qBiomarker Somatic Mutation PCR Array: Human Lung Cancer
The Human Lung Cancer qBiomarker Somatic Mutation PCR Array is a translational research tool that allows rapid, accurate, and comprehensive profiling of the top somatic mutations in human lung cancer samples in the following genes: AKT1, BRAF, CTNNB1/beta-catenin, EGFR, ERBB2, HRAS, KRAS, NRAS, PIK3CA, LKB1/STK11, and P53. These mutations warrant extensive investigation to enhance the understanding of carcinogenesis and identify potential drug targets. Numerous research studies have demonstrated the utility of individual and multiple somatic mutation status information in identifying key signaling transduction disruptions. For example, the mutation status of the EGFR and KRAS genes can predict the physiological response to certain drugs targeting these molecules. The Human Lung Cancer qBiomarker Somatic Mutation PCR Array, with its comprehensive content coverage, is designed for the study of mutations in the context of lung cancer and has the potential for discovery and verification of drug target biomarkers for this cancer type and other cancer types in which these mutations have been identified. This array includes 83 DNA sequence mutation assays designed to detect the most frequent, functionally verified, and biologically significant mutations in human lung cancer. These mutations were chosen from curated, comprehensive somatic mutation databases and peer-reviewed scientific literature, and represent the most frequently recurring somatic mutations compiled from over 13000 lung cancer samples. The simplicity of the product format and operating procedure allows routine somatic mutation profiling in any research laboratory with access to real-time PCR instruments.

AKT1: 1 Assay
The mutation assay detects the best known AKT1 mutation, c.49G>A, p.E17K. This is a PH domain mutation that results in constitutive targeting of AKT1 to plasma membrane.
BRAF: 4 Assays
There are two major classes of BRAF mutations. One class leads to increased BRAF kinase activity, such as the p. V600E mutation. The other class leads to impaired kinase activity, such as the p.G469A mutation.
CTNNB1: 2 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.
EGFR: 22 Assays
The most frequently identified EGFR mutations include P-loop and activation loop point mutations, kinase domain deletions, and insertion mutations.
ERBB2: 2 Assays
The most frequently identified ERBB2 activating mutations cluster in the ERBB2 kinase domain region.
HRAS: 1 Assay
The most important HRAS mutation in lung cancer occurs at codon 61.
KRAS: 13 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.
NRAS: 1 Assay
The most important NRAS mutation in lung cancer occurs at codon 61.
PIK3CA: 2 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.
STK11: 2 Assays
The most commonly detected STK11/LKB1 inactivation mutations are mainly due to truncation or point mutations.
TP53: 33 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.
