p53 tumour suppressor
Other speculated functions include1⁄4 does it really need more? Well, it seems to function in multicellular development and differentiation, too, and there’s some evidence that it’s an exonuclease. If you’re beginning to think that researchers from all areas of biology are obsessed with p53, witness the number of grant applications claiming that studies of p53 will provide a cure for cancer, ex...
متن کاملp53 tumour suppressor gene expression in pancreatic neuroendocrine tumour cells.
Neuroendocrine pancreatic tumours grow slower and metastasise later than ductal and acinar carcinomas. The expression of the p53 tumour suppressor gene in pancreatic neuroendocrine tumour cells is unknown. Pancreatic neuroendocrine cell lines (n = 5) and human tumour tissues (n = 19) were studied for changed p53 coding sequence, transcription, and translation. Proliferative activity of tumour c...
متن کاملIdentification of p53-target genes in Danio rerio
To orchestrate the genomic response to cellular stress signals, p53 recognizes and binds to DNA containing specific and well-characterized p53-responsive elements (REs). Differences in RE sequences can strongly affect the p53 transactivation capacity and occur even between closely related species. Therefore, the identification and characterization of a species-specific p53 Binding sistes (BS) c...
متن کاملIdentification of novel p53 target genes in ionizing radiation response.
The tumor suppressor p53 plays an essential role in cellular adaptation to stress. In response to ionizing radiation, p53 regulates the transcription of genes in a diverse set of pathways including DNA repair, cell cycle arrest, and apoptosis. Previously, we identified by microarray analysis a set of genes that are transcriptionally activated or repressed in response to radiation exposure. In t...
متن کاملRegulation of p53 tumour suppressor target gene expression by the p52 NFB subunit
The p52/p100 nuclear factor kappa B (NF-jB) subunit (NF-jB2) is aberrantly expressed in many tumour types and has been implicated as a regulator of cell proliferation. Here, we demonstrate that endogenous p52 is a direct regulator of Cyclin D1 expression. However, stimulation of Cyclin D1 expression alone cannot account for all the cell cycle effects of p52/p100 and we also find that p52 repres...
