Eflornithine 82-86 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 116-120 23440295-0 2013 DFMO/eflornithine inhibits migration and invasion downstream of MYCN and involves p27Kip1 activity in neuroblastoma. Eflornithine 0-4 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 64-68 23440295-0 2013 DFMO/eflornithine inhibits migration and invasion downstream of MYCN and involves p27Kip1 activity in neuroblastoma. Eflornithine 5-17 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 64-68 23440295-5 2013 DFMO treatment leads to the accumulation of the cyclin-dependent kinase inhibitor p27(Kip1) protein and causes p27(Kip1)/Rb-coupled G(1) cell cycle arrest in MYCN-amplified NB tumor cells through a process that involves p27(Kip1) phosphorylation at residues Ser10 and Thr198. Eflornithine 0-4 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 158-162 23440295-8 2013 DFMO treatments induced MYCN protein downregulation and phosphorylation of Akt/PKB (Ser473) and GSK3-beta (Ser9), and polyamine supplementation alleviated the DFMO-induced effects. Eflornithine 0-4 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 24-28 19147568-5 2009 Here, we report that DFMO treatment, but not Odc heterozygosity, impairs MYCN-induced neuroblastoma and that, in this malignancy, transient DFMO treatment is sufficient to confer protection. Eflornithine 21-25 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 73-77 19147568-6 2009 The selective anticancer effects of DFMO on mouse and human MYCN-amplified neuroblastoma also rely on its ability to disable the proliferative response of Myc, yet in this tumor context, DFMO targets the expression of the p21(Cip1) Cdk inhibitor, which is also suppressed by Myc oncoproteins. Eflornithine 36-40 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 60-64 19147568-6 2009 The selective anticancer effects of DFMO on mouse and human MYCN-amplified neuroblastoma also rely on its ability to disable the proliferative response of Myc, yet in this tumor context, DFMO targets the expression of the p21(Cip1) Cdk inhibitor, which is also suppressed by Myc oncoproteins. Eflornithine 187-191 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 60-64 19147568-7 2009 These findings suggest that agents, such as DFMO, that target the polyamine pathway may show efficacy in high-risk, MYCN-amplified neuroblastoma. Eflornithine 44-48 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 116-120 34129075-8 2021 Excised tumors revealed that DFMO/probenecid treatment decreases polyamines putrescine and spermidine, reduces MYCN protein levels and dephosphorylates retinoblastoma (Rb) protein (p-RbSer795), suggesting DFMO/probenecid-induced cell cycle arrest. Eflornithine 29-33 MYCN proto-oncogene, bHLH transcription factor Homo sapiens 111-115 34129075-8 2021 Excised tumors revealed that DFMO/probenecid treatment decreases polyamines putrescine and spermidine, reduces MYCN protein levels and dephosphorylates retinoblastoma (Rb) protein (p-RbSer795), suggesting DFMO/probenecid-induced cell cycle arrest.
