Satb2 deletion in colon approach to treat short bowel syndrome

ABSTRACT: Loss of the transcription factor Satb2 converts mouse colonic epithelium into an ileal type. Here, we report that Satb2 gene deletion alleviates SBS by replacing diminished absorptive function and by inducing lymphovascular channels in the proximal colon. Enhanced nutrient absorption following Satb2 loss increased body weight and survival of mice with SBS. Deletion of SATB2 by adeno-associated viral delivery of CRISPR Split Cas9 to human colon organoids, followed by xenotransplantation into mice, resulted in ileal morphology and expression of ileal marker genes. This approach offers a feasible strategy for future treatment of SBS.

ChIP-seq for Satb2 in E15 cortex

Project description:The goal of the study was to identify the binding site of SATB2 in wild-ype cortex by performing ChIP-seq using SATB2 antibody. E15 cortical tissues were dissected, lysed and fixed. Chromatin was prepared by sonication. Sequences bound by SATB2 protein was precipitated using a SATB2 antibody. Sequencing was performed on Illumina Genome Analyzer II. SATB2 binding peaks were called using MACS. ChIP for Satb2, followed by sequencing on Illumina Genome Analyzer II platform

Role of Satb1 and Satb2 in embryonic stem cells

Project description:Satb1 and Satb2 are regulators of higher order chromatin in T cells and osteoblasts repectively. We were interested if Satb1 and Satb2 play a role in the regulation of gene expression in ES cells. This SuperSeries is composed of the following subset Series: GSE17487: Expression data in WT and Satb1-/- ES cells GSE17488: Expression data in WT and ES cells overexpressing Satb1 GSE17489: Expression data in WT and ES cells overexpressing Satb2 Refer to individual Series

Chromatin reorganization during myoblast differentiation involves the caspase-dependent removal of SATB2 [ChIP-seq]

Project description:Induction of lineage-specific gene programs are strongly influenced by alterations in local chromatin architecture. However, key players that impact this genome reorganization remain largely unknown. Here, we report that removal of special AT-rich binding protein 2 (SATB2), a nuclear protein known to bind matrix attachment regions, is a key event in initiating myogenic differentiation. Deletion of myoblast SATB2 in vitro initiates chromatin remodeling and accelerates differentiation, while in vivo ablation depletes the muscle progenitor pool. Genome wide analysis indicates that SATB2 binding influences both chromatin loop and sub-TAD domain formation. These chromatin changes are both repressive and inductive, as loss of SATB2 leads to expression of differentiation regulatory factors and inhibition of genes that impair this process. Finally, we noted that the differentiation-specific decline in SATB2 protein is dependent on a caspase 7-mediated cleavage event. Taken together, this study demonstrates that temporal control of SATB2 protein is critical for shaping the chromatin environment and coordinating the myogenic differentiation program

Expression data in WT and ES cells overexpressing Satb2

Project description:Satb1 and Satb2 are regulators of higher order chromatin in T cells and osteoblasts repectively. We were interested if Satb1 and Satb2 play a role in the regulation of gene expression in ES cells. ES cells which can inducibly express Satb1 or Satb2 were generated using the tet-ON system. In this experiment, we compared gene expression in uninduced cells to that in cells which had been induced for 24h to express Satb2 ectopcially at very high levels.
