  • 產(chǎn)品描述：

    The Recombinant Human Mesothelin MSLN is derived from mammalian cells with purity over 92% on SDS-PAGE. It contains AA Glu296-Gly580 and the molecular weight of this domain is 59.6kDa, and a human IgG1 Fc tag was fused at N-terminus.
    Recombinant Human Mesothelin is valuable in cancer research as a target for therapy. It is also used for detecting anti-MLSN antibodies in functional ELISA.
    Mesothelin is widely expressed in normal mesothelial cells, oncogenic mesothelial cells, and ovarian cancer cells. Faulty expression of MSLN plays a role in the multiplication and invasion of tumors.
    When it is overexpressed, mesothelin may induce MAPK, PI3K, and NF-kB pathways. The induction of these pathways plays a part in the metastasis, proliferation, and survival of cancerous cells. Mesothelin also interacts with CA125 to facilitate the implantation of ovarian cancer cells in the peritoneum and the migration of carcinogenic pancreas cells by altering cellular adhesion.

We constructed a BALB/c breast cancer cell line expressing human mesothelin (66C14-M), which was implanted in one or two locations.

    21. findings replicate association between rs1057147 and soluble mesothelin related peptide(SMRP)levels; SMRP performance as diagnostic biomarker for malignant pleural mesothelioma improved by considering genotype rs1057147; this polymorphism most likely affects a binding site for miR-611 PMID: 25436799

    28. A serum mesothelin level is a prognostic indicator for patients with malignant mesothelioma in routine clinical practice. PMID: 25227779
    29. Both the serum CA125(meso) level and the ratio of the serum CA125(mesothelin) to CA125 levels (CA125(mesothelin) /CA125) were significantly higher in patients with EOC. PMID: 25197000
    30. Serum IGFBP2 and MSLN are weak diagnostic classifiers individually, but may be useful in a diagnostic biomarker panel for pancreatic cancer. PMID: 24308545
