(Submitter supplied) Glucocorticoids (GCs) are important hormones involved in the regulation of multiple physiologic functions. GCs are also widely used in anti-inflammatory/immunosuppressant drugs. GCs are synthesized by the adrenal cortex as part of the hypothalamus-pituitary-adrenal axis and also by intestinal epithelial cells, among other peripheral sites. GCs are one of the main therapy choices for the exacerbations of inflammatory bowel disease, but they are not useful to prolong remission, and development of tolerance with secondary treatment failure is frequent. more...

(Submitter supplied) Histone deacetylases (Hdac) remove acetyl groups from proteins, influencing global and specific gene expression. Hdacs control inflammation, as shown by Hdac inhibitor-dependent protection from DSS-induced murine colitis. While tissue-specific Hdac knockouts show redundant and specific functions, little is known of their intestinal epithelial cell (IEC) role. We have shown previously that dual Hdac1/Hdac2 IEC-specific loss disrupts cell proliferation and determination, with decreased secretory cell numbers and altered barrier function. more...

(Submitter supplied) Background & Aims: HNF4α is an important transcriptional regulator of hepatocyte and pancreatic function. Hnf4α deletion is embryonically lethal with severe defects in visceral endoderm formation, liver maturation and colon development. However, the precise role of this transcription factor in maintaining homeostasis of the adult intestine remains unclear. Herein, we aimed to elucidate the adult intestinal functions of Hnf4α. more...

Analysis of hepatocyte nuclear factor 4 alpha (HNF4-alpha) deficient colons of 1 year old animals. HNF4-alpha is a transcription factor. Deletion of HNF4-alpha confined to the epithelial colon. Results provide insight into the role of HNF4-alpha in maintaining intestinal inflammatory homeostasis.

(Submitter supplied) Analysis of expression changes in renal collecting duct epithelial cells by adenoviral mediated Krüppel like transcription factor 5 (KLF5) overexpression. KLF5 is a key regulator of static and inflammatory stage in renal collecting duct epithelial cells. We thought these results provide insights into downstream genes of KLF5 in renal collecting duct epithelial cells.

(Submitter supplied) Background and Aims: Individuals with ulcerative colitis (UC) are at increased risk for colorectal cancer, although underlying mechanisms are incompletely understood. We sought to identify a potential gene expression signature in non-dysplastic distal mucosa that as a “genetic field effect” could be a marker for remote neoplastic lesions. Results: 468 genes were significantly up-regulated and 541 genes were significantly down-regulated >2-fold in UC patients with neoplasia compared to UC patients without neoplasia. more...

(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...
