When mutants gain new powers: news from the mutant p53 field
Ample data indicate that mutant p53 proteins not only lose their tumour suppressive functions, but also gain new abilities that promote tumorigenesis. Moreover, recent studies have modified our view… Expand
Mutant p53 gain-of-function in cancer.
In its wild-type form, p53 is a major tumor suppressor whose function is critical for protection against cancer. Many human tumors carry missense mutations in the TP53 gene, encoding p53. Typically,… Expand
PACT: cloning and characterization of a cellular p53 binding protein that interacts with Rb
Cellular functions of tumor suppressor proteins can be mediated by protein-protein interactions. Using p53 as a probe to screen an expression library, a cDNA encoding a 250 kDa protein was isolated.… Expand
Oncogenic mutations of the p53 tumor suppressor: the demons of the guardian of the genome.
The p53 guardian of the genome is inactivated in the majority of cancers, mostly through missense mutations that cause single residue changes in the DNA binding core domain of the protein. Not only… Expand
Mutations in the p53 Tumor Suppressor Gene: Important Milestones at the Various Steps of Tumorigenesis.
Inactivation of the p53 tumor suppressor is a frequent event in tumorigenesis. In most cases, the p53 gene is mutated, giving rise to a stable mutant protein whose accumulation is regarded as a… Expand
Modulation of the vitamin D3 response by cancer-associated mutant p53.
The p53 gene is mutated in many human tumors. Cells of such tumors often contain abundant mutant p53 (mutp53) protein, which may contribute actively to tumor progression via a gain-of-function… Expand

This study demonstrated the involvement of the tumor suppressor protein p53 in differentiation and programmed cell death of neurons and oligodendrocytes, two cell types that leave the mitotic cycle… Expand
'Cancer associated fibroblasts'--more than meets the eye.
Cancer associated fibroblasts (CAFs) are a subpopulation of cells that reside within the tumor microenvironment and promotes the transformation process by encouraging tumor growth, angiogenesis,… Expand
Mutant p53 prolongs NF-κB activation and promotes chronic inflammation and inflammation-associated colorectal cancer.
The tumor suppressor p53 is frequently mutated in human cancer. Common mutant p53 (mutp53) isoforms can actively promote cancer through gain-of-function (GOF) mechanisms. We report that mutp53… Expand
TMPRSS2/ERG Promotes Epithelial to Mesenchymal Transition through the ZEB1/ZEB2 Axis in a Prostate Cancer Model
Prostate cancer is the most common non-dermatologic malignancy in men in the Western world. Recently, a frequent chromosomal aberration fusing androgen regulated TMPRSS2 promoter and the ERG gene… Expand
