  • 產品描述：

    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.

實驗應用：藥物相關研究

產品評價： CLDN6是CLDN家族的重要成員，在維持TJs的功能中起著重要作用。CLDN6在卵巢癌、睪丸癌、肝細胞癌、肺腺癌等多種癌癥中均有特異性表達，在癌細胞上有差異表達，在成人正常組織中幾乎檢測不到，是潛在的靶點。CLDN6是一個4次跨膜的蛋白。CUSA Bio通過其特有的Vlp平臺表達的全長重組人CLDN6蛋白，具有較好的生物活性，我使用CSB-MP005508HU(A4)產品進行ELISA實驗，EC50為1.726-3.525 ng/ml，后續(xù)實驗進展順利，對我的研究幫助很大，考慮繼續(xù)大量采購！

  • 功能：
    Plays a major role in tight junction-specific obliteration of the intercellular space.; (Microbial infection) Acts as a receptor for hepatitis C virus (HCV) entry into hepatic cells.

    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
