Project description:3 samples of R1, R2 and R3 bone marrow monocytes were compared from 3 biological replicates in 3 separate experiments. R1, R2 and R3 were sorted from triplicate experiments from pools of mice
Project description:Investigation of whole genome transcription expression level changes in Drosophila mojavensis wild-type populations (1 Punta Onah: PO, 2 Organ Pipe National Monument: OPNM, 3 Punta Prieta:PP, and 4 San Quintin: SQ). The experiment was designed to investigate functional genomic responses to temperature variation (15, 25, and 35 °C) in adult Drosophila mojavensis wild populations. For each treatment 1-5 replicates were used (R1, R2, R3, R4 & R5). SO and BC represents Sonora deserts and Baja California region respectively.
Project description:We reconstituted arrays of CTCF binding sites (L1, L2, L3, L4, R1, R2 and R3) and devised a synthetic topological insulator with tetO for chromatin-engineering (STITCH). By coupling STITCH with tetR linked to the KRAB domain to induce heterochromatin and disable the insulation, we developed a drug-inducible system to control gene activation by enhancers. We inserted STITCH into five different positions of the remaining allele of the locus: \\"STITCH+30kb\\", \\"STITCH+440kb\\", \\"STITCH+1760kb\\" and \\"STITCH+1790kb\\" have the STITCH insertions away from the MYC promoter for the indicated distances to the telomeric side of the p arm of the chromosome. \\"STITCH-30kb\\", at the 30-kb upstream from the MYC. We also made a deletion clone of the enhancer region, termed del(30-440). We made deletion of each CTCF array, L (delL) and R (delR), inversion of R (invR), deletion of the middle five binding sites from L2 to R2 (del(L2-R2)), and deletion of the six sites but for R3 (del(L1-R2)) in STITCH+30kb. We also obtained deletion and inversion of the whole of STITCH (del(L1-R3) and inv(L1-R3)). We integrated a transgene consisting of tetR-KRAB followed by DNA encoding the 2A peptide and the puromycin resistant gene with piggyBac transposition into the genome in the STITCH+30kb clone (STITCH/KRAB). We performed 4C-seq (Circular chromatin conformation capture assay followed by deep-sequencing) from the MYC promoter as a viewpoint to see how STITCH impacts on the chromatin conformation.

The experiment was designed to investigate functional genomic responses to temperature variation (15, 25, and 35 °C) in adult Drosophila mojavensis wild populations. For each treatment 1-5 replicates were used (R1, R2, R3, R4 & R5). SO and BC represents Sonora deserts and Baja California region respectively. A total of 97 hybridizations were performed in this entire experiment. We used 135K 12-plex NimbleGen arrays. Total RNA was recovered from each sample listed below. The experimental design consisted a total of four populations (Punta Onah:PO; Organ Pipe National Manument:OPNM, Punta Prieta:PP and San Quintin:SQ), two host diets (Agria:AG and Organ pipe:OP) and three temperature treatments (15, 25 and 35 °C). Each chip measures the expression level of 14528 transcripts. One to 5 replicates were used for each type (R1, R2, R3, R4 and R5). Fly source details are as follows: Punta Onah 2007:PO07; Organ Pipe National Monument 2008:OPNM08; Punta Prieta 2008:PP08; San Quintin 2008:SQ08.
