Cdx2 has been identified as a marker of colon cancer in RNA-profiling experiments. We show here that the detection of Cdx2 protein by immunohistochemistry correlates well with RNA transcript levels as detected by oligonucleotide microarrays. Using tissue microarrays containing most normal tissue types and an antibody to the Cdx2 protein, strong diffuse Cdx2 staining was only seen in the nuclei of small and large intestinal epithelium and portions of the pancreatic duct system. In tissue microarrays containing 745 cancers from many anatomic sites, colonic adenocarcinomas showed strong extensive staining in 90% of cases, with adenocarcinomas of the stomach, esophagus, and ovary (endometrioid and mucinous types) showing extensive staining in only 20-30% of cases. Other types of carcinomas showed extensive staining in only

Pretreatment with 30 min of isoflurane attenuated the decrease in MAP and endothelium-dependent vasodilation, the acidosis, the increase in tumor necrosis factor-alpha, and the damage to the vascular endothelium associated with lipopolysaccharide-induced inflammation in rats. This study suggests that isoflurane pretreatment may protect the vasculature during inflammation.
