Historical Background

Mdm2 (murine double minute 2) was first discovered as one of two gene products that were amplified in the spontaneously transformed mouse 3T3-DM cell line (Cahilly-Snyder et al. 1987). Human MDM2 was subsequently cloned by screening a human cDNA library with the mouse Mdm2 probe (Oliner et al. 1992). Mdm2-overexpressing NIH-3T3 and Rat2 fibroblast cells formed tumors when subcutaneously injected into nude mice, indicating the tumorigenic potential of Mdm2 (Fakharzadeh et al. 1991). Supporting this notion, the MDM2 gene was found to be amplified in sarcomas when it was first cloned (Oliner et al. 1992). Similarly, MDM2 overexpression and amplification were observed in other cancer types, including a subset of lymphoma (Watanabe et al. 1996). Later, it was shown that MDM2 formed a complex with p53, suppressing p53’s tumor suppressor functions (Momand et al. 1992; Oliner et al. 1992...
