TL;DR: The p53 pathway is critical for tumor suppression, as the majority of human cancer has a faulty p53, and a novel p53-RNPC1 autoregulatory loop is identified, suggesting that RNPC1 plays a role in tumorigenesis by repressing p53 translation.
Journal ArticleDOI
RNPC1 modulates the RNA-binding activity of, and cooperates with, HuR to regulate p21 mRNA stability.
TL;DR: The ability of RNPC1 to regulate p21 mRNA stability is dependent on HuR, and the RNA-binding activity of HuR to p21 transcript was enhanced byRNPC1 in vitro and in vivo.
Journal ArticleDOI
RNPC1, an RNA-binding protein and a target of the p53 family, regulates p63 expression through mRNA stability.
TL;DR: This work found that RNPC1, a RNA-binding protein and a target of the p53 family, regulates p63 mRNA stability and consequently p63 activity, and uncovered a previously undetected mechanism by which p63 expression is regulated via RNA stability and a novel regulatory feedback loop betweenRNPC1 and p63.
Journal ArticleDOI
The cyclin-dependent kinase inhibitor p21 is regulated by RNA-binding protein PCBP4 via mRNA stability
TL;DR: It is revealed that PCBP4 regulates both basal and stress-induced p21 expression through binding p21 3′-UTR and modulating p21 mRNA stability, and it is uncovered thatPCBP4 binds to the 3′ -UTR of p21 transcript in vitro and in vivo to regulate p21 RNA stability.
Journal ArticleDOI
Mutant p53 Protein Is Targeted by Arsenic for Degradation and Plays a Role in Arsenic-mediated Growth Suppression
TL;DR: It is found that wild type p53 is induced by arsenic trioxide in tumor cells, consistent with published studies, and arsenic compounds degrade both endogenous and ectopically expressed mutant p53 in time- and dose-dependent manners, which provides an insight into exploring arsenic compound-based therapy for tumors harboring a mutants p53.
