Description
Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness and attacks of muscle atonia triggered by strong emotions (cataplexy). The best biological marker of narcolepsy is orexin deficiency with dramatic loss in hypothalamic orexin-producing neurons. Together with a tight HLA and T-cell receptor alpha(5) association, narcolepsy is believed to be autoimmune although all attempts to prove it have failed.To characterize orexin specific peptides we produced a transgenic mouse model to access to the orexin neurons transcription profile. We generated BAC-based transgenic mice by replacing the orexin coding sequence by a flag-tagged poly(A) binding protein (Pabp1) cDNA sequence. The basis of this construct is to take advantage of the ability of Pabp1 to bind to the poly(A) tails of mRNAs in vivo. Thus mRNAs from orexin cells are expected to be enriched by cross-linking them to the flag-tagged PABP and then co-immunoprecipitating this complex with a specific anti-flag monoclonal antibody.

Illumina HiSeq 2500
Description
Purpose: the goal of this experiment was to identify differentially expressed genes in Six3 null, Six6 null and Six3;Six6 compound null retinas by RNAsequencing. Method: Retinas were dissected out from the following E13.5 mouse embryos: 1) WT (Six3F/F; Six6+/+); 2) Six3 KO (Six3F/F; CAGGCre-ERTM; Six6+/+); 3) Six6 KO (Six3F/F; Six6–/–); 4) DKO (Six3F/F; CAGGCre-ERTM; Six6–/–). RNA was then extracted from the retinas and profiled using RNAsequencing. Results: RNA isolated from three pairs of retinas for each genotype group (181.2-792 ng, RIN>9) was used for library preparation using KAPA RNA HyperPrep Kit with RiboErase. Sequencing was run on Illumina HiSeq 2500 in 100-bp single-end high-output mode in the Einstein Epigenomics Core Facility. About 30 million reads were generated for each sample. Each genotype group initially had three biological replicates, but one Six6 KO replicate was later removed due to over duplication. After trimming adapters with Trim Galore (v. 0.3.7), RNA-Seq reads were aligned back to mouse genome mm10 using Tophat (v. 2.0.13). The number of reads mapped back to each gene was calculated with HTseq (v.0.6.1) using Refseq gene annotation (downloaded from the UCSC genome browser in 03/17). The Cuffdiff in Cufflinks package (v. 2.2.1) was used to generate FPKM values. We identified 13498 transcripts with FPKM value >1 in at least one of samples. Deseq2 was used to determine the differentially expressed genes (DEGs) with FDR less than 0.05 as a cutoff. Overall design: Three pairs of retinas from each genotype were analyzed (n=3 biological replicates). One Six6 KO sample was later removed due to high duplication. Six3KO, Six6KO and DKO samples were compared to WT Controls (Six3F/F) using DESeq2, respectively .

Description
The oral cavity is the persistent reservoir for EBV with lifelong infection of resident epithelial and B cells. Infection of these cell types results in distinct EBV gene expression patterns that are regulated by epigenetic modifications involving DNA methylation and chromatin structure. Such regulation of EBV gene expression relies on viral manipulation of the host epigenetic machinery that may inadvertently result in long-lasting, oncogenic host epigenetic reprogramming. To test this hypothesis in the context of EBV infection of epithelial cells, we established a transient infection model to identify the epigenetic consequences after EBV infection of immortalized normal oral keratinocytes and subsequent viral loss.
