Abstract

AbstractMutations within the tumor suppressor genes Rb‐1 and p53 are commonly found in many human malignancies, and loss of wild‐type function of both p53 and RB appear to be important events in the development of these malignancies. Interference with normal RB and p53 function in the cell has apparently also been exploited by the oncogenic genital human papillomaviruses (HPVs), which encode transforming proteins capable of binding cellular RB and p53 proteins. We have investigated the expression of RB and p53 in a series of eight cervical carcinoma cell lines, six of which contain HPV sequences and two of which have arisen apparently independently of HPV infection. In the six HPV‐positive lines, no evidence of abnormal RB or p53 protein could be detected. However, there was evidence for abnormal RB and p53 in the two HPV–negative lines. These data are consistent with the hypothesis that loss of wild‐type RB and p53 function is necessary for tumor development and that such loss can occur either by mutation within the cellular gene or by expression of viral proteins capable of complexing wild‐type cellular proteins.
