Up-regulated claudin 7 expression in intestinal-type gastric carcinoma.
The disruption of tight junction protein expression in cancer might account for invasiveness, loss of cohesion, and lack of differentiation. Our cDNA array data indicated that claudin 7 was up-regulated in gastric carcinoma. We investigated the expression patterns and clinical implications of claudin 7 in gastric cancer. By immunohistochemical staining and Western blot, claudin 7 was significan...
متن کاملDifferential expression of claudin-4 between intestinal and diffuse-type gastric cancer.
Our previous microarray analysis of gastric cancer found that claudin-4 was differentially expressed between intestinal-type gastric cancer (IGC) and diffuse-type gastric cancer (DGC). Claudin-4 is a member of a large family of transmembrane proteins, claudins, essential in the formation and maintenance of tight junctions. To explore the roles of claudin-4 in the two histologically distinct typ...
متن کاملDown-regulated claudin-7 immunoexpression in urothelial carcinoma of the urinary bladder
OBJECTIVES To analyse the gene-expression level of claudin-7 in urothelial carcinoma (UC) of the urinary bladder, and its relationship with clinicopathological variables. MATERIALS AND METHODS This study included 68 specimens of UC of the bladder, comprising 35 with non-muscle-invasive (NMI), stage Ta-T1, and 33 with muscle-invasive (MI) tumours, T2-T4, and 26 of normal urothelium (NU). Total...
متن کاملClinicopathological significance of claudin-4 in gastric carcinoma
BACKGROUND Aberrant expression of claudin proteins has been reported in a variety of cancers. Previous studies have demonstrated that overexpression of claudin may promote tumorigenesis and metastasis through increased invasion and survival of tumor cells. However, the prognostic significance of claudin-4 in gastric cancer remains unclear. METHODS Immunohistochemistry was used to analyze the ...
متن کاملExpression of claudin-5, claudin-7 and occludin in oral squamous cell carcinoma and their clinico-pathological significance
BACKGROUND Claudin and occludin are the important tight junctions protein in human. The downregulation or upregulation of claudins and occludin might have a role in cancer development. The objective of this study was to investigate the expression of claudin-5, claudin-7 and occludin in oral squamous cell carcinoma (OSCC) and their relationships with the prognostically-related clinico-pathologic...
