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: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:The study aims to identify genes associated with oxacilin resistance. Staphylococcus aureus USA300 (also referred as 923) is used as reference strain through the whole study.

Project description:We provide data from several targeted deletions of transcriptional enhancer clusters within mouse F1 embryonic stem (ES) cells. We targeted these regions for deletion with CRISPR/Cas9 genome editing tools. We demonstrate through heterozygous enhancer cluster deletion and allele specific RNA-seq that enhancer clusters differ in their regulatory activity as the magnitude of the observed change in transcription upon enhancer cluster deletion varies greatly.
