Illumina HiSeq 2500
Description
The objective of this study was to examine the effect of the presence of a single or multiple embryo(s) on the transcriptome of the bovine oviduct. In Experiment 1, cyclic (non-bred, n = 6) and pregnant (artificially inseminated, n = 11) heifers were slaughtered on Day 3 after estrus, and the ampulla and isthmic regions of the oviduct ipsilateral to the corpus luteum were separately flushed. Oviductal epithelial cells from the isthmus region, in which all oocytes/embryos were located, were snap-frozen for microarray analysis. In Experiment 2, heifers were divided into cyclic (non-bred, n = 6) or pregnant (multiple embryo transfer, n = 10) groups. In vitro-produced presumptive zygotes were transferred endoscopically to the ipsilateral oviduct on Day 1.5 post estrus (n = 50 zygotes per heifer). Heifers were slaughtered on Day 3 and oviductal isthmus epithelial cells were recovered for RNA sequencing. Microarray analysis in Experiment 1 failed to detect any difference in the transcriptome of the oviductal isthmus induced by the presence of a single embryo. In Experiment 2, following multiple embryo transfer, RNA sequencing revealed 278 differentially expressed genes of which 123 were up- and 155 were down-regulated in pregnant heifers. Most of the down-regulated genes were related to immune function. Overall design: Transcriptional profiles of oviductal isthmus epithelial cells from cyclic and pregnant heifers were generated by sequencing of total RNA on the Illumina HiSeq 2500 platform

- Affymetrix Bovine Genome Array (bovine)
Description
The oviduct is a specialized organ playing crucial roles in the success of early reproductive events and it provides an optimal microenvironment for early embryonic development. However, changes in oviductal environment due to estrus synchronization and superovulation hormonal treatments and subsequent influence on embryos transcriptome profile are not yet investigated. For that, the objective of this study was to investigate differences in developmental rate and transcriptome profile of bovine blastocysts cultured under superovulation or synchronization oviductal environment.

Description
The FBXL10 protein (also known as KDM2B, JHDM1B, CXXC2, and NDY1) is bound to essentially all CpG-rich promoters in the mammalian genome. FBXL10 is expressed as two isoforms: FBXL10-1, a longer form that contains an N-terminal JmjC domain with C- terminal F-box, CXXC, PHD, RING, and leucine rich repeat (LRR) domains, and FBXL10-2, a shorter form that initiates at an alternative internal exon and which lacks the JmjC domain but retains the other domains. Selective deletion of Fbxl10-1 had been reported to produce a minor and variable phenotype, and most mutant animals were essentially normal. We show here that deletion of Fbxl10-2 (in a manner that does not perturb expression of Fbxl10-1) resulted in a very different phenotype with craniofacial abnormalities, greatly increased lethality, and female sterility in surviving homozygous mutants. The phenotype of the Fbxl10-2 deletion was more severe in female mutants. We found that mutants that lacked both FBXL10-1 and -2 showed embryonic lethality and even more extreme sexual dimorphism, with more severe gene dysregulation in mutant female embryos. X-linked genes were most severely dysregulated, and there was marked overexpression of Xist in mutant females although genes that encode factors that bind to Xist RNA were globally down-regulated in mutant female as compared to male embryos. FBXL10 is the first factor shown to be required both for the normal expression and function of the Xist gene. Overall design: Expression analysis using RNA-seq was performed on WT and Fbxl10T/T male and female embryos.

Description
Overexpression of high mobility group AT-hook 2 (HMGA2) associated with truncations of its 3 untranslated region (UTR) with let-7 micro RNA-complementary sequences have been identified in patients with paroxysmal nocturnal hemoglobinuria (PNH). Here, we generated transgenic mice (Hmga2 mice) with a 3UTR-trncated Hmga2 cDNA that overexpress Hmga2 mRNA and protein in hematopoietic organs. Hmga2 mice showed proliferative hematopoiesis that mimicked a myeloproliferative neoplasm (MPN)-like phenotype with increased numbers of all lineages of peripheral blood cells, hypercellular bone marrow (BM), splenomegaly with extramedullary erythropoiesis, and erythropoietin-independent erythroid colony formation compared to wild-type mice. Hmga2 BM-derived cells took over most of hematopoiesis in competitive repopulations during serial BM transplants. When we bred mice with circulating PNH cells (Piga- mice) with Hmga2 mice, the lack of GPI-linked proteins did not add an additional clonal advantage to the Hmga2+ cells. In summary, our results showed that the overexpression of a 3UTR-truncated Hmga2 leads to a proliferative hematopoiesis with clonal advantage, which may explain clonal expansion in PNH or MPN at the level of HSC.
