Project description:We examined the ATAC-seq chromatin profiles of epidermis from newborn CRISPR-edited mice that have the 923 enhancer located within the Epidermial Differentiation Complex deleted. We examined two independent deletion lines, 923del and 923large, homozygous mutants, as well as wild type mice. We find overall there are not many differences in chromatin accessibility upon the loss of the 923 enhancer, though there are a few peaks of less accessible DNA within the EDC and more accessible DNA just outside the EDC.
Project description:We examined the RNA expression profiles of whole skin from newborn CRISPR-edited mice that have the 923 enhancer located within the Epidermial Differentiation Complex deleted. We examined two independent deletion lines, 923del and 923large, both homozygous mutants and heterozygotes, as well as wild type mice and involucrin Ivl knockout mice. We find that Ivl, the gene most proximal to 923, is downregulated upon the loss of the enhancer in both independent deletions, and 4 additional genes are also downregulated in both deletion lines, a secondary effect of the loss of Ivl, as concluded by comparing to the Ivl KO mice. We thus conclude that Ivl is the primary target gene of the 923 enhancer and establish a 923-Ivl regulatory module.
Project description:Comparison between pattern of gene expression in uncultured keratinocytes derived from the epidermis of embryonic mice (E15.5) versus newborn mice and comparison between pattern of gene expression in primary keratinocytes derived from newborn mice plus/minus activated Notch1 expression. Keywords = mouse Keywords = keratinocyte Keywords = skin Keywords = embryonic development. Keywords: other
Project description:We analyzed Brg1 binding genomeiwide in freshly isolated newborn mouse epidermal keratinocytes using ChIP-seq technology Mouse epidermal keratinocytes were isolated form the newborn C57Bl6 mice and Brg1 binding in their chromatin was analyzed using ChIP-seq technology on Hi-Seq 2500 machine
Project description:Gene expression in wild-type and p38a-knockout keratinocytes were compared. Keratinocytes were isolated from newborn mice, and left unirradiated (0 h) and irradiated (4 h) with ultraviolet-B (UVB). C57BL/6 wild-type mice, and keratinocyte-specific p38a-knockout mice on a C57BL/6 background were used for isolation of primary keratinocytes.
