编码细胞P53蛋白的基因突变可能是人类癌症中最常见的遗传损伤类型。这些改变的核心是正常的P53的肿瘤抑制活性的丧失。在许多情况下,这是通过p53的点突变实现的,这通常会导致显著的构象变化。这种突变多肽倾向于在癌细胞中积累到高水平,被认为对共表达的正常p53具有显性的负面影响。对P53的广泛研究,特别是在最近3年的过程中,已经提供了许多关于其作为有效肿瘤抑制因子的生物学和生化机制的见解。现在有许多迹象表明,P53可能在控制细胞增殖、细胞存活和分化方面发挥核心作用。然而,尽管据称P53在这些关键过程中很重要,但在完全缺乏P53的情况下,小鼠的发育显然可以没有任何缺陷。这增加了只有当失去正常生长控制时,p53才可能成为关键限制因素的可能性。-Oren,M.P53:最终的肿瘤抑制基因?FASEB J.6:3169-3176;1992。
Alterations in the gene encoding the cellular p53 protein are perhaps the most frequent type of genetic lesions in human cancer. At the heart of these alterations is the abrogation of the tumor suppressor activity of the normal p53. In many cases this is achieved through point mutations in p53, which often result in pronounced conformational changes. Such mutant polypeptides, which tend to accumulate to high levels in cancer cells, are believed to exert a dominant negative effect over coexpressed normal p53. Extensive research on p53, especially in the course of the last 3 years, has already provided much insight into the biological and biochemical mechanisms that underlie its capacity to act as a potent tumor suppressor. There are now many indications that p53 may play a central role in the control of cell proliferation, cell survival, and differentiation. Nevertheless, despite the purported importance of p53 for such crucial processes, mice can develop apparently without any defect in the total absence of p53. This raises the possibility that p53 may become critically limiting only when normal growth control is lost.— Oren, M. p53: the ultimate tumor suppressor gene?FASEB J.6: 3169‐3176; 1992.
