Description
We sequenced liver mRNA from 23 individual pigs (5 prefed and 18 fasted) taken at 4 separate time points to evaluate the change in gene expression over the course of hemorrhagic shock and resuscitation in response to a carbohydrate prefed state. Overall design: Examination of mRNA levels in liver biopsies from pigs at 4 timepoints throughout hemorrhagic shock and resuscitation
Publication Title
Fed state prior to hemorrhagic shock and polytrauma in a porcine model results in altered liver transcriptomic response.

Affymetrix E. coli Genome 2.0 Array (ecoli2)
Description
Bacteria selectively consume some carbon sources over others through a regulatory mechanism termed catabolite repression. Here, we show that the base pairing RNA Spot 42 plays a broad role in catabolite repression in Escherichia coli by directly repressing genes involved in central and secondary metabolism, redox balancing, and the consumption of diverse non-preferred carbon sources. Many of the genes repressed by Spot 42 are transcriptionally activated by the global regulator CRP. Since CRP represses Spot 42, these regulators participate in a specific regulatory circuit called a multi-output feedforward loop. We found that this loop can reduce leaky expression of target genes in the presence of glucose and can maintain repression of target genes under changing nutrient conditions. Our results suggest that base pairing RNAs in feedforward loops can help shape the steady-state levels and dynamics of gene expression.

Description
Lymphocytic Choriomeningitis Virus (LCMV) specific CD8+ T cells (P14) were transferred into congenic WT mice followed by LCMV(DOCILE) infection. CXCR5-expressing (CXCR5+) or CXCR5 non-expressing (CXCR5-) P14 were purified on day 8 after infection, and total mRNA were sequenced from these populations. mRNA of P14 from uninfected mice (Naive P14) was also sequenced. Overall design: Examination of mRNA level in CXCR5 expressing P14 (CXCR5+P14) and non-expressing P14 (CXCR5-P14) from LCMV infected mice day 8 post infection. mRNA of P14 from uninfected mice (Naïve P14) was also examined.

Description
To understand the basic biological property of hair cells (HCs) from lower vertebrates, we examined transcriptomes of adult zebrafish HCs. GFP-labeled HCs were isolated from the utricle, saccule, and lagena, the three inner-ear sensory epithelia of a pou4f3 promoter-driven GAP-GFP line of transgenic zebrafish. 2,000 HCs and 2,000 non-sensory cells from the inner ear were individually collected by suction pipet technique. RNA sequencing was performed and the resulting sequences were mapped, analyzed, and compared. Comparisons allow us to identify enriched genes in HCs, which may underlie HC specialization. Overall design: Examination of transcriptomes of adult zebrafish inner ear hair cells and surrounding cells individually collected and sorted using pou4f3 promoter-driven GFP marking hair cells.

- Zebrafish Gene 1.0 ST Array (zebgene10st)
Description
We have characterised the zebrafish ortholog, setb, and investigated its role in embryogenesis. Phylogenetic analysis showed that zebrafish Setb has an amino acid sequence identity of approximately 96% with the mammalian orthologs. Whole mount immunofluorescence analysis revealed that Setb is expressed mainly in the eye, the lateral line neuromasts and the olfactory pit. Knockdown of setb using antisense morpholino oligonucleotides resulted in increased apoptosis, reduced cell proliferation and severe morphological defects. The morphant phenotypes were partially rescued when setb MO1 was co-injected with human set mRNA. In vivo labelling of hair cells in the lateral line of setb morphants with the vital fluorescent dye FM1-43 showed a significant decreased number of functional neuromasts. Gene expression analysis of setb morphants, employing DNA microarrays revealed a role of Setb in neurogenesis and the mechanosensory lateral line system.
