Nucleophosmin regulates the stability and transcriptional activity of p53
2002年6月24日 · Here we show that NPM interacts directly with the tumour suppressor p53, regulates the increase in stability and transcriptional activation of p53 after different types of stress, and induces...
Tumor Suppressor p53: Biology, Signaling Pathways, and …
TP53 is a gene that encodes for the p53 tumor suppressor protein, commonly referred to as the “Guardian of the Genome” [1]. Its main biological function appears to involve the protection of the DNA integrity of the cell. TP53 plays additional roles …
Targeting p53 pathways: mechanisms, structures and advances in …
2023年3月1日 · Here, we provide a systematic review of the diverse molecular mechanisms of the p53 signaling pathway and how TP53 mutations impact tumor progression. We also discuss key structural features of...
p53: updates on mechanisms, biology and therapy (I) - PMC
In the first volume, we include seven papers that focus on the function and regulation of the wild-type protein. In a highly focused study, Fahreus and colleagues (Karakostis et al., 2019) describe how the interaction of p53 mRNA with the Mdm2 protein opens up new processes by which p53 translation is controlled.
The multiple mechanisms that regulate p53 activity and cell fate
Activated p53 transcriptionally regulates hundreds of genes that are involved in multiple biological processes, including in DNA damage repair, cell cycle arrest, apoptosis and senescence. In the context of DNA damage, p53 is thought to be a decision-making transcription factor that selectively activates genes as part of specific gene ...
Nuclear stabilization of p53 requires a functional nucleolar ...
2022年11月1日 · Using genome-wide loss-of-function screens, we demonstrate the ribosome biogenesis axis as the most potent class of genes whose disruption stabilizes p53. Mechanistically, we identify genes critical for regulation of this pathway, including HEATR3.
Regulation of p53 Function by Formation of Non-Nuclear …
2022年2月18日 · We consider non-nuclear heterologous protein complexes of p53, their structural determinants, regulatory post-translational modifications and the role in intricate p53 functions. The p53 heterologous complexes regulate the folding, trafficking and/or action of interacting partners in cellular compartments.
水泡状胎块中p57、p53及Ki-67的表达及意义
结论:Ki-67和p53的表达对于鉴别水泡状胎块与流产水肿绒毛有重要价值,但对于区别完全性与部分性水泡状胎块其价值有限;而 p57蛋白在CHM和PHM的表达和分布有明显差异,可作为水泡状胎块分型诊断的客观辅助指标。
The multiple mechanisms that regulate p53 activity and cell fate
2019年3月1日 · In this Review, we focus on discussing the established function of p53 as a transcription factor. p53 is activated by cellular stresses including DNA damage, hypoxia, oncogene activation and...
Tumor suppressor p53: Biology, signaling pathways, and ... - PubMed
The p53 pathway is a complex cellular stress response network with multiple diverse inputs and downstream outputs relevant to its role as a tumor suppressor pathway. While inroads have been made in understanding the biology and signaling in the p53 pathway, the p53 family, transcriptional readouts, and effects of an array of mutants, the ...
