Description
Coupling immunity and development is essential to ensure survival despite changing internal conditions in the organism. The metamorphosis of the fruit fly represents a striking example of drastic and systemic physiological changes that need to be integrated with the innate immune system. However, the mechanisms that coordinate development and immune cell activity in the transition from larva to adult in Drosophila remain to elucidate. The steroid hormone ecdysone is known to act as a key coordinator of metamorphosis. This hormone activates a nuclear receptor, the Ecdysone Receptor (EcR), which acts as a heterodimer with its partner Ultraspiracle (USP). Together, they activate the transcription of primary response genes, which in turn activate the transcription of a battery of late response genes. We have revealed that regulation of macrophage-like cells (hemocytes) by the steroid hormone ecdysone is essential for an effective innate immune response over metamorphosis. We have shown that in response to ecdysone signalling, hemocytes rapidly up regulate actin dynamics, motility and phagocytosis of apoptotic corpses, and acquire the ability to chemotax to damaged epithelia. Most importantly, individuals lacking ecdysone-activated hemocytes are defective in bacterial phagocytosis and are fatally susceptible to infection by bacteria ingested at larval stages, despite the normal systemic production of antimicrobial peptides. This decrease in survival is comparable to the one observed in pupae lacking immune cells altogether, indicating that ecdysone-regulation is essential to hemocyte immune functions and survival after infection.

Illumina HiSeq 2000
Description
Aim: 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.

Aim: 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.

Description
We have performed a genome-wide analysis of common genetic variation controlling differential expression of transcript isoforms in the CEU HapMap population using a comprehensive exon tiling microarray covering 17,897 genes. We detected 324 genes with significant associations between flanking SNPs and transcript levels. Of these, 39% reflected changes in whole gene expression and 55% reflected transcript isoform changes such as splicing variants (exon skipping, alternate splice site usage, intron retention), differential 5 UTR (initiation of transcription) usage, and differential 3 UTR (alternative polyadenylation) usage.

Description
A subpopulation of pericytes expressing the Glast-CreERT2 transgene (Type A pericytes) has recently been identified as the main source of stromal scar tissue that forms after SCI. Identification of molecules associated with pericyte-derived scarring may offer new therapeutic targets to facilitate axon regeneration following central nervous system (CNS) injury. We conducted genome-wide RNA sequencing of (i) uninjured spinal cord segments and (ii) lesion sites presenting full or attenuated pericyte-derived scarring 14 days after SCI. Overall design: Adult Glast-Rasless-YFP (Glast-CreERT2 x R26R-YFP x Rasless) mice receiving vehicle (Veh) or tamoxifen (Tam) underwent dorsal hemisection at high thoracic level. Fourteen days after SCI, injury sites were dissected out, homogenized and total RNA was isolated from lesions presenting (i) dense (Veh, n=4) and (ii) attenuated (Tam, n=4) pericyte-derived scarring. Age-matched Glast-Rasless-YFP mice served as uninjured controls (n=4).
