Description
We provide data from several targeted deletions of transcriptional enhancer clusters within mouse F1 embryonic stem (ES) cells. We targeted these regions for deletion with CRISPR/Cas9 genome editing tools. We demonstrate through heterozygous enhancer cluster deletion and allele specific RNA-seq that enhancer clusters differ in their regulatory activity as the magnitude of the observed change in transcription upon enhancer cluster deletion varies greatly. Overall design: Strand specific RNA-seq after heterozygous or homozygous enhancer cluster deletion in mouse F1 ES cells (M. musculus129 x M. castaneus)

Description
To identify proteins regulated by glucose through changes in their rate of protein synthesis, translational profiling of MIN6 cells acutely incubated at either low or high glucose concentration was performed (i.e. microarray analysis was performed on mRNAs associated with polysomes, as an increase in the association of mRNA with polysomes is indicative of an increase in the rate of initiation step of translation and hence an increase in protein expression) (Johannes et al., 1999; Mikulits et al., 2000).

Description
Infertility in lactating dairy cows is explained partially by the metabolic state associated with high milk production. The hypothesis was that lactating and non-lactating cows would differ in endometrial and placental transcriptomes during early pregnancy (day 28 to 42) and this difference would explain the predisposition for lactating cows to have embryonic loss at that time. Cows were either milked or not milked after calving. Reproductive [endometrium (caruncular and intercarunclar) and placenta] and liver tissues were collected on day 28, 35, and 42 of pregnancy. The primary hypothesis was rejected because no effect of lactation on mRNA abundance within reproductive tissues was found. Large differences within liver demonstrated the utility of the model to test an effect of lactation on tissue gene expression. Major changes in gene expression in reproductive tissues across time were found. Greater activation of the transcriptome for the recruitment and activation of macrophages was found in the endometrium and placenta. Changes in glucose metabolism between day 28 and 42 included greater mRNA abundance of rate-limiting genes for gluconeogenesis in intercaruncular endometrium and evidence for the establishment of aerobic glycolysis (Warburg effect) in the placenta. Temporal changes were predicted to be controlled by CSF1, PDGFB, and JUN. Production of nitric oxide and reactive oxygen species by macrophages was a mechanism to promote angiogenesis in the endometrium. Reported differences in pregnancy development for lactating versus non-lactating cows could be explained by systemic glucose availability to the conceptus and appear to be independent of the endometrial and placental transcriptomes.
Publication Title
The transcriptome of the endometrium and placenta is associated with pregnancy development but not lactation status in dairy cows.

Description
The goal of this study was to identify potential AMH-induced genes and regulatory networks controlling regression by RNA-Seq transcriptome analysis of differences in Müllerian Duct mesenchyme between males (AMH signaling on) and females (AMH signaling off) in purified fetal Müllerian Duct mesenchymal cells. This analysis found 82 genes up-regulated in males during MD regression and identified Osterix (Osx)/Sp7, a key transcriptional regulator of osteoblast differentiation and bone formation, as a novel downstream effector of AMH signaling during MD regression. Overall design: Müllerian Duct mesenchymal cells mRNA profiles from 2-7 embryonic day 14.5 embryos were generated by deep sequencing, in triplicate, using Illumina HiSeq 2000.

Description
Homeostatic hematopoietice stem cells (HSCs) with greater divisional history lose repopulating potential after very few cell divisions. Divisional history overrides both phenotype and immediate quiescence in determining functional activity. In GFP label retaining system GFP is progressively diluted when cells proceed through a cascade of divisions.

Description
Human embryonic stem cells (hESCs) replicate by the process of self-renewal, whilst maintaining their pluripotency. Understanding the pathways involved in the regulation of this self-renewal process will assist in developing fully-defined conditions for the proliferation of hESCS required for therapeutic applications. We previously demonstrated a role for Sphingosine-1-phosphate (S1P) in the survival and proliferation of hESCs. The present study investigates further key signalling pathways and the downstream targets of S1P.

Sphingosine-1-phosphate mediates transcriptional regulation of key targets associated with survival, proliferation, and pluripotency in human embryonic stem cells.

Description
Across life neural stem cells (NSCs) generate new neurons in the mammalian brain through asymmetric neurogenic and self-renewing cell divisions. However, the cellular mechanisms underlying NSC asymmetry remain unknown. Using fluorescence loss in photobleaching (FLIP) we here show that NSCs in vitro and within the developing forebrain generate a lateral diffusion barrier during cell division resulting in asymmetric segregation of cellular components. The strength of the diffusion barrier is dynamically regulated with age and depends on the proper function of lamin-associated nuclear envelope constituents. Strikingly, age-associated or experimental impairment of the diffusion barrier disrupts asymmetric segregation of damaged proteins, a product of aging. Thus, the data presented here identify a mechanism how age is asymmetrically distributed during somatic stem cell division.
