Project description:We use ChIP-seq targeting histone 3 lysine 27-acetylation (H3K27ac) to identify putative enhancer sites genome-wide in the ventral pallidum cortex of adult prairie voles
Project description:To investigate the genome-wide DNA binding of chicken p53, we overexpressed chicken p53 with a flag in LMH cells. We then performed genome-wide DNA binding analysis using data obtained from ChIP-seq of LMH cells.
Project description:We use ChIP-seq targeting histone 3 lysine 4 mono-methylation (H3K4me1) to identify putative enhancer sites genome-wide, in the retrosplenial cortex of adult prairie vole males. ChIP samples were generated by targeting a known enhancer mark (H3K4me1) in chromatin extracted from the retrosplenial cortex of 8 males. Illumina libraries were prepared from ChIP and INPUT DNA and sequenced on Illimuna HiSeq 2500 platform.
Project description:Dongxiang blue-shelled chicken, an indigenous chicken breed in China, has segregated significantly for the dermal hyperpigmentation phenotype. Two lines of the chicken have been divergently selected with respect to comb color for over 20 generations. The recent selection has also resulted in a significant difference in egg production. The red comb line (RCL) chicken produces significantly higher number of eggs than that by the dark comb line (DCL) chicken. The objective of this study was to explore potential mechanisms involved in the relationship between comb color and egg production among chickens. We performed genome-wide association study to identify candidate genes associated with chicken comb color using SNP array data, and we conducted selective sweep analysis to identify putative regions of selection harboring pleiotropic genes affecting both comb color and egg production.
Project description:We generated ATAC-seq data for pre- and post-extraction venom gland samples and H3K4me3, H3K27ac, and CTCF ChIP-seq from post-extraction venom gland samples from the Prairie Rattlesnake to investigate patterns of chromatin accessibility, transcription factor binding, and insulation during venom production, and to identify open promoters and active enhancer regions.
