WebApr 11, 2024 · This approach showed that MG132 treatment increased steady-state levels of p53 and p53-S376p in the cytoplasmic fraction of H1299 cells expressing p53 wild-type and VprBP, whereas there was no ... WebIntroduction. TP53 is possibly the most frequently altered gene in human cancers (Kandoth et al., 2013).The encoded p53 protein is a powerful tumor suppressor, and its loss-of-function is associated with cancer development and progression (Levine, 2024).Intriguingly, the majority of TP53 mutations are missense, encoding full-length proteins (mutp53) that …

In mammals, Synoviolin plays crucial roles in various physiological and p... WebCytoplasmic p53 associates with the microtubule cytoskeleton and the dynein family of motor proteins; while Parc and mot2 are involved in its cytoplasmic sequestration. …
WebThe p53 cytoplasmic pattern predominantly consisted of weak to moderate cytoplasmic staining in >95% of tumor cells as well as variable intensity nuclear staining involving a range of just a few cells to just under 80% of tumor cells. WebApr 19, 2011 · p53 is a transcription factor that regulates a variety of target genes. It is usually rapidly degraded by the proteasome but stabilized on DNA damage or cellular stress. Because ASPP2 recruits cytoplasmic p53 on Hp infection, we hypothesized that the transcriptional activity of p53 might be altered on translocation of CagA.
WebFeb 20, 2004 · The tumor suppressor p53 regulates cellular responses to stress by serving in the nucleus to regulate transcription of genes involved in processes including cell cycle arrest, DNA repair, and apoptosis.
WebJan 9, 2024 · To identify novel proteins that interact with the fragile X mental retardation protein (FMRP), encoded by the FMR1 gene (), Schenck et al.
