CLDN6/9 (WO2017096163A1 Biosimilar) Recombinant Monoclonal Antibody

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
9. Cldn6 was decreased in alveolar type II-like epithelial cells (A549) and primary small airway epithelial cells when exposed to cigarette smoke ext PMID: 27982694
10. suggest that claudin-6 induces MMP-2 activation through claudin-1 membrane expression PMID: 27914788
11. Data show that claudin-6 (CLDN6) R209Q and occludin (OCLN) P24A mutations do not affect HCV pseudoparticles (HCVpp) entry. PMID: 26561856
12. The expression of ASK1 is correlated with the level of claudin-6 in cervical carcinoma cells and tissues. PMID: 26191261
13. High levels of CLDN6 are associated with non-small-cell lung cancer. PMID: 24710653
14. The expression of claudin-6 was down regulated in gastric cancer tissue. PMID: 23919729
15. Only some hepatitis C virus strains efficiently use CLDN6 for infection. PMID: 23775920
16. This work provides a proof of concept for the use of Claudin-6 to eliminate residual undifferentiated human pluripotent stem cells from culture. PMID: 23778593
17. Although claudin-6 and claudin-9 can serve as entry factors in cell lines, hepatitis C virus infection into human hepatocytes is not dependent on claudin-6 and claudin-9. PMID: 23864633
18. ASK1 signal may play a positive role in the inhibitory effect of claudin-6 in breast cancer. PMID: 22925655
19. Our results show that claudin-6 protein is significantly down-regulated in breast invasive ductal carcinomas PMID: 22455563
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
25. The up-regulation of claudin-6 expression in MCF-7 breast cancer cells suppresses their malignant phenotypes with a correlation with the restoration of tight junction integrity. PMID: 20367941
26. claudin-6, downregulates the malignant phenotype of breast carcinoma. PMID: 20215972
27. Claudin 6 was not found in epithelioid glioblastomas or rhabdoid glioblastomas. PMID: 20118769
28. CLDN6 and CLDN9, but not CLDN1, are expressed in peripheral blood mononuclear cells, an additional site of HCV replication. PMID: 17804490
29. claudin-6 and claudin-9 expressed in CD81+ cells also enable the entry of HCV pseudoparticles derived from six of the major genotypes. PMID: 18234789
30. CLDN6, clustered with CLDN9 at human chromosome 16p13.3, is a four-transmembrane protein with WWCC motif, defined by W-X(17-22)-W-X(2)-C-X(8-10)-C. PMID: 12736707
