Smarcad1 mediates microbiota-induced inflammation by coordinationg gene expression in the intestinal epithelium [H3K9me3 ChIP-seq]

Project description:How intestinal epithelial cells interact with the host immune system and the microbiota and how this is regulated at the gene expression level are critical questions. Smarcad1 is one of the most conserved chromatin remodelling factors, from yeast to human, with suggested functions in gene silencing, heterochromatin maintenance and genome stability. However, its role in tissue function is poorly understood. As this factor is highly expressed in the stem- and proliferative zone in the intestinal epithelium, we explored the role of this factor in this tissue. Specific deletion of Smarcad1 in the intestinal epithelium led to colitis resistance in the dextran sodium sulphate colitis model. Intestine tissue-specific deletion of Smarcad1 resulted in notable changes in gene expression in the small intestine and colon. Absence of Smarcad1 led to changes in chromatin accessibility and significant changes in histone H3K9me3 but not H3K9me2 over many sites, including many genes that are differentially regulated upon Smarcad1 deletion. Our study demonstrates that an innate immunity response can be coordinated by a chromatin remodelling factor.

ChIP-Seq of chromatin remodeler SMARCAD1 and H3K9me3 in female mouse embryonic stem cells (PGK12.1 XX)

Project description:Investigation of the co-occurance of the ATP-dependent chromatin remodeler SMARCAD1 and the histone modification H3K9me3 in the genome of PGK12.1 XX ES cells. ChIP-seq of endogenous SMARCAD1 was carried out in control and SMARCAD1-knockdown ES cells using a double crosslinking procedure. Additionally, H3K9me3 ChIP-seq was performed in double-cross linked control PGK12.1 XX cells. Input samples and precipitates with an IgG antibody were sequenced (Illumina HiSeq1500) as controls. Antibodies used were SMARCAD1 PAB15737 (Abnova) and H3K9me3 ab8898 (abcam).

Smarcad1 coordinates innate immunity-linked gene expression in the intestinal epithelium [wCO RNA-seq]

Project description:Smarcad1 is one of the most conserved chromatin remodelling factors, from yeast to human, with suggested functions in gene silencing, heterochromatin maintenance and genome stability. However, its role in tissue function is poorly understood. As this factor is highly expressed in the stem- and proliferative zone in the intestinal epithelium, we explored the role of this factor in this tissue. Specific deletion of Smarcad1 in the intestinal epithelium led to colitis resistance in the dextran sodium sulphate colitis model. Intestine tissue-specific deletion of Smarcad1 resulted in notable changes in gene expression in the small intestine, colon and organoids from small intestine. Strikingly, we found an increase of expression of several genes linked to innate immunity. Our study demonstrates that an innate immunity response can be coordinated by a chromatin remodelling factor. It highlights the role of intestinal epithelial cells in the colitis response and we identified candidate members of the gut microbiome that elicit an epithelial Smarcad1-dependent colitis response.

Intestine tissue-specific deletion of Smarcad1 resulted in notable changes in gene expression in the small intestine, colon and organoids from small intestine. Strikingly, we found an increase of expression of several genes linked to innate immunity and a dramatic increase of a Bglap3 coding for an osteocalcin isoform, a protein normally expressed in osteoblasts.
