(Submitter supplied) The intestinal epithelium is an immunologically active barrier adapted for a low oxygen environment. Its role is implicated in the pathophysiology of various diseases, including inflammatory bowel disease (IBD) and colorectal cancer. Patient-derived intestinal epithelial organoids (IEOs) mimic the architecture and cell type composition of the intestine and can be used for disease modeling and personalized drug screening. more...

(Submitter supplied) Treatment of inflammatory bowel disease (IBD) is challenging, with a series of available drugs each helping only a fraction of patients. Patients may face time-consuming drug trials while the disease is active, thus there is an unmet need for biomarkers and assays to predict drug effect. It is well known that the intestinal epithelium is an important factor in disease pathogenesis, exhibiting physical, biochemical and immunologic driven barrier dysfunctions. more...

(Submitter supplied) Objective: Children with very early onset inflammatory bowel disease (VEO IBD) present with more extensive, severe, and refractory disease than older children and adults with IBD. In the current study, we evaluated functional and transcriptomic differences in epithelial cells from patients with VEO and older onset IBD compared to controls. Design: We established enteroids and colonoid lines from patients with VEO and older onset IBD and control patients. more...

(Submitter supplied) Intestinal organoids have the potential to replicate cellular diversity and functional biology of the human gut, suggesting their application in Inflammatory Bowel Disease (IBD) research. Insufficient characterization at the molecular, cellular, and functional level has remained a barrier to their use in drug discovery. We profile intestinal organoids and Transwell-monolayers derived from ileum and colon tissue of control and IBD subjects. more...

(Submitter supplied) A human colon carcinoma-derived cell line LS174T was modified to overexpress NICD, intracellular domain of Notch1, upon doxycycline addition (designated as LS174T-tetON-NICD cells), using the T-rex system (Invitrogen). We have previously shown that these cells can overexpress NICD under the control of CMV promoter (Okamoto R et al, Am J Physiol, 296(1):G23-35, 2009), and the amont of the overexpressed NICD protein reaches to the maximal level in early as 3 hours from doxycycline addition (100ng/ml), which persists for up to 24 hours. more...

(Submitter supplied) In order to investigate the response of epithelium to butyrate, we generated in vitro epithelial organoid cultures from colon samples of non-IBD controls and they were stimulated with different doses of butyrate. The transcriptional signature revealed that butyrate negatively regulated proliferation and cell cycle, induced a protective response to oxidative stress and regulated genes related to the immune response.

(Submitter supplied) Acute damage to the intestinal epithelium can be repaired via de-differentiation of mature intestinal epithelial cells to a stem cell state, but there is a lack of knowledge on how these stem cells function after chronic injury, such as in inflammatory bowel disease (IBD). We developed a chronic injury model in human colonoid monolayers by repeated rounds of air-liquid interface and submerged growth. more...

(Submitter supplied) We report that repeated rounds of media submergence damage of human colon organoids led to the inability of cells to regrow and respond appropriately to TLR stimulation. We also identified mRNA expression and DNA methylation changes in genes associated with IBD and colon cancer.

(Submitter supplied) To understand the extent of Smad-mediated gene regulation in the colon, we isolated colon epithelium from Smad4ΔLrig1 and from Smad4+ control mice (either mice lacking a CreERT allele and treated with tamoxifen, or mice bearing a CreERT allele but treated with vehicle only) and analyzed the colonic epithelium by RNAseq. The ability of TGFβ1 and/or BMP2 to block TNF-mediated induction of Ccl20 from our study suggests that these Smad-mediated pathways may act as gatekeepers for induction of other inflammation-associated genes. more...

(Submitter supplied) UNIFI was a randomized placebo-controlled phase 3 clinical trial evaluating the efficacy and safety of ustekinumab (ClinicalTrials.gov Identifier: NCT02407236). Gene expression profiling by microarrays was carried out at baseline on biopsies from the sigmoid colon (15-20cm from anal verge) of patients (n=550) with moderate-to-severe ulcerative colitis and of healthy subjects (n=18). Ulcerative colitis patients received placebo (n=186) or ustekinumab (n=364). more...

(Submitter supplied) Purpose: This study aims to the downstream transcriptional networks controlled by JUN and DDIT which are critical for RGC death Methods: RNA was isolated from the retinas of wild-type mice and mice deficient in Jun, Ddit3, and both Jun and Ddit3 three days after mechanical optic nerve crush injury (CONC), and was subjected to RNA-sequecing. Results: This study identified downstream transcriptional changes after injury included both neuronal survival and pro-inflammatory signaling that were attenuated to differing degrees by loss of Ddit3, Jun, and Ddit3/Jun. more...

(Submitter supplied) We applied RNA-seq analysis of total RNA isolated from laser capture microdissected intestinal epithelium. The analysis aimed at charactericing the gene expression seen in ulcer-associated cell lineage epithelial cells, and to contrast this with that of healthy control epithelium and epithelium from inflammatory bowel disease-patients with active inflammation.

(Submitter supplied) Wnt signaling plays a pivotal role in colorectal cancer. Intrinsic activation of Wnt by mutational events, such as mutations in the tumor suppressor gene APC, represents the most frequent initiating event in this disease background. Long truncated versions of APC retain partial functionality, which leads to a sub-maximal, “just right” activation state of Wnt signaling supposed to be beneficial for disease initiation. more...

(Submitter supplied) Organoids are a valuable 3D model to study the differentiated functions of the human intestinal epithelium. They are a particularly powerful tool to measure epithelial transport processs in health and disease. Though biological assays such as organoid swelling and intraluminal pH measurements are well established, their underlying functional genomics are not well characterized. Here we combine genome-wide analysis of open chromatin by ATAC-seq with transcriptome mapping by RNA-seq to define the genomic signature of human intestinal organoids (HIOs). more...
