Description
We discovered a rare missense mutation in NR1H4 (R436H), which encodes the farnesoid X receptor (FXR), associating with lower levels of total cholesterol in the Icelandic population. To explore the effects of R436H we used CRISPR-Cas9 to generate homozygous NR1H4 R436H and NR1H4 knockout human iPSC lines which we differentiated to hepatocytes. Hepatocytes were treated with an FXR agonist for 24 hours and transcript abundance measured by RNA-seq. The global response to FXR activation in NR1H4 R436H cells was very similar to that of wild-type cells showing that it is not a loss-of-function mutation. However, we did observe subtle gene expression differences compatible with an effect on lipids when we compared R436H agonist treated hepatocytes to wild-type agonist treated hepatocytes. Overall design: RNA-seq was performed on wild-type, NR1H4 knockout and NR1H4 R436H iPSC-derived hepatocytes treated with FXR agonist GW4064.

Description
Maternal Blood histamine levels are tightly controlled in normal pregnancy. However, in specific complications of human pregnancy such as pre-eclampsia the levels of both placental and maternal blood histamine increase. Increasing blood histamine levels nonetheless, have been associated with oxidative stress, endothelial dysfunction, abnormal tissue growth, and Th1/TH2 imbalance, which are also linked to pre-eclampsia. Little is known of the molecular responses in the placenta to the prolonged exposure to increasing histamine levels in the presence of changing oxygen concentrations.

Description
Classical dendritic cells (DCs) are key players at the interface between innate and adaptive immunity. In the kidney exist 2 major subsets of cDCs: CD11b+ cDCs and CD103+ cDCs. We investigated their function in the most widely used model of experimental glomerulonephritis (GN) in mice: nephrotoxic nephritis (NTN). Consistent with a role for cDCs in nephrotoxic nephritis, depletion of ZBTB46+ cells (all cDCs) attenuated kidney injury, while deficiency of the CD103+ subset of cDCs accelerated injury via a mechanism that involved increased neutrophils. This RNAseq was performed to analyze transcriptional changes in FACS-sorted renal CD11b+ and CD103+ cDCs under healthy conditions and at day 7 of NTN to reveal why both subsets have different functions in GN. Overall design: The study was performed with total of 6 mice (wildtype, male, age 8-12 weeks). 3 mice were sacrificed in the healthy situation, 3 mice were sacrificed 7 days after injection of the nephrotoxic nephritis antiserum (NTN). From each mouse CD11b+ and CD103+ DCs were sorted, resulting in 4 experimental conditions with 3 biological replicates each: CD103_healthy, CD11b_healthy, CD103_NTN, CD11b_NTN.

Description
Analysis of the gene expression pattern in the caput, corpus and cauda epididymides of three donors of 26-50 years of age with no medical pathologies that could affect reproductive function. The data generated in this study demonstrate a region specific gene expression pattern along the human epididymis that seems to coincide with the morphological distinctive features of the excurrent duct.

Description
We previously demonstrated that Alox5deficiency impairs the function of LSCs and prevents the initiation of BCR-ABL-induced CML. To identify the pathways in whichAlox5gene regulates function of LSCs, we performed a comparative DNA microarray analysis using total RNA isolated from non-BCR-ABL-expressing Lin-Sca-1+c-Kit+, BCR-ABL-expressing wild type LSCs and BCR-ABL-expressing Alox5-/- LSCs. The result was validated by quantitative real-time PCR analysis of non-BCR-ABL-expressing Lin-Sca-1+c-Kit+, BCR-ABL-expressing wild type LSCs and BCR-ABL-expressing Alox5-/- LSCs.

Description
Adipocytes arise from commitment and differentiation of adipose precursors in white adipose tissue (WAT). In studying adipogenesis, precursor markers, including Pref-1 and PDGFRa, are used to isolate precursors from stromal vascular fraction of WAT, but the relationship among the markers is not known. Here, we used Pref-1 promoter-rtTA system in mice for labeling Pref-1+ cells and for inducible inactivation of Pref-1 target, Sox9. We show requirement of Sox9 for maintenance of Pref-1+ proliferative, early precursors. Upon Sox9 inactivation, these Pref-1+ cells become PDGFRa+ cells that express early adipogenic markers. Thus, we show for the first time that Pref-1+ cells precede PDGFRa+ cells in the adipogenic pathway and that Sox9 inactivation is required for WAT growth and expansion. Furthermore, we show that, in maintaining early adipose precursors, Sox9 activates Meis1 which prevents adipogenic differentiation. Our study also demonstrates the Pref-1 promoter-rtTA system for inducible gene inactivation in early adipose precursor population. Overall design: RNA-Sequencing for differentially expressed genes (more than 2-fold) between GFP+ (Pref-1+) ingWAT SVF cells from floxed and Sox9 PreASKO mice (n=6 pooled).

Description
Worldwide, almost 100 millions men rely on vasectomy for male contraceptive purposes. Due to changes in their personal life, an increasing number of these men request surgical vasectomy reversal. Unfortunately, a significant proportion of these men remain infertile, despite the reestablishment of patent ducts, possibly due to epididymal damages caused by vasectomy. In animal models, vasectomy affects different epididymal physiological and biochemical parameters. However, consequences of vasectomy on these biochemical parameters are poorly understood at the molecular level. Furthermore, results obtained with animal models cannot by extrapolated to human to understand the consequences of vasectomy on epididymal functions. Gene expression pattern of epididimydis is highly regulated. We previously showed that the human epididymal expression pattern of two genes is altered under vasectomy. To complete the list of epididymal genes affected by vasectomy, we analysed the epididymal gene expression profile of three vasectomised donors, using the affymetrix human GeneChip U133 Plus 2. These results were compared with gene expression pattern of three normal donors. The data generated allowed the identification of many human epididymal genes for which the expression is modified under vasectomy. Qt-PCR and western-blot analysis of six selected genes known to be expressed in specific epididymal segments were performed. The Qt-PCR results confirmed the selected transcripts expression pattern deduced from microarrays data, while the western-blot analysis revealed some differences in protein distribution along the epididymis when compared to the transcripts expression pattern. These results contribute to the understanding of the causes of the persistent of infertility even though spermogram values suggest surgical success of vasovasostomy.
