Imatinib Mesylate 42-50 BCL2 like 1 Homo sapiens 117-122 28319085-4 2017 These included the BCL2L1 and MCL1 combination, which was also effective in imatinib-resistant cells. Imatinib Mesylate 76-84 BCL2 like 1 Homo sapiens 19-25 26987906-5 2016 Disrupting this antiapoptotic phenotype by inhibition of BCL-XL via RNA interference or A-1331852, a novel, potent and BCL-XL-selective inhibitor, resulted in extensive apoptosis either alone or in combination with imatinib, dasatinib or nilotinib, both in cell lines and in primary CD34(+) cells from patients with high levels of CIP2A. Imatinib Mesylate 215-223 BCL2 like 1 Homo sapiens 57-63 24504921-8 2014 Mechanistically, depletion of the transcription factor GATA4 resulting in decreased levels of its prosurvival targets Bcl-2 and Bcl-XL was an underlying cause of imatinib toxicity. Imatinib Mesylate 162-170 BCL2 like 1 Homo sapiens 128-134 24088895-9 2014 Sequential treatment with activin A and imatinib decreased Bcr-Abl, procaspase-3, Mcl-1, and Bcl-xL and also induced cleavage of procaspase-3/poly(ADP-ribose)polymerase. Imatinib Mesylate 40-48 BCL2 like 1 Homo sapiens 93-99 23613979-8 2013 Sequential treatment with ACM and imatinib induced Bcr-Abl down-regulation, cytochrome c release into the cytosol, and caspase-3 activation, as well as decreased Mcl-1 and Bcl-xL expressions, but did not affect Fas ligand/Fas death receptor and procaspase-8 expressions. Imatinib Mesylate 34-42 BCL2 like 1 Homo sapiens 172-178 26473951-6 2015 In KOSR-protected CML cells, imatinib still inhibited the BCR-ABL tyrosine kinase, reduced the phosphorylation of STAT, ERK and AKT, down-regulated BCL2, BCLxL, MCL1 and up-regulated BIM. Imatinib Mesylate 29-37 BCL2 like 1 Homo sapiens 154-159 21115411-10 2011 CONCLUSION: We provide the first preclinical evidence that Bcl-2/Bcl-x(L) inhibition with ABT-737 synergistically enhances imatinib-induced cytotoxicity via apoptosis, and that direct engagement of apoptotic cell death may be an effective approach to circumvent imatinib-resistance in GIST. Imatinib Mesylate 123-131 BCL2 like 1 Homo sapiens 65-70 21115411-10 2011 CONCLUSION: We provide the first preclinical evidence that Bcl-2/Bcl-x(L) inhibition with ABT-737 synergistically enhances imatinib-induced cytotoxicity via apoptosis, and that direct engagement of apoptotic cell death may be an effective approach to circumvent imatinib-resistance in GIST. Imatinib Mesylate 262-270 BCL2 like 1 Homo sapiens 65-70 17926190-7 2007 Enhanced apoptosis, cytochrome C release, and caspase 3 cleavage as well as noticeable decrease of Mcl-1 and Bcl-XL were observed in K562 cells treated with both (-)gossypol and imatinib. Imatinib Mesylate 178-186 BCL2 like 1 Homo sapiens 109-115 20094798-5 2010 Nutlin-3 and imatinib synergistically induced Bax activation, mitochondrial membrane depolarization, and caspase-3 cleavage leading to caspase-dependent apoptosis, which was inhibited by overexpression of Bcl-XL. Imatinib Mesylate 13-21 BCL2 like 1 Homo sapiens 205-211 19934315-12 2009 We conclude that imatinib sensitizes Bcr-Abl(+) cells to cisplatin by simultaneous inhibition of p53 transactivation, induction of p53 accumulation predominantly in the cytoplasm, and reduction of Bcl-x(L). Imatinib Mesylate 17-25 BCL2 like 1 Homo sapiens 197-205 20723293-0 2010 [Effects of STI571 combined with As2O3 on proliferation, apoptosis and caspase 3, Bcl-xL expression of K562 cells]. Imatinib Mesylate 12-18 BCL2 like 1 Homo sapiens 82-88 20723293-8 2010 The STI571 combined with As2O3 can enhance these two effects, increase the expression of caspase-3 mRNA and decrease the expression of bcl-xL mRNA. Imatinib Mesylate 4-10 BCL2 like 1 Homo sapiens 135-141 20723293-9 2010 Therefore, the effect of STI571 combined with As2O3 on expression of caspase 3 and bcl-xL mRNA may be one of molecular mechanisms underlying their synergic antileukemia efficacy. Imatinib Mesylate 25-31 BCL2 like 1 Homo sapiens 83-89 18088462-0 2007 [STI571 induces apoptosis of K562 cells through down-regulation of anti-apoptotic protein Mcl-1 and Bcl-xl expression]. Imatinib Mesylate 1-7 BCL2 like 1 Homo sapiens 100-106 18088462-8 2007 It is concluded that STI571 induces the apoptosis of CML cells by down-regulating the expressions of Mcl-1 and Bcl-xl, which suggests that Mcl-1 and Bcl-xl may play an important role in anti-apoptotic process of CML cells. Imatinib Mesylate 21-27 BCL2 like 1 Homo sapiens 111-117 18088462-8 2007 It is concluded that STI571 induces the apoptosis of CML cells by down-regulating the expressions of Mcl-1 and Bcl-xl, which suggests that Mcl-1 and Bcl-xl may play an important role in anti-apoptotic process of CML cells. Imatinib Mesylate 21-27 BCL2 like 1 Homo sapiens 149-155 17545631-5 2007 By treating CML cells with imatinib, we could show that the resulting inhibition of BCR-ABL leads to a decreased expression of tumor antigens, including survivin, adipophilin, hTERT, WT-1, Bcl-x(L), and Bcl-2 in correlation to a decreased development of CML-specific CTLs. Imatinib Mesylate 27-35 BCL2 like 1 Homo sapiens 189-194 17420275-9 2007 Furthermore, we show that the inhibition of Bcr-Abl kinase by treatment with imatinib caused the up-regulation of Gfi-1B in K562 cells, where Gfi-1B also cooperated with GATA-1 to repress Bcl-x(L) transcription. Imatinib Mesylate 77-85 BCL2 like 1 Homo sapiens 188-193 15039284-4 2004 In imatinib mesylate-resistant K562 cells displaying increased Bcr/Abl expression, bortezomib/flavopiridol treatment markedly increased apoptosis in association with down-regulation of Bcr/Abl and BclxL, and diminished phosphorylation of Lyn, Hck, CrkL, and Akt. Imatinib Mesylate 3-20 BCL2 like 1 Homo sapiens 197-202 11782377-7 2002 Synergistic potentiation of STI571-mediated lethality by PD184352 was associated with multiple perturbations in signaling and apoptotic regulatory pathways, including caspase-dependent down-regulation of Bcr-Abl and Bcl-2; caspase-independent down-regulation of Bcl-x(L) and Mcl-1; activation of JNK, p38 MAPK, and p34(cdc2); and diminished phosphorylation of Stat5 and CREB. Imatinib Mesylate 28-34 BCL2 like 1 Homo sapiens 262-270 12231544-5 2002 STI571/flavopiridol-mediated apoptosis was associated with the caspase-independent down-regulation of Bcl-x(L) and Mcl-1, activation of extracellular signal-regulated kinase and c-Jun NH(2)-terminal kinase, and the caspase-dependent release of Smac/DIABLO and loss of deltapsi(m). Imatinib Mesylate 0-6 BCL2 like 1 Homo sapiens 102-110 11313280-6 2001 STI-571-mediated apoptosis correlated with the inhibition of Stat-5 and MAP kinase activation and a reduction in overexpressed bcl-x(L) but not in PTP1B. Imatinib Mesylate 0-7 BCL2 like 1 Homo sapiens 127-135 10815921-0 2000 The tyrosine kinase inhibitor CGP 57148 (ST1 571) induces apoptosis in BCR-ABL-positive cells by down-regulating BCL-X. Imatinib Mesylate 30-39 BCL2 like 1 Homo sapiens 113-118 11368438-4 2001 Combined treatment with As2O3 and STI-571 also resulted in greater reductions in the levels of Bcl-x(L), XIAP and Akt, and inhibition of Akt kinase activity. Imatinib Mesylate 34-41 BCL2 like 1 Homo sapiens 95-103 11179439-6 2001 Use of the Bcr-Abl tyrosine kinase inhibitor STI-571 resulted in a reduction in Bcl-xL levels and potentiation of dexrazoxane-induced apoptosis related to an earlier onset and more extensive cleavage of caspase-3.
