Abstract
Background: 3,4-Dihydro-6-[4-{3,4-dimethoxybenzoyl}-1-piperazinyl]-2(1H)-quinolinone (vesnarinone), a novel inotropic drug with unique and complex mechanisms of action, is known to show antitumor activity against several human malignancies. In the present study, vesnarinone-induced signal transduction of S-phase kinase-associated protein 2 (Skp2) and Nuclear Factor-kappa Beta (NF-κB) as molecular targets of oral malignant Burkitt’s lymphoma (Raji cells) was evaluated.
Materials and Methods: Raji cells were incubated with vesnarinone at concentrations of 0, 1.25x10-2, 2.50x10-2, or 5.0x10-2 Molar. After 24 h, chemotactic cell migration was examined by a Boyden chamber kit. Apoptosis induction was observed by caspase-9 colorimetric assay. To evaluate levels of Skp2, NF-kB, and α-tubulin, Western blot analysis was performed.
Results: Vesnarinone markedly suppressed chemotactic cell migration and significantly induced apoptosis by increasing the caspase-9 activity of Raji cells through down regulation of Skp2 and NF-κB.
Conclusion: Vesnarinone decreased the expression of Skp2 and NF-κB indicating these molecules may be targeted for the treatment of oral malignant Burkitt’s lymphoma (BL). The results of this work offer a promising therapeutic approach for BL tumors.
Keywords: Vesnarinone, chemotactic migration, apoptosis, Burkitt's lymphoma cell, Skp-2, NF-kB.
