In order to recover nuclei with two active X chromosomes (class I), we developed a reprogramming strategy by supplementing hESC media with the small molecules sodium butyrate, and 3-deazaneplanocin A (DZNep). In order to determine how B+D affects global gene expression, we performed microarray analysis in triplicate in the HSF-6 (8) C and HSF-6 (8) B+D treated cultures. We also evaluated HSF-6 (S9) B+D in triplicate and identified no statistically significant changes in gene expression in HSF-6 (S9) B+D compared to HSF-6 (8) B+D treated cultures. This suggests that global transcriptional differences are more strongly modulated by presence or absence of B+D and not the percentage of class I, II or III nuclei.

View SamplesThere is an association between transcriptome and the exercise-related phenotype. Peripheral blood cells suffer alterations in the gene expression pattern in response to perturbations caused by exercise. The acute response to endurance activates stress and inflammation, as well as growth and tissue repair responses.
PBMCs express a transcriptome signature predictor of oxygen uptake responsiveness to endurance exercise training in men.

View SamplesAim: Transcriptional analysis of the duodenum of adult Nkx2.2flox/SD;Villin-Cre (SDint) mice versus control Methods: 2 cm of the duodenum (as measured from the stomach) of 6 week old control and mutant mice were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: 206 genes with a p-value <0.05 were significantly changed. Among these are some enteroendocrine hormones. Conclusion: The SD domain of Nkx2.2 regulates specification of some enteroendocrine cells Overall design: mRNA profiles of the duodenum of 6 week old control and SDint mice were generated by deep sequencing, in triplicate, using Illumina HiSeq2000.

View SamplesAim: Transcriptional analysis of the colon of adult Nkx2.2flox/flox;Villin-Cre (Nkx2.2int) mice versus control Methods: 2 cm of the colon (as measured after the caecum) of 6 week old control and mutant mice were dissected and total RNA extracted. Libraries were prepared from total RNA (RIN>8) with the TruSeq RNA prep kit (Illumina) and sequenced using the HiSeq2000 (Illumina) instrument. More than 20 million reads were mapped to the mouse genome (UCSC/mm9) using Tophat (version 2.0.4) with 4 mismatches and 10 maximum multiple hits. Significantly differentially expressed genes were calculated using DEseq. Results: 53 genes with a p-value <0.05 were down-regulated and 36 were up-regulated. Among the changed genes are enteroendocrine hormones. Conclusion: Nkx2.2 regulates enteroendocrine cell specification Overall design: mRNA profiles of the colon of 6 week old control and Nkx2.2int mice were generated by deep sequencing, using Illumina HiSeq2000.

View SamplesWe used RNA sequencing to study gene expression in lymph node derived DCs from anaphylactic mice sensitized intranasally with the major peach allergen Pru p 3, during the acute reaction phase, induced intraperitoneally. In total, 237 genes changed significantly, 181 showing at least two-fold changes. Almost three quarters of these increased during anaphylaxis Overall design: 5 Female Balb/c mice aged 4-5 weeks, were sensitized to peach using intranasally administered Pru p 3 in combination with LPS and challenged intraperitoneally as described previously . 5 Littermates, treated with intranasally administered PBS (instead of Pru p 3 and LPS), and later given an intraperitoneal challenge as per the anaphylactic mice, were used for comparison.

Defective decidualization during and after severe preeclampsia reveals a possible maternal contribution to the etiology.

View SamplesIn preeclampsia (PE), cytotrophoblast (CTB) invasion of the uterus and spiral arteries is often shallow. Thus, the placentas role has been a focus. We hypothesized that decidual defects are an important determinant of the placental phenotype. We isolated (human) endometrial stromal cells (hESCs) from non-pregnant donors with a prior pregnancy that was complicated by severe PE (sPE). Versus controls, they failed to decidualize as demonstrated by morphological criteria and the analysis of stage-specific antigens. These results were bolstered by showing that they were transcriptionally inert. Additionally, we used laser microdissection to isolate the decidua from tissue sections of the maternal-fetal interface. Transcriptional profiling revealed sPE-associated defects in gene expression. Also, decidual cells from sPE patients, which de-differentiated in vitro, failed to re-decidualize in culture. Immediately following isolation they released factors that inhibited CTB invasion, linking a possible cause to a known effect. These data suggested that failed decidualization is an important contributor to down regulated CTB invasion in sPE. Diagnosis of this defect prior to pregnancy would enable therapies that are designed to improve decidualization, a novel strategy for prevention.
