Oncogenomic Approaches in Exploring Gain of Function of Mutant p53
Cancer is caused by the spatial and temporal accumulation of alterations in the genome of a given cell. This leads to the deregulation of key signalling pathways that play a pivotal role in the control of cell proliferation and cell fate. The p53 tumor suppressor gene is the most frequent target in genetic alterations in human cancers. The primary selective advantage of such mutations is the el...
متن کاملMutant 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, the affected tumor cells accumulate excessive amounts of the mutant p53 protein. Various lines of evidence indicate that, in addition to abrogating the tumor suppressor functions of wild-type p53, t...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولPla2g16 phospholipase mediates gain-of-function activities of mutant p53.
p53(R172H/+) mice inherit a p53 mutation found in Li-Fraumeni syndrome and develop metastatic tumors at much higher frequency than p53(+/-) mice. To explore the mutant p53 metastatic phenotype, we used expression arrays to compare primary osteosarcomas from p53(R172H/+) mice with metastasis to osteosarcomas from p53(+/-) mice lacking metastasis. For this study, 213 genes were differentially exp...
متن کاملp53 from complexity to simplicity: mutant p53 stabilization, gain-of-function, and dominant-negative effect.
Increasing the complexity of their models, p53s are stabilized either in order to function (wt p53) or due to the loss of function (mutant p53) with acquiring a mysterious prion-like ability to drive the normal p53 into the abnormal conformation to gain new functions. As already recognized, the loss of trans-activating function leads to a stabilization of mutant p53 because of the disappearance...
