Project description:Cdx2/IL-1beta mice have less intestinal metaplasia at the squamocolumnar junction thanIL-1beta mice alone. This study was to identify a mechanism for this effect by examining differences in gene expression patterns when Cdx2 is co-expressed. We dissected out intestinal metaplasia nodules from the squamocolumnar junction in Cdx2/IL-1beta mice and Il-1beta mice and measured gene expression on a Mouse Gene 2.0ST Affymetrix array in Oct 2013.

Project description:Esophageal adenocarcinoma (EAC) has the fastest increase of any cancer in the US and Europe, and arises in the setting of BarrettM-bM-^@M-^Ys esophagus (BE), defined by replacement of normal squamous epithelium with columnar intestinal-like epithelium. BE is thought to result from chronic esophageal inflammation but has been elusive to model in animals. Herein, we have generated the first transgenic mouse model of BarrettM-bM-^@M-^Ys esophagus through overexpression of interleukin-1M-CM-^_ (IL-1M-NM-2). IL-1M-NM-2 overexpression in the mouse esophageal mucosa induces chronic inflammation that progresses to intestinal metaplasia, with characteristic expression of TFF2, Bmp4 and Cdx2. With aging, IL-1b transgenic mice progress to esophageal adenocarcinoma (EAC) but the process is markedly accelerated by exposure to bile acids and/or nitrosamines, resembling the human counterpart. Moreover, progenitor cells present in the gastric cardia, but absent from the esophagus in humans and mice, are increased in BE, suggesting the cell of origin in the gastric cardia Comparison of BE and EAC tissue from the mouse with normal squamous epithelium from the mouse.

Project description:Esophageal adenocarcinoma (EAC) has the fastest increase of any cancer in the US and Europe, and arises in the setting of Barrett’s esophagus (BE), defined by replacement of normal squamous epithelium with columnar intestinal-like epithelium. BE is thought to result from chronic esophageal inflammation but has been elusive to model in animals. Herein, we have generated the first transgenic mouse model of Barrett’s esophagus through overexpression of interleukin-1ß (IL-1β). IL-1β overexpression in the mouse esophageal mucosa induces chronic inflammation that progresses to intestinal metaplasia, with characteristic expression of TFF2, Bmp4 and Cdx2. With aging, IL-1b transgenic mice progress to esophageal adenocarcinoma (EAC) but the process is markedly accelerated by exposure to bile acids and/or nitrosamines, resembling the human counterpart. Moreover, progenitor cells present in the gastric cardia, but absent from the esophagus in humans and mice, are increased in BE, suggesting the cell of origin in the gastric cardia

Project description:We used microarrays to identify the gene expression accompanied with growth arrest caused by the transduction of CDX1 or CDX2. Ectopic expression of CDXs causes intestinal metaplasia, which is thought to be precancerous legion of gastric cancer. On the contrary, there were some studies reported that CDX2 positive gastric cancers showed better prognosis or tumor suppressive activity. To evaluate the effect of exogenous CDX expression in gastric cancer cells, we transducted CDX1 or CDX2 in two CDX negative expression cell lines, MKN7 and TMK1.

Project description:Neutrophil abscess formation is critical in innate immunity against many pathogens. Here, the mechanism of neutrophil abscess formation was investigated using a mouse model of Staphylococcus aureus cutaneous infection. Gene expression analysis of S. aureus-infected skin revealed that induction of neutrophil recruitment genes was largely dependent upon IL-1beta/IL-1R activation. Unexpectedly, using IL 1beta reporter mice, neutrophils were identified as the primary source of IL-1beta at the site of infection. Furthermore, IL-1beta-producing neutrophils were necessary and sufficient for abscess formation and bacterial clearance. S. aureus-induced IL 1beta production by neutrophils required TLR2, NOD2, FPRs and the ASC/NLRP3 inflammasome. Taken together, IL-1beta and neutrophil abscess formation during an infection are functionally, spatially and temporally linked as a consequence of direct IL-1beta production by neutrophils.

Lesional skin biopsies obtained from C57BL/6J WT mice or IL-1R-deficient mice at 4 hours post-infection with Staphylococcus aureus. Uninfected skin biopsies were also collected from WT and IL-1R-deficient mice.

Project description:Rat primary chondrocyte: Control vs. IL-1beta treated
| PRJNA149317 | ENA
Project description:Purpose: To demonstrate the role of Transcription factor Runx2 in primary chondrocytes with or without IL-1beta. Method: Fragmented DNA samples were collected from primary chondrocytes of 5-day-old Runx2-Biotin-FLAG-tag mice, cultured with or without IL-1beta. Results: More than 20,000 and 10,000 peaks were gained from chondrocytes without and with IL-1beta, resepectively. Conclusions: Runx2 are associated cellular process and extracellular matrics transcription in primary chondrocytes.
