, or GCASS).

Description
Purpose: To characterize transcriptional changes associated with homozygous inactivation of Dot1l or Mll1 in MN1 driven AML Methods: We sequenced mRNA from murine LSK-cells transformed using forced expression of MN1 (MSCV-MN1-IRES-GFP), and transduced with Cre-vector to inactivate either Dot1l or Mll1. Cells were sorted for Cre-expression (pTomato fluorescent marker) or expression of an inert control vector. Results: Inactivation of either Dot1l or Mll1 in this model leads to a substantial delay or complete abrogation of leukemia development.Loss of Dot1l or Mll1 are associated with gene expression changes that have substantial overlap. In addition, genes that are downregulated follwing inactivation of Dot1l or Mll1 have substantial overlap with the gene set upregulated in MN1 transduced CMPs. Conclusions: MN1 mediated leukemogenesis is associated with a gene expression program that dependes on Mll1 and Dot1l Overall design: Examination of mRNA levels between Dot1l f/f and Dot1l ko, and Mll1 f/f and Mll1 ko.

Description
The initiation of the mucosal immune response in Peyers patch (PP) relies on the sampling, processing and efficient presentation of foreign antigens by dendritic cells (DC). PP DC encompass five subsets, among which CD11b+ conventional DC (cDC) and LysoDC have distinct progenitors and functions but share many cell surface markers. This has previously led to confusion between these two subsets. In addition, another PP DC subset, termed double-negative (DN), remains poorly characterized. Here, we have studied the genetic relatedness of the different subsets of PP cDC at steady state and under TLR7 ligand stimulation. We also provide the transcriptional profiles of subepithelial TIM-4- and interfollicular TIM-4+ macrophages.
