英文摘要 | KRAS mutations exhibit significant predictive and prognostic value in cancer. Efficient, sensitive, and accurate molecular approaches are required to evaluate KRAS mutation status, even when mutant alleles are restricted to a small portion of a clinical sample, which otherwise contains wild-type alleles. We describe a highly sensitive method to detect KRAS mutations by high-resolution melting (HRM) analysis after mutation enrichment by fast-COLDpolymerase chain reaction (PCR). Using 10 ng of starting DNA and after fast-COLD-PCR of a 76-bp region containing KRAS codons 12 and 13; the amplicons undergo a nested conventional PCR reaction followed by HRM analysis. Samples exhibiting aberrant melting profiles are sequenced to identify mutation type and position. Serial dilution experiments indicate a sensitivity of approximately 0.3% mutant-to-wild type for HRM-based mutation detection and the ability to directly sequence mutation-containing samples. A number of lung adenocarcinoma specimens earlier characterized were screened. Fast-COLD-PCR-HRM analysis correctly identified KRAS mutations and also showed a previously undetected, low-level missense GGT > TTT complex mutation. On account of the short target regions and low requirement of starting DNA, this rapid, cost-effective, and sensitive fast-COLD-PCR-HRM approach is expected to find broad application for detecting low-abundance KRAS mutations in a wide range of clinical specimens. |
