Genome-wide analysis of MNase digestibility in wild type or Lsh depleted murine embryonic fibroblasts

We report here differences in MNase digestibility comparing murine embryonic fibroblasts (MEFs) with and without Lsh. In the first set of samples we compare primary MEFs derived from Lsh+/+ (pMEF_WT5) or Lsh-/- (pMEF_KO6) day 13.5 gestation embryos. In a second set we compare MEFs form conditional Lsh knockout mice before (GC-OHT-NC) or after 48 hours of tamoxifen inducible cre-recombinase expression (GC-OHT-2D). In a third set we compare Lsh knockout (Lsh cko) MEFs before (IAA-0h) and after 72 hours of IAA induced proteolytical degradation of Lsh (IAA-3D). In a fourth set we compare Lsh knockout MEFs before (IAA-0h-2) and after 7 hours of IAA induced proteolytical degradation of Lsh (IAA-7h) or after 24 hours (IAA-24). Lsh depletion leads to specific changes in chromatin accessibility at potential enhancer sites. Overall design: Genome-wide maps of MNase digestiblity in MEFs in the presence or absence of Lsh.
