  • 产品描述：

    This Human Claudin-6 (CLDN6) recombinant protein was produced in Mammalian cell, where the gene sequence encoding Human CLDN6 (1-220aa) was expressed with the C-terminal 10xHis tag. The activity was validated by its binding ability in a functional ELISA. This Human CLDN6 recombinant protein was developed through the Virus-Like Particles (VLPs) Platform. It is a four-pass transmembrane protein.

    CLDNs are a class of TJ (Tight junctions) transmembrane proteins. From the perspective of spatial structure, most CLDNs contain four transmembrane regions and two extracellular loops, and an intracellular loop with amino and carboxyl termini located in the cytoplasm. Crystal structures of some CLDNs reveal a unique protein fold of the left-handed helical bundle and the four transmembrane helices of the extracellular caudal domain. 
    CLDN6 can activate cell adhesion signaling and modulate the activity of nuclear receptors. CLDN6 is expressed in a variety of embryonic epithelia, induces the formation and polarity of epithelial cell junctions, and is involved in the differentiation of stem cells into the epithelium. Collectively, CLDN6 is an important part of the CLDN family and plays an important role in maintaining the function of TJs. CLDN6 is specifically expressed in various cancers such as ovarian cancer, testicular cancer, hepatocellular carcinoma and lung adenocarcinoma, differentially expressed on cancer cells, and almost undetectable in adult normal tissues, making it a potential target point.

实验应用：药物相关研究

产品评价： CLDN6是CLDN家族的重要成员，在维持TJs的功能中起着重要作用。CLDN6在卵巢癌、睾丸癌、肝细胞癌、肺腺癌等多种癌症中均有特异性表达，在癌细胞上有差异表达，在成人正常组织中几乎检测不到，是潜在的靶点。CLDN6是一个4次跨膜的蛋白。CUSA Bio通过其特有的Vlp平台表达的全长重组人CLDN6蛋白，具有较好的生物活性，我使用CSB-MP005508HU(A4)产品进行ELISA实验，EC50为1.726-3.525 ng/ml，后续实验进展顺利，对我的研究帮助很大，考虑继续大量采购！

    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.

Among the myxofibrosarcomas, the high expression of CLDN 6 was correlated with high FNCLCC grades and high AJCC stages. PMID: 28476380
