Gene Information from Publications

Publication Link Summary of findings
18251778 Cdx2 plays an important role in the regulation of intestinal claudin expression not only in gastric mucosa with intestinal metaplasia but also gastric carcinoma.
16627685 The gene expression profile of hepatic stem cells throughout life consists of high levels of expression of claudin-3 (CLDN-3).
17418912 When compared, small-cell-lung cancers, carcinoid tumors, and adenocarcinomas revealed significant differences re: CLDN3 expression.
17459057 Loss of claudin expression may enhance the grade of malignancy of gastric cancer in vivo.
17647191 CLDN3 overexpression can be used as a prognostic indicator in ovarian serous carcinomas and it may be a promising target for antibody-based therapy of ovarian carcinomas.
17545541 Claudin-3 and claudin-4 receptors are highly overexpressed in carcinosarcoma
12909588 Airway tight junctions are regulated by claudin interactions that confer the selectivity of the junction.
17103306 Claudin tight junction proteins in endoscopy biopsy samples showed Barrett's metaplasia contains more claudin-2 and claudin-3 than found in normal esophageal mucosa, but markedly lower claudins 1 and 5, indicating very different tight junction barriers.
17326053 Overexpression of claudin-3 is associated with uterine serous papillary carcinoma
16253248 The expression of claudin-1, -3 and -4 was upregulated 5.7-, 1.5- and 2.4-fold, respectively, in colorectal tumor tissues in comparison to the normal ones.
