结肠癌qBiomarker体细胞突变PCR芯片是一个翻译研究的工具,允许快速、准确、全面的分析在人类结肠癌样本中前体细胞的基因突变:APC,BRAF,CTNNB1 /β-连环蛋白FBXW7, KRAS, PIK3CA, SRC, and P53。这些突变保证广泛的研究,以提高致癌作用的理解和鉴定潜在的药物靶点。已有许多研究通过单个和多个体细胞突变状态信息鉴定关键信号转导中断。例如,EGFR和KRAS基因的突变状态可以预测某些药物针对这些分子的生理反应。人类结肠癌qBiomarker体细胞突变PCR芯片以其全面的内容覆盖范围,用于研究结肠癌背景下的基因突变,有可能发现和鉴定结肠癌和这些突变已确定的其他癌症的药物靶标。这个芯片包含86个DNA突变序列用于检测最频繁的、能性验证、在人类结肠癌症中有生物学意义的突变。这些突变的选择根据全面的体细胞突变数据库和同行评审的科学文献,来自29,000多个结肠癌样本发生最频繁重复编译的体细胞突变。简单的产品模式和操作程序让任何一个具备实时定量PCR仪的实验室都可进行常规的体细胞突变分析。 APC: 34 Assays The most commonly detected APC inactivation mutations are mainly composed of truncation mutations (due to nonsense mutations and frameshift mutations) and point mutations between codons 1250 and 1578. BRAF: 1 Assay In colon cancer, the BRAF mutation that leads to increased kinase activity, p. V600E mutation, is the most important to test. CTNNB1: 5 Assays The most frequently detected CTNNB1/beta-catenin mutations result in abnormal signaling in the WNT signaling pathway. The mutated codons are mainly several serine/threonine residues targeted for phosphorylation by GSK-3beta. FBXW7: 1 Assay The mutations queried by these assays lay in either the third or fourth repeat of the protein's WD40 domain, typically involved in protein-protein interactions. KRAS: 17 Assays The mutation assays include the most frequently occurring mutations in KRAS codons 12, 13, and 61. Mutations at these positions result in reduced intrinsic GTPase activity and/or cause KRAS to become unresponsive to RasGAP. PIK3CA: 7 Assays The most frequently occurring PIK3CA mutations mainly belong to two classes: gain-of-function kinase domain activating mutations and helical domain mutations that mimic activation by growth factors. SRC: 1 Assay SRC is a proto-oncogene and a tyrosine-protein kinase that plays a role in the regulation of embryonic development and cell growth. Mutations in this gene could be involved in the malignant progression of colon cancer. TP53: 20 Assays The most frequently detected somatic mutations in TP53 are largely composed of DNA-binding domain mutations which disrupt either DNA binding or protein structure. 工作原理: Overview of the qBiomarker Somatic Mutation PCR Array / Assay Protocol
