Amplification of Both C-myc and C-raf-1 Oncogenes in a Human Osteosarcoma
Overview
Affiliations
Fourteen human bone and soft part tumor tissues were screened by Southern blot hybridization using five oncogene probes (c-myc, c-K-ras, c-fos, c-raf-1, and N-myc). Amplification of c-myc was found in two osteosarcomas and one malignant fibrous histiocytoma. One of these osteosarcomas had amplified c-raf-1 gene. Rearrangement of the amplified gene was not observed. This is the first report of c-raf-1 amplification in human cancer tissues.
