Project description:Microarray analysis of IECs from Tlr5+/+ and Tlr5â/â mice stimulated with either medium alone or flagellin (1 µg/ml); to elucidate TLR5-mediated immune responses in IECs. Experiment Overall Design: IECs from Tlr5+/+ and Tlr5â/â mice were treated with or without flagellin (1 ïg/ml) for 4 h. Total RNA was extracted with an RNeasy kit (Qiagen), and purified using an Oligotex mRNA Kit (Pharmacia). Fragmented and biotin-labeled cDNA was synthesized from 100 ng purified mRNA using the Ovation Biotin System (Nugen), according to the manufacturerâs protocol. cDNA was hybridized to Affymetrix Murine Genome 430 2.0 microarray chips (Affymetrix) according to the manufacturerâs instructions. Hybridized chips were stained, washed and scanned using a GeneArray Scanner (Affymetrix). Data analysis was performed with Microarray Suite software (Version 5.0, Affymetrix) and GeneSpring software (Silicon Genetics).

Project description:The development and severity of inflammatory bowel diseases (IBD) and other chronic inflammatory conditions can be influenced by host genetic and environmental factors, including signals derived from commensal bacteria. However, the mechanisms that integrate these diverse cues remain undefined. Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3ΔIEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3ΔIEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3ΔIEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis. Strikingly, rederivation of HDAC3ΔIEC mice into germ-free conditions revealed that dysregulated IEC gene expression, Paneth cell homeostasis, and intestinal barrier function were largely restored in the absence of commensal bacteria. Collectively, these data indicate that the HDAC3 is a critical factor that integrates commensal bacteria-derived signals to calibrate epithelial cell responses required to establish normal host-commensal relationships and maintain intestinal homeostasis. Analyses of histone acetylation in primary IECs from HDAC3FF (3 biologic replicates) and HDAC3ΔIEC (3 biologic replicates) mice were conducted utilizing ChIP-seq for H3K9Ac.

Here we demonstrate that intestinal epithelial cells (IECs) isolated from IBD patients exhibit decreased expression of the epigenome-modifying enzyme histone deacetylase 3 (HDAC3). Further, genome-wide analyses of murine IECs that lack HDAC3 (HDAC3?IEC) revealed that HDAC3 deficiency resulted in dysregulated gene expression coupled with alterations in histone acetylation. Critically, conventionally-housed HDAC3?IEC mice demonstrated loss of Paneth cells, impaired IEC function and alterations in the composition of intestinal commensal bacteria. In addition, HDAC3?IEC mice exhibited significantly increased susceptibility to intestinal damage and inflammation, indicating that epithelial expression of HDAC3 plays a central role in maintaining intestinal homeostasis. Strikingly, rederivation of HDAC3?IEC mice into germ-free conditions revealed that dysregulated IEC gene expression, Paneth cell homeostasis, and intestinal barrier function were largely restored in the absence of commensal bacteria. Collectively, these data indicate that the HDAC3 is a critical factor that integrates commensal bacteria-derived signals to calibrate epithelial cell responses required to establish normal host-commensal relationships and maintain intestinal homeostasis. In this study, we performed gene expression profiling to examine how the transcriptional profiles in primary live, EpCAM+ IECs from the large intestine differed between control HDAC3FF mice (3 biological replicates) and IEC-intrinsic knockout HDAC3?IEC mice (3 biological replicates).
