Illumina HiSeq 2500
Description
Total RNA-sequencing on 150-200 ICOS+CD38+ cTfh cells per person prior to vaccination (day 0), and seven (day 63) and 28 (day 84) days after the third vaccination. Overall design: Blood samples were taken from healthy volunteers taking part in a Phase 1b clinical trial. mRNA was isolated from flow sorted circulating Tfh cells (CD4+CD45RA-CXCR5+PD1+ICOS+CD38+ cells) and RNA-sequencing performed on cTfh from days 0, 7 and 28 reletive to vaccination

Description
Total mRNA-sequencing on memory T helper cell populations from human blood and lymph nodes. Overall design: Paired blood and lymph node samples were taken from patients recruited from the renal transplant live donor program at Cambridge University Hospitals NHS Foundation Trust, and who provided informed consent. All patients were either receiving or within 6 months of requiring renal replacement therapy. Patients taking immunosuppressive medication prior to transplant were excluded. mRNA was isolated from flow sorted CD4+ T cell populations and RNA-sequencing performed.

Affymetrix Zebrafish Genome Array (zebrafish)
Description
The B1 SOX transcription factors SOX1/2/3/19 have been implicated in various processes of early embryogenesis. However, their regulatory functions in stages from the blastula to early neurula remain largely unknown, primarily because loss-of-function studies have not been informative to date. In our present study, we systematically knocked down the B1 sox genes in zebrafish. Only the quadruple knockdown of the four B1 sox genes sox2/3/19a/19b, which are active in the early embryo, resulted in very severe developmental abnormalities, confirming that the B1 sox genes are functionally redundant. We characterized the sox2/3/19a/19b quadruple knockdown embryos in detail by examining the changes in gene expression through microarray analysis as well as in situ hybridization.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The placenta serves as the structural interface for nutrient and waste exchange for proper fetal development. Although defects in placental function result in various placental disorders, molecular mechanisms orchestrating placental development and function are poorly understood. Gene targeting studies have shown that Hgf or c-Met KO embryos exhibit growth retardation and markedly smaller size of the placenta, and die by E14.5. Stem/progenitor cells in various tissues express c-Met and they participate in morphogenesis and tissue repair. Thus, we hypothesized that the HGF/c-Met signaling pathway is essential for the emergence, proliferation, and/or differentiation of putative stem/precursor cells of labyrinth trophoblasts at the midgestation stage.

- Affymetrix Rice Genome Array (rice)
Description
Cytokinins (CKs) are a class of plant hormones that regulate many aspects of growth and development, including cell division, apical dominance, leaf senescence, nutrient signaling, and shoot differentiation. In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. Although cytokinin plays an important role for growth and development in the Gramineae, our knowledge of cytokinin responsive genes in monocotyledonous species is very limited compared to Arabidopsis. The search for genes whose expression is modified by CK has yielded a number of valuable tools that have been used to understand CK signaling and the complex developmental processes under control of this hormone. We tried to identify rice genes regulated by CK using an Affymetrix rice genome array.

Description
Cytokinins (CKs) are a class of plant hormones that regulate many aspects of growth and development, including cell division, apical dominance, leaf senescence, nutrient signaling, and shoot differentiation. In the past decade, substantial progress has been made in understanding CK biosynthesis, metabolism and signal transduction. Much of this knowledge is based on research in Arabidopsis, a dicotyledonous model plant. The current model of the CK signaling pathway is a multi-step His-Asp phosphorelay system. Some of the cytokinin-inducible response regulators are thought to act as negative regulators of CK signaling. We tried to identify rice genes regulated by CK-inducible response regulator using an Affymetrix rice genome array and transgenic rice that over-express OsRR6.

Description
Objective: Amniotic fluid (AF) is a proximal fluid to the fetus containing higher amounts of cell-free fetal RNA/DNA than maternal serum, thereby making it a promising source for novel biomarker discovery of fetal development and maturation. Our aim was to compare AF transcriptomic profiles at different time points in pregnancy to demonstrate unique genetic signatures that would serve as potential biomarkers indicative of fetal maturation. Methods: We isolated AF RNA from 16 women at different time points in pregnancy: 4 from 18-24 weeks, 6 from 34-36 weeks, and 6 from at 39-40 weeks. RNA-sequencing was performed on cell-free RNA. Gene expression and splicing analyses were performed in conjunction with cell-type and pathway inference. Results: Sample-level analysis at different time points in pregnancy yielded a strong correlation with cell types found in the intrauterine environment and fetal respiratory, digestive and external barrier tissues of the fetus, using high-confidence cellular molecular markers. While some genes and splice variants were present throughout pregnancy, an abundant number of transcripts were uniquely expressed at different time points in pregnancy and associated with distinct fetal co-morbidities (respiratory distress and gavage feeding), indicating fetal immaturity. Conclusions: The AF transcriptome exhibits unique cell- and organ-selective expression patterns at different time points in pregnancy that can potentially identify fetal organ maturity and predict neonatal morbidity. Developing novel biomarkers indicative of the maturation of multiple organ systems can improve upon our current methods of fetal maturity testing which focus solely on the lung, and better inform obstetrical decisions regarding delivery timing. Overall design: RNA-Seq from cell-free was used to idenitfy mRNA transcripts indicative of overall fetal maturity.
