Project description:Microarray analysis of HT-29 cells co-cultured with tumor necrosis factor (TNF-a) in the presence or absence of polymeric formula as used for Exclusive Enteral Nutrition (EEN) therapy. Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium.

Results provide insights into the molecular mechanisms underlying the anti-inflammatory effect of polymeric formula on intestinal epithelium. Total RNA obtained from 9 samples of HT-29 cells. Six samples were treated with TNF-a in the presence (3 samples) or absence (3 samples) of Polymeric Formula. Three samples were untreated and used as a control.
Project description:Necrotizing Enterocolitis (NEC) is an inflammation causing injury to the bowel in newborns. This project uses a rodent model that mimics the intestinal pathological changes seen in NEC to study the effect of formula feeding and hypoxia on NEC development

Project description:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:BACKGROUND AND AIMS: Loss of epithelial cell homeostasis and apoptosis highly con-tribute to intestinal inflammation. While endoplasmic reticulum unfolded protein response (UPR) has been implicated in chronic intestinal inflammation, functional correlation between UPR-related C/EBP homologous protein (CHOP) expression and CHOP-mediated programming towards inflammation-related disease susceptibility remains unclear. In this study, we generated the new mouse model ChopIEC Tg/Tg to investigate consequences of intestinal epithelial cell (IEC)-specific CHOP overexpression. Transcriptional profiling of transgenic mice identified a set of CHOP-dependent target genes related to inflammatory and microbial defense program in the intestinal epithelium. Effect of CHOP overexpression in intestial epithelial cells was investigated on epithelial homeostasis using transgenic mice Disease-free mice do not show enhanced apoptotic signaling Intestinal epithelial cells were isolated from 12 week old females
Project description:Transcriptional profiling of human mesenchymal stem cells comparing normoxic MSCs cells with hypoxic MSCs cells. Hypoxia may inhibit senescence of MSCs during expansion. Goal was to determine the effects of hypoxia on global MSCs gene expression.
