Ras oncogene mutations in benign and malignant thyroid neoplasms.

Abstract excerpt

Current models for tumorigenesis propose that a series of genetic alterations occur during the progression from the normal cell to the malignant phenotype. Mutations in each of the three ras genes (K-ras, H-ras, and N-ras) have been identified in many human neoplasms, including thyroid cancer. In this study we examined genomic DNA from benign and malignant thyroid neoplasms for mutations that are known to...
