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.
18283635 MMP-2, MMP-9 and claudin-4 expression may be phenotypic features, distinguishing intestinal-type and diffuse-type gastric cancer.
17678893 The modulation of claudin-4 activity by PKCepsilon may not only provide a mechanism for disrupting TJ function in ovarian cancer, but may also be important in the regulation of TJ function in normal epithelial cells.
17709988 vinculin plays a role in growth regulation of neuroendocrine tumors and in expression of CLD4
17418912 When compared, small-cell-lung cancers and carcinoid tumors, adenocarcinomas, and squamous cell carcinomas in CLDN4 expression.
17459057 Loss of claudin expression may enhance the grade of malignancy of gastric cancer in vivo.
17651017 Our data suggest that JUND and CLDN4 are critical mediators of the antiproliferative and antiviral effects of type I IFNs and further confirm the functional importance of the DNA-binding domain of Stat2.
15643498 claudin 4 may play a role in the disruption of cell-to-cell adhesion in diffuse type gastric cancer and in a loss of differentiation.
17545541 Claudin-3 and claudin-4 receptors are highly overexpressed in carcinosarcoma
17359339 Tight junction proteins contribute to the permeability barrier in epidermal keratinocytes
