Das p53-Protein spielt eine zentrale Rolle bei der Expression von Genen, die an der Regulierung der Apoptose und der DNA-Reparatur beteiligt sind. Im Jahre 1992 wurde ihm der Name Wächter des Genoms (Lane, 1992) verliehen. 1993 wurde es zum Molekül des Jahres gekürt Somatic mutations in the TP53 gene are one of the most frequent alterations in human cancers, and germline mutations are the underlying cause of Li-Fraumeni syndrome, which predisposes to a wide spectrum of early-onset cancers. Most mutations are single-base substitutions distributed throughout the coding sequence The TP53-inducible glycolysis and apoptosis regulator (TIGAR) also known as fructose-2,6-bisphosphatase TIGAR is an enzyme that in humans is encoded by the C12orf5 gene. TIGAR is a recently discovered enzyme that primarily functions as a regulator of glucose breakdown in human cells The standard classification used to define the various cancer genes confines tumor protein p53 (TP53) to the role of a tumor suppressor gene. However, it is now an indisputable fact that many p53.. TP53 is a member of a broader gene family including TP63 and TP73. Unlike TP53, both TP63 and TP73 do not have tumour suppressive capa-bilities. In eukaryotes, the p53 protein sequence is relatively conserved; however, TP53 has evolved by increasing gene dosage

Li-Fraumeni syndrome (LFS) LFS is a rare, autosomal dominant cancer predisposition syndrome which often occurs at a young age. Individuals with LFS have an estimated 60% chance of malignancy by age 45 and a 95% chance by age 70. LFS is diagnosed in individuals meeting established.

One gene that is often damaged during an animal's lifetime is called TP53. This gene normally produces a tumor suppressor protein that senses when DNA is damaged or a cell is under stress and either briefly slows the cell's growth while the damage is repaired or triggers cell death if the stress is overwhelming TP53 is a gene that helps stop the growth of tumors. It's known as a tumor suppressor. A tumor suppressor gene works like the brakes on a car. It puts the brakes on cells, so they don't divide too quickly Mutations in the TP53 gene are the most commonly acquired mutations in cancer. The p53 protein, made by the TP53 gene, normally acts as the supervisor in the cell as the body tries to repair.

Variations in the TP53 gene have been suggested to play a role in many cancers, including breast. We previously observed an association between TP53 haplotypes based on four polymorphisms (rs17878362, rs1042522, rs12947788, and rs17884306) and the risk of colorectal and pancreatic cancer. Based on these results, in the present study, we have investigated the same polymorphisms and their. TP53. gene. p53 protein. The p53 protein prevents cells with damaged DNA from dividing or, when damage is too great, promotes cell death. The primary structure of the protein is the sequence of amino acids linked together in a polypeptide chain; groups of amino acids, called domains, have specific functions, such as the binding of DNA TP53 is a gene that codes for a protein called p53 that plays an important role in cell cycle control and functions as a tumor suppressor. The name is due to its molecular mass: it is in the 53 kilodalton fraction of cell proteins. In normal cells, the p53 protein level is low Alternatives Spleißen des TP53-Gens (s.u.

TP53 is a 'cancer protection' gene that helps to protect against many types of cancer. Everyone has two TP53 genes (one from their mother, and one from their father). If one of the genes is not working, this is known as having a faulty TP53 gene, or a TP53 mutation TP53 is a tumor suppressor gene that is named after, and provides instructions for making, a protein called tumor protein 53 (TP53). Through the effect of the protein that it produces, TP53 is a tumor suppressor gene, which means that it regulates the cycle of cell division by keeping cells from growing and dividing too fast or in an uncontrolled way TP53-mediated regulation probably ensures increased protein level of DNA repair genes under genotoxic stress. TP53 directly stimulates transcription of several genes involved in DNA mismatch repair, including MSH2 (Scherer et al. 2000, Warnick et al. 2001), PMS2 and MLH1 (Chen and Sadowski 2005). TP53 also directly stimulates transcription of DDB2, involved in nucleotide excision repair (Tan. TP53 (which encodes p53) is one of the most frequently mutated genes in cancers. In this study, we generated TP53-mutant pigs by gene editing via electroporation of the Cas9 protein (GEEP), a process that involves introducing the Cas9 protein and single-guide RNA (sgRNA) targeting exon 3 and intron 4 of TP53 into in vitro-fertilized zygotes
