Therapies for mantle cell lymphoma (MCL) are clinically unsatisfactory, and the search for effective drugs in vitro might foster the evaluation of their activity in vivo. We have investigated the effects of the polyphenolic compound resveratrol on the MCL cell line Jeko-1 using a combination of flow cytometry, Western blotting and two-dimensional electrophoresis to identify the molecules involved in the induction of apoptosis and cell growth regulation. We show that resveratrol induces apoptosis in Jeko-1 cells and modulates several key molecules, including cyclin D1 (CCND1), p53 (TP53), p21 (CDKN1A), BCL2, BAX, Bcl XL (BCL2L1), caspase 9 (CASP9) and p27 (CDKN1B). By high-resolution 2D-PAGE and nano-reverse phase-high performance liquid chromatography coupled with tandem mass spectrometry, we identified 32 differentially expressed proteins in response to resveratrol treatment that belong to important cell death related networks (including c-myc, NF-kappaB and the mitochondrial apoptotic pathway). These findings may improve the understanding of mechanisms mediating the pro-apoptotic effects of resveratrol on MCL cells, and form the basis for its potential use as a therapeutic agent.
