In this study, we focused on the influence of progesterone and its receptor in invasion and MMPs on endometrial carcinoma cells. The growth of Ishikawa cells, to which an progesterone receptor form B (PR-B) expressing vector was transfected, was inhibited by progesterone as was the inhibition of the expression of cyclin D1. By invasion assay, in conditions(More)
Squamous differentiation occurs in 25 to 50% of endometrial endometrioid adenocarcinomas. In this study, we analyzed the immunohistochemical expression and localization of beta- and gamma-catenin, molecular changes in the beta-catenin gene, and the subcellular localization of the desmosomal component protein, desmoplakin, by laser scanning microscopy in 35(More)
Tumor suppressor p53 is a transcription factor that induces growth arrest and/or apoptosis in response to cellular stress. To identify novel p53-inducible genes, we compared the expression of genes in normal mouse embryo fibroblasts (MEFs) to p53-null cells by cDNA representational difference analysis. We report here that expression of endogenous sodium(More)
The effect of intraluminal bile on the well-known feedback regulatory mechanism of exocrine pancreatic secretion exerted by intraluminal trypsin was investigated in conscious rats with pancreatic, biliary and duodenal fistulae. The stimulated pancreatic enzyme secretion caused by diversion of bile-pancreatic juice from the intestine was apparently(More)
In the present study, we analyzed the immunohistochemical findings for the RA receptor (RAR), retinoic X receptor (RXR) and hypermethylation of promoter-region CpG island methylation of RAR-beta2. Immunohistochemistry indicated that though RXR-alpha and -gamma were present in endometrial hyperplasia and cancer, other retinoid receptors were only weakly(More)
