TLDR
DNA clones of the wild-type p53 proto-oncogene inhibit the ability of E1Aplus ras or mutant p53 plus ras-activated oncogenes to transform primary rat embryo fibroblasts, suggesting that the p53 prototype can act negatively to block transformation.About:

A genetic model for colorectal tumorigenesis
Eric R. Fearon,Bert Vogelstein +1 more
TL;DR: A model for the genetic basis of colorectal neoplasia that includes the following salient features is presented, which may be applicable to other common epithelial neoplasms, in which tumors of varying stage are more difficult to study.

p53 mutations in human cancers
TL;DR: The p53 mutational spectrum differs among cancers of the colon, lung, esophagus, breast, liver, brain, reticuloendothelial tissues, and hemopoietic tissues as mentioned in this paper.

Mice deficient for p53 are developmentally normal but susceptible to spontaneous tumours
Lawrence A. Donehower,Michele Harvey,Betty L. Slagle,Mark J. McArthur,Charles A. Montgomery,Janet S. Butel,Allan Bradley +6 more
TL;DR: Observations indicate that a normal p53 gene is dispensable for embryonic development, that its absence predisposes the animal to neoplastic disease, and that an oncogenic mutant form of p53 is not obligatory for the genesis of many types of tumours.
Journal ArticleDOI
The E6 oncoprotein encoded by human papillomavirus types 16 and 18 promotes the degradation of p53
TL;DR: It is demonstrated that the E6 proteins of the oncogenic HPVs that bind p53 stimulate the degradation of p53, which results in selective degradation of cellular proteins such as p53 with negative regulatory functions provides a novel mechanism of action for dominant-acting oncoproteins.
Journal Article
Participation of p53 Protein in the Cellular Response to DNA Damage
TL;DR: A role for the wild-type p53 protein in the inhibition of DNA synthesis that follows DNA damage is suggested and a new mechanism for how the loss of wild- type p53 might contribute to tumorigenesis is suggested.

A new technique for the assay of infectivity of human adenovirus 5 DNA.
Frank L. Graham,A. J. Van Der Eb +1 more
TL;DR: A new technique for assaying infectivity of adenovirus 5 DNA has been developed and a reproducible relationship between amounts of DNA inoculated per culture and numbers of plaques produced was demonstrated.

A human DNA segment with properties of the gene that predisposes to retinoblastoma and osteosarcoma
Stephen H. Friend,Stephen H. Friend,René Bernards,Snezna Rogelj,Robert A. Weinberg,Joyce M. Rapaport,Daniel M. Albert,Thaddeus P. Dryja +7 more
TL;DR: The isolation of a complementary DNA segment that detects a chromosomal segment having the properties of the gene at this locus is described, which is expressed in many tumour types, but no RNA transcript has been found in retinoblastomas and osteosarcomas.
Journal ArticleDOI
Tumorigenic conversion of primary embryo fibroblasts requires at least two cooperating oncogenes.
TL;DR: The embryo fibroblasts become tumorigenic if a second oncogene such as a viral or cellular myc gene or the gene for the polyoma large-T antigen is introduced together with the ras gene.

Transformation of mammalian cells to antibiotic resistance with a bacterial gene under control of the SV40 early region promoter.
Peter Southern,Paul Berg +1 more
TL;DR: A bacterial gene conferring resistance to neomycin-kanamycin antibiotics has been inserted into SV40 hybrid plasmid vectors and introduced into cultured mammalian cells by DNA transfusion and it is shown that cell transformation to G418 resistance is an efficient means for cotransformation of nonselected genes.

T Antigen Is Bound to a Host Protein in Sv40-Transformed Cells
TL;DR: It is reported here that the T antigen in a line of SV40-transformed mouse cells forms an oligomeric complex with a specific cell coded protein.
