Abstract
β-Catenin is a multifunctional protein that is involved in many physiological processes, including development, cell proliferation, cell migration, and apoptosis. However, the function of β-Catenin in crustacean is unknown. In this study, the first shrimp homologous gene of β-catenin in Marsupenaeus japonicus (i.e., Mjβ-catenin) was identified and characterized. The full-length of the complementary DNA of Mjβ-catenin is 3130 bp, including a 2463 bp open reading frame that encodes 821 amino acid. Multiple alignment of β-Catenin proteins suggested that the Armadillo/β-Catenin-like repeat domains were conserved. Phylogenetic analysis showed that β-Catenin from shrimp was clustered into one group with invertebrate β-Catenin. The transcription of β-catenin in various development stages of shrimp was detected and persistently increased as the shrimp matured. In adult shrimp, β-catenin was widely distributed in detected tissues and has the relatively high expression level in gills, hemocytes, testes, and ovaries. The transcripts of β-catenin in tissues of adult shrimp were significantly up-regulated at various time points after infecting with Staphylococcus aureus, Vibrio anguillarum, and white-spot syndrome virus. Furthermore, knockdown of β-catenin resulted in impaired bacterial clearance ability and increased virus copy in shrimp in vivo. Therefore, β-Catenin in shrimp participates in the development and immune response of shrimps.

Abstract
Intercellular junctions represent the key contact points and sites of communication between neighboring cells. Assembly of these junctions is absolutely essential for the structural integrity of cell monolayers, tissues and organs. Disruption of junctions can have severe consequences such as diarrhea, edema and sepsis, and contribute to the development of chronic inflammatory diseases. Cell junctions are not static structures, but rather they represent highly dynamic micro-domains that respond to signals from the intracellular and extracellular environments to modify their composition and function. This review article will focus on the regulation of tight junctions and adherens junctions by phosphatase enzymes that play an essential role in preserving and modulating the properties of intercellular junction proteins.

Abstract
INTRODUCTION Cell adhesion molecules (CAM) are required for maintaining a normal epithelial phenotype, and abnormalities in CAM expression have been related to cancer progression, including bladder urothelial carcinomas. There is only one study that correlates E-cadherin and Α-, Β- and y-catenin expression with prognosis of upper tract urothelial carcinomas. Our aim is to study the pattern of immune expression of these CAMs in urothelial carcinomas from the renal pelvis and ureter in patients who have been treated surgically. Our goal is to correlate these expression levels and characteristics with well-known prognostic parameters for disease-free survival. MATERIALS AND METHODS We evaluated specimens from 20 patients with urothelial carcinomas of the renal pelvis and ureter who were treated with nephroureterectomy or ureterectomy between June 1997 and January 2007. CAM expression was evaluated by immunohistochemistry in a tissue microarray and correlated with histopathological characteristics and patient outcomes after a mean follow-up of 55 months. RESULTS We observed a relationship between E-cadherin expression and disease recurrence. Disease recurrence occurred in 87.5% of patients with strong E-cadherin expression. Only 50.0% of patients with moderate expression and 0% of patients with weak or no expression of E-cadherin had disease recurrence (p = 0.014). There was also a difference in disease-free survival. Patients with strong E-cadherin expression had a mean disease-free survival rate of 49.1 months, compared to 83.9 months for patients with moderate expression (p = 0.011). Additionally, an absence of Α-catenin expression was associated with tumors that were larger than 3 cm (p = 0.003). CONCLUSIONS We demonstrated for the first time that immune expression of E-cadherin is related to tumor recurrence and disease-free survival rates, and the absence of Α-catenin expression is related to tumor size in upper tract urothelial carcinomas.

Abstract
Plakoglobin, or gamma-catenin, is found in both desmosomes and adherens junctions and participates in Wnt signalling. Mutations in the human gene are implicated in the congenital heart disorder, arrhythmogenic right ventricular cardiomyopathy (ARVC), but the signalling effects of plakoglobin loss in ARVC have not been established. Here we report that knockdown of plakoglobin in zebrafish results in decreased heart size, reduced heartbeat, cardiac oedema, reflux of blood between heart chambers and a twisted tail. Wholemount in situ hybridisation shows reduced expression of the heart markers nkx2.5 at 24 hours post fertilisation (hpf), and cmlc2 and vmhc at 48 hpf, while there is lack of restriction of the valve markers notch1b and bmp4 at 48 hpf. Wnt target gene expression was examined by semi-quantitative RT-PCR and found to be increased in morphant embryos indicating that plakoglobin is antagonistic to Wnt signalling. Co-expression of the Wnt inhibitor, Dkk1, rescues the cardiac phenotype of the plakoglobin morphant. beta-catenin protein expression is increased in morphant embryos as is its colocalisation with E-cadherin in adherens junctions. Endothelial cells at the atrioventricular boundary of morphant hearts have an aberrant morphology, indicating problems with valvulogenesis. Morphants also have decreased numbers of desmosomes and adherens junctions in the intercalated discs. These results establish the zebrafish as a model for ARVC caused by loss of plakoglobin function and indicate that there are signalling as well as structural consequences of this loss.

Abstract
OBJECTIVES To determine the value of the loss of expression of E-cadherin and cadherin associated molecules as useful markers for both prognosis and chemosensitivity in bladder cancer patients who have undergone radical cystectomy. PATIENTS AND METHODS In 55 paraffin embedded specimens of radical cystectomy at our hospital from 1982 to 2000, the expression of E-cadherin, alpha-, beta- and gamma-catenin was examined by immunohistochemical staining. To evaluate the prognostic significance of these molecules, Kaplan-Meier survival curves were constructed and a statistical analysis was calculated by a log-rank test. A multivariate test (tumor stage, tumor grade, lymph node metastasis, configuration, the expression of E-cadherin, alpha-, beta- and gamma-catenin) was performed to detect prognostic markers. RESULTS Normal expression was found in 33 cases (60.0%) for E-cadherin, 29 (52.7%) for alpha-catenin, 31 cases (56.4%) for beta-catenin, and 31 cases (56.4%) for gamma-catenin. The expression patterns for E-cadherin, alpha-, beta- and gamma-catenin were significantly correlated with each other (P < 0.01). Survival analysis showed a significant difference between normal and aberrant expression in each staining. A multivariate analysis revealed that the expression of alpha- catenin was an independent prognostic factor (P = 0.0191). In 23 patients that received adjuvant chemotherapy, there was a significant difference in survival between the normal and aberrant expression of alpha-catenin, but not other molecules. CONCLUSION Alpha-catenin may not only be a good prognostic marker, but also one of key molecules that determine the chemosensitivities in patients with invasive bladder cancer.

Abstract
OBJECTIVES To determine the value of loss of the expression of E-cadherin and cadherin-associated molecules as useful markers for both prognosis and bladder recurrence in patients with upper urinary tract cancer. MATERIALS AND METHODS In 61 paraffin-embedded nephroureterectomy specimens, the expression of E-cadherin and alpha-, beta-, and gamma-catenin was examined by immunohistochemical staining. To evaluate the prognostic significance, Kaplan-Meier survival curves were calculated and compared by the log-rank test. A multivariate test was performed to detect prognostic markers. RESULTS Normal expression was found in 32 cases (52.5%) for E-cadherin, 41 cases (67.2%) for alpha-catenin, 42 cases (68.9%) for beta-catenin, and 31 cases (50.8%) for gamma-catenin. The expression patterns of E-cadherin and alpha-, beta- and gamma-catenin were significantly correlated with each other. Survival analysis showed a significant difference between normal and aberrant expression in each staining. Multivariate analysis revealed that tumor stage and the expression of E-cadherin were independent prognostic factors for cause-specific survival. In contrast, there was no significant correlation between the expression of E-cadherin and alpha-, beta-, and gamma-catenin and bladder recurrence. CONCLUSION Our data suggest E-cadherin may be a good prognostic marker for patients with upper urinary tract cancer.

Abstract
Irradiation of the digestive system leads to alterations of the small intestine. We have characterized the disruption of the barrier integrity in rat ileum from 1 to 14 days following irradiation ranging from 6 to 12 Gy. The intestinal permeability to 14C-mannitol and 3H-dextran 70 000 was measured in vitro in Ussing chambers. In parallel to these functional studies, immunohistochemical analyses of junctional proteins (ZO-1 and beta-catenin) of ileal epithelium were performed by confocal microscopy. Irradiation with 10 Gy induced a marked decrease in epithelial tissue resistance at three days and a fivefold increase in mannitol permeability, without modifications of dextran permeability. A disorganization of the localization for ZO-1 and beta-catenin was also observed. At 7 days after irradiation, we observed a recovery of the organization of junctional proteins in parallel to a return of intestinal permeability to control value. In addition to these time-dependent effects, a gradual effect on epithelial integrity of the radiation doses was observed 3 days after irradiation. This study shows a disruption of the integrity of the intestinal barrier in rat ileum following abdominal X-irradiation, depending on the time postirradiation and on the delivered dose. The loss of barrier integrity was characterized by a disorganization of proteins of tight and adherent junctions, leading to increased intestinal permeability to mannitol.

Abstract
It is now widely recognized that alterations in the adhesion properties of neoplastic cells may play a pivotal role in the development and progression of the malignant phenotype in a range of tumor types. The cadherins and catenins, being the prime mediators of cell-cell adhesion, are intimately involved in the control of morphological differentiation and cellular proliferation; loss of their intercellular function allows malignant cells to escape from their site of origin, degrade the extracellular matrix, acquire a more motile and invasive phenotype, and, finally, invade and metastasize. In addition to participating in tumor invasiveness and metastasis, the E-cadherin-catenin complex is fundamental for the establishment and maintenance of multicellular organisms and regulates or significantly contributes to a variety of functions, including signal transduction, cell growth, differentiation, site-specific gene expression, morphogenesis, immunologic function, cell motility, wound healing, and inflammation. We reviewed the role of the E-cadherin-catenin complex in tumor development and presented the potential clinical applications of these molecules.

Abstract
There is a growing body of evidence suggesting that alterations in the adhesion properties of neoplastic cells may play a pivotal role in the development and progression of bladder cancer. Loss of intercellular adhesion and the desquamation of cells from the underlying lamina propria allows malignant cells to escape from their site of origin, degrade the extracellular matrix, acquire a more motile and invasive phenotype, and finally invade and metastasize. In addition to participating in tumor invasiveness and metastasis, adhesion molecules regulate or significantly contribute to a variety of functions, including signal transduction, cell growth, differentiation, site-specific gene expression, morphogenesis, immunologic function, cell motility, wound healing, and inflammation. To date, a diverse system of transmembrane glycoproteins have been identified that mediate the cell-cell and the cell-extracellular matrix adhesion. The main families of adhesion molecules are the cadherins, integrins, members of the immunoglobulin superfamily, and selectins. We review the recent data regarding the role of selected adhesion molecules in the pathogenesis of bladder cancer and their clinical exploitation as biomarkers of this malignant disease.

Abstract
The low density lipoprotein receptor-related protein (LRP) is a multifunctional endocytic receptor with the ability to bind and endocytose several structurally and functionally distinct ligands. The 39 kDa receptor-associated protein (RAP) is an endoplasmic reticulum (ER) resident protein, which is believed to function intracellularly as a molecular chaperone for LRP and to regulate its ligand binding activity along the secretory pathway. Mouse heparin binding protein-44 (HBP-44) is a homologue of human RAP. Using a recombinant form of HBP-44 expressed in Escherichia coli cells as a highly specific ligand for LRP, we demonstrated that HBP-44 coated on cell culture plates mediates the cell-substratum adhesion of mouse 3T3 fibroblasts in a dose-dependent manner, with 50% attachment at the concentration of 0.2 micrograms/ml. Ligand blot analysis with HBP-44 of whole cell extracts and the materials precipitated by anti-LRP antibodies revealed that the receptor for HBP-44 on NIH/3T3 cells was LRP. The results suggest that LRP serves as a cell adhesion receptor in some cells.
