  • 基因功能參考文獻(xiàn)：
    1. Antibodies recognizing native CLDN6 as displayed on cell surfaces and mediating complement-dependent cytotoxicity were elicited in vaccinated animals. The data suggest applications of CLDN6 displaying Virus-like particles in cancer immunotherapy. PMID: 29131519
    2. these results suggest that Helicobacter pylori lipopolysaccharide induces TLR2 expression in the gastric adenocarcinoma cells, and that the longer the exposure to lipopolysaccharide, the greater the expression of TLR2 in the cell membrane; consequently the expression of claudin-4, -6, -7 and -9 also increases PMID: 29031421
    3. Study provides evidence that high expression of CLDN6 confers chemoresistance on breast cancer which is mediated by GSTP1, the activity of which is regulated by p53. PMID: 29116019
    4. CLDN6 enhances the chemoresistance to ADM via activating the AF-6/ERK signaling pathway and up-regulating cancer stem cell characters in MDAMB231 cells. PMID: 29159771
    5. we demonstrated that the downregulation of CLDN6 is regulated through promoter methylation by DNMT1, which depends on the SMAD2 pathway, and that CLDN6 is a key regulator in the SMAD2/DNMT1/CLDN6 pathway to inhibit EMT, migration and invasion of breast cancer cells PMID: 28867761
    6. In conclusion, this information from bioinformatics analysis will help future attempts to better understand CLDN6 regulation and functions. PMID: 28656265
    7. high expression of CLDN 6 was observed in approx. 65% of the myxofibrosarcomas, whereas the benign soft tissue tumors did not show a high expression of CLDN 6. The expression of CLDN 6 in the myxofibrosarcomas was significantly higher than those of other tumor specimens. Among the myxofibrosarcomas, the high expression of CLDN 6 was correlated with high FNCLCC grades and high AJCC stages. PMID: 28476380
    8. Results show that DNA methylation down-regulates CLDN6 expression through MeCP2 binding to the CLDN6 promoter, deacetylating H3 and H4, and altering chromatin structure, consequently promoting migratory and invasive phenotype in breast cancer cells. PMID: 27461117

    18. ASK1 signal may play a positive role in the inhibitory effect of claudin-6 in breast cancer. PMID: 22925655

    20. CLDN6 is not a specific biomarker for atypical teratoid rhabdoid tumors as it is expressed in a variety of other pediatric CNS and soft tissue tumors. PMID: 21989342
    21. 17beta-E2 might regulate the expression of claudin-6 and inhibit the proliferation and migration of MCF-7 cells. PMID: 20388399
    22. Increased expression of claudin-6, claudin-7, or claudin-9 is sufficient to enhance tumorigenic properties of a gastric adenocarcinoma cell line. PMID: 20874001
    23. CLDN6 may be a useful positive marker to help further identify atypical teratoid/rhabdoid tumors for diagnostic and treatment purposes PMID: 19220299
    24. Claudins 6, 7, and 9 expressions are closely related to gastric carcinogenesis PMID: 19960275
