摘要:
A method for gene therapy for cancers wherein chromosomal location of an inactive or defective cancer suppressing gene is established, a replacement gene which is preferably cloned is then used to replace the inactive or defective cancer suppressing gene in the chromosome. In addition to its uses in therapy, the present invention provides a means for prophylactically treating individuals having a genetic predisposition to cancer and provides an animal model for testing for carcinogenicity of environmental substances.

摘要:
The retinoblastoma protein (Rb) is the product of the retinoblastoma gene and has been found to contain mutations in retinoblastoma tumor cells. Two nuclear proteins that bind to Rb, p48 and p46 have been isolated and the genes have been cloned. These proteins bind to Rb competitively with the SV40 T antigen. p48 is shown to suppress heat shock sensitive Ras mutations in yeast and is implicated as a modulator of the retinoblastoma suppressor function of Rb.
