Literature evidence In this study, we assessed the potential interactions in the combination of vincristine or vinblastine with gamma-radiation against human tumor cells in vitro.
IUPAC name methyl (1R,9R,10S,11R,12R,19R)-11-acetyloxy-12-ethyl-4-[(13S,15S,17S)-17-ethyl-17-hydroxy-13-methoxycarbonyl-1,11-diazatetracyclo[13.3.1.04,12.05,10]nonadeca-4(12),5,7,9-tetraen-13-yl]-8-formyl-10-hydroxy-5-methoxy-8,16-diazapentacyclo[10.6.1.01,9.02,7.016,19]nonadeca-2,4,6,13-tetraene-10-carboxylate

Gene or Protein evidence Treatment of BT-20 cells with vincristine, vinblastine, and/or vinorelbine resulted in upregulation of TP53 expression. On the other hand, treatment of SK-BR-3 cells with any of these vinca alkaloids led to an increase in the BAX/BCL2 mRNA ratio, implying the activation of the intrinsic apoptotic pathway. No concomitant alteration in TP53 expression was observed in treated SKBR- 3 cells. Regarding the miRNAs examined in this study, miR-222-3p expression exhibited the most remarkable modulations in both treated cell lines.
Target pathways NA
IC50 NA
Potency In addition, concomitant treatment of the MCF-7 cells with SKE and vincristine produced a potent anti-proliferative and pro-apoptotic effect compared to extract or drug alone.
Cell line/ mice model BT-20, SKBR- 3, MCF-7
Additional information  Vincristine binds irreversibly to microtubules and spindle proteins in S phase of the cell cycle and interferes with the formation of the mitotic spindle, thereby arresting tumor cells in metaphase. This agent also depolymerizes microtubules and may also interfere with amino acid, cyclic AMP, and glutathione metabolism, calmodulin-dependent Ca++ -transport ATPase activity, cellular respiration, and nucleic acid and lipid biosynthesis. This study suggests the possible involvement of miR-222-3p expression in breast cancer cell apoptosis, triggered by vincristine, vinblastine, and vinorelbine.
