title: No association between c-myc amplification and TP53 mutation in sarcoma tumorigenesis.
abstract: Oncogenes and tumor suppressor genes coparticipate in sarcoma tumorigenesis. We tested 43 sarcomas for c-myc amplification by Southern blot and molecular hybridization techniques and TP53 mutations by the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) technique and direct sequencing of the PCR products. We found eight tumors with c-myc amplification and five different tumors with TP53 mutations but no tumors harbor both c-myc and TP53 alterations. We suggest that c-myc amplification and TP53 mutations do not seem to coparticipate in the tumorigenesis of sarcomas.
