Tretinoin 24-37 S-phase kinase associated protein 2 Homo sapiens 126-130 19035179-6 2008 Western blot displayed that ATRA could decrease the expression of cyclin A, up-regulate the expression of p21 and p27, and down-regulate the expression of p27 related proteins Skp2. Tretinoin 28-32 S-phase kinase associated protein 2 Homo sapiens 176-180 18212744-8 2008 Thus, retinoic acid downregulates Rae1, hence facilitating APC(Cdh1)-mediated Skp2 degradation leading to the arrest of cell cycle progression and neuroblastoma differentiation. Tretinoin 6-19 S-phase kinase associated protein 2 Homo sapiens 78-82 18212744-2 2008 However, the mechanism responsible for retinoic acid-mediated Skp2 destabilization is unknown. Tretinoin 39-52 S-phase kinase associated protein 2 Homo sapiens 62-66 18212744-4 2008 We found that retinoic acid induced the nuclear accumulation of Cdh1 that paralleled Skp2 destabilization and p27 accumulation. Tretinoin 14-27 S-phase kinase associated protein 2 Homo sapiens 85-89 12700651-0 2003 Retinoic acid decreases targeting of p27 for degradation via an N-myc-dependent decrease in p27 phosphorylation and an N-myc-independent decrease in Skp2. Tretinoin 0-13 S-phase kinase associated protein 2 Homo sapiens 149-153 15735731-0 2005 Retinoic acid stabilizes p27Kip1 in EBV-immortalized lymphoblastoid B cell lines through enhanced proteasome-dependent degradation of the p45Skp2 and Cks1 proteins. Tretinoin 0-13 S-phase kinase associated protein 2 Homo sapiens 138-145 15735731-3 2005 Furthermore, we demonstrate that RA downregulates the expression of the p45Skp2 and Cks1 proteins, two essential components of the SCF(Skp2) ubiquitin ligase complex that target p27Kip1 for degradation. Tretinoin 33-35 S-phase kinase associated protein 2 Homo sapiens 72-79 15735731-3 2005 Furthermore, we demonstrate that RA downregulates the expression of the p45Skp2 and Cks1 proteins, two essential components of the SCF(Skp2) ubiquitin ligase complex that target p27Kip1 for degradation. Tretinoin 33-35 S-phase kinase associated protein 2 Homo sapiens 75-79 15735731-5 2005 Moreover, overexpression of p45Skp2 in DG75 cells prevents p27Kip1 protein accumulation and promotes resistance to the antiproliferative effects of RA. Tretinoin 148-150 S-phase kinase associated protein 2 Homo sapiens 28-35 15735731-9 2005 These results indicate that downregulation of p45Skp2 is a key element underlying RA-induced p27Kip1 stabilization in B cells, resulting in an impaired targeting of the protein to the ubiquitin-proteasome pathway and probably contributing to the nuclear accumulation of p27Kip1. Tretinoin 82-84 S-phase kinase associated protein 2 Homo sapiens 46-53 12700651-10 2003 However, RA also decreases Skp2 levels thus impairing the ability of p27 to be ubiquitinated. Tretinoin 9-11 S-phase kinase associated protein 2 Homo sapiens 27-31 34921867-6 2022 KEY FINDINGS: We report that the progression of APL and the attenuation of APL sensitivity to ATRA are positively associated with Skp2. Tretinoin 94-98 S-phase kinase associated protein 2 Homo sapiens 130-134 34921867-8 2022 Coupled with ATRA or GSK3beta inhibitor treatment, genetic or pharmacological inhibition of Skp2 strikingly induces JunB expression by accelerating the degradation of PML-RARalpha, which contributes to the eradication of APL. Tretinoin 13-17 S-phase kinase associated protein 2 Homo sapiens 92-96 11595732-0 2001 Retinoic acid-mediated growth arrest requires ubiquitylation and degradation of the F-box protein Skp2. Tretinoin 0-13 S-phase kinase associated protein 2 Homo sapiens 98-102 11595732-5 2001 Furthermore, we demonstrate that ATRA promotes the ubiquitylation of Skp2, an F-box protein that targets p27 for degradation. Tretinoin 33-37 S-phase kinase associated protein 2 Homo sapiens 69-73 11595732-8 2001 We found that the mechanism of ATRA-induced ubiquitylation of cyclin D1 and Skp2 is independent of CUL-1 expression and that ATRA can rescue cyclin D1 degradation in the uterine cell line SK-UT-1, where D-type cyclins are stabilized due to a specific defect in proteolysis. Tretinoin 31-35 S-phase kinase associated protein 2 Homo sapiens 76-80 11595732-9 2001 These data suggest that ATRA induces a novel pathway of ubiquitylation and that the degradation of the F-box protein Skp2 is the mechanism underlying p27 accumulation and cyclin E-cdk2 inactivation following ATRA treatment. Tretinoin 24-28 S-phase kinase associated protein 2 Homo sapiens 117-121 11595732-9 2001 These data suggest that ATRA induces a novel pathway of ubiquitylation and that the degradation of the F-box protein Skp2 is the mechanism underlying p27 accumulation and cyclin E-cdk2 inactivation following ATRA treatment.
