1 Key role for Bak activation and Bak-Bax interaction in the apoptotic response to vinblastine. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
2 Key role for Bak activation and Bak-Bax interaction in the apoptotic response to vinblastine. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
3 In this study, we investigated the role of Bak in vinblastine-induced apoptosis. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
4 Bak was mainly monomeric in untreated KB-3 cells, and multimers corresponding to dimer, trimer, and higher oligomers were observed after vinblastine treatment. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
5 Immunoprecipitation with a conformation-dependent Bak antibody revealed that vinblastine induced Bak activation. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
6 Immunoprecipitation with a conformation-dependent Bak antibody revealed that vinblastine induced Bak activation. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
7 Reciprocal immunoprecipitations indicated that vinblastine induced the interaction of active Bak with active Bax. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
8 These results highlight Bak as a key mediator of vinblastine-induced apoptosis and show for the first time activation and oligomerization of Bak by an antimitotic agent. Vinblastine BCL2 antagonist/killer 1 Homo sapiens
