  • 产品描述:
    人Dickkopf相关蛋白2(DKK2)酶联免疫试剂盒(CSB-EL006921HU)为双抗夹心法ELISA试剂盒,定量检测血清、血浆、组织匀浆、细胞裂解物样本中的DKK2含量。DKK2,全称dickkopf WNT signaling pathway inhibitor 2,是一种分泌蛋白,能够抑制β-联蛋白介导的Wnt信号传导,并具有促血管生成活性。其在多种肿瘤组织中表达上调,通过抑制杀伤性免疫细胞激活和减弱肿瘤血管生成来抑制肿瘤形成。研究显示,DKK2的抑制作用与CD8+细胞毒性T淋巴细胞(CTL)活性和肿瘤血管生成减弱有关,是治疗癌症的有希望靶点。试剂盒检测范围为0.312 ng/mL-20 ng/mL,适用于体外培养细胞模型、动物组织或体液样本的DKK2蛋白定量研究;为探索Wnt信号通路在癌症、骨疾病、干细胞分化等领域的分子机制提供可靠工具,满足基础科研中对蛋白表达动态分析的需求。本品仅用于科研,不用于临床诊断,产品具体参数及操作步骤详见产品说明书。

靶点详情

  • 功能:
    Antagonizes canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt and by forming a ternary complex with the transmembrane protein KREMEN that promotes internalization of LRP5/6. DKKs play an important role in vertebrate development, where they locally inhibit Wnt regulated processes such as antero-posterior axial patterning, limb development, somitogenesis and eye formation. In the adult, Dkks are implicated in bone formation and bone disease, cancer and Alzheimer disease.

    1. our findings demonstrate that DKK2 functions as a tumor suppressor through inhibiting cell proliferation and inducing apoptosis via regulating Wnt signaling during breast tumorigenesis. PMID: 28467796
    2. Knock down of the dickkopf WNT signaling pathway inhibitor 2 (DKK2) resulted in a significant suppression of HOXD10, HOXD11 and HOXD13 while over-expression of DKK2 and stimulation with factors of the WNT signaling pathway. PMID: 27363011
    3. epigenetic silencing of Wnt antagonists was associated with gastric carcinogenesis, and concurrent hypermethylation of SFRP2 and DKK2 could be a potential marker for a prognosis of poor overall survival. PMID: 28152305
    4. the genotyping and functional findings are consistent with the hypothesis that DKK2 is a tumor suppressor; by selectively retaining a transcriptionally inactive DKK2 allele, the reduction of DKK2 function results in unchecked Wnt/beta-catenin signaling, contributing to hepatocellular carcinoma oncogenesis. PMID: 27203079
    5. The present report suggested that DKK2 downregulation suppressed the proliferation and invasion of prostate cancer cells by inhibiting the Wnt/betacatenin signaling pathway. PMID: 27431620
    6. these findings reveal that the miR-187-5p-DKK2 pathway regulates Wnt/beta-catenin signaling, cell growth, and apoptosis. Our findings provide the first evidence of a role for miR-187-5p in promotion of B-cell ALL. PMID: 27296949

    16. In the study of the genetics of alcoholism, three SNPs in DKK2 (rs427983; rs419558; rs399087) demonstrated empirical significance. PMID: 20332099
    17. DKK2 is epigenetically silenced by methylation in higher grades and stages of renal cell carcinoma; results suggest that DKK2 inhibits renal cancer progression through apoptotic and cell cycle pathways PMID: 19755393
    18. Analysis of individual Dkk domains and chimeric Dkks shows that the carboxy-terminal domains of both Dkk1 & 2 associate with LRP6 and are necessary and sufficient for Wnt8 inhibition. PMID: 12167704
