The p53 and MDM2 genes were analyzed in 24 human soft tissue sarcomas (11 malignant fibrous histiocytomas and 13 liposarcomas). Alterations of p53, consisting of point mutations, deletions, or overexpression, were detected in one-third (8 of 24) of the sarcomas.

The human homologue of the murine double minute 2 gene (MDM2), a p53-binding protein which may act as a regulator of p53 protein function, has recently been cloned. Initial studies of this gene in a variety of human tumors have

A cellular phosphoprotein with an apparent molecular mass of 90 kd (p90) that forms a complex with both mutant and wild-type p53 protein has been characterized, purified, and identified. The protein was identified as a product of the murine double

This study investigates the mdm2 gene status and expression in 66 surgically resected human breast carcinomas, with correlations with clinico-pathological and biological data (histological type, grading, steroid receptor status, p53 expression, proliferative activity). Four (7.7 per cent) out of 52
J D Oliner et al.
Nature, 362(6423), 857-860 (1993-04-29)
The tumour-suppressor gene p53 is inactivated in most human malignancies either by missense mutations or by binding to oncogenic proteins. In human soft tissue sarcomas, inactivation apparently results from MDM2 gene amplification. MDM2 is an oncogene product that may function
