2 The present study aimed to investigate the pathway related to MCL1 expression in ABT-263-treated human leukemia U937 cells. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid MCL1 apoptosis regulator, BCL2 family member Homo sapiens
3 ABT-263 upregulated MCL1 protein expression but did not affect its mRNA level and protein stability. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid MCL1 apoptosis regulator, BCL2 family member Homo sapiens
4 Overexpression of 4EBP1 abrogated ABT-263-induced MCL1 upregulation. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid MCL1 apoptosis regulator, BCL2 family member Homo sapiens
5 Inhibition of the IKKalpha/beta-NFkappaB axis or autophagy mitigated the effect of ABT-263 on 4EBP1 and MCL1 expression. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid MCL1 apoptosis regulator, BCL2 family member Homo sapiens
6 Our data indicate that ABT-263 alleviates the inhibitory effect of 4EBP1 on MCL1 protein synthesis through IKKalpha/beta-NFkappaB-mediated induction of autophagy, and suggest a promising strategy to improve anti-leukemia therapy with ABT-263. 2,2'-azino-di-(3-ethylbenzothiazoline)-6-sulfonic acid MCL1 apoptosis regulator, BCL2 family member Homo sapiens
