The aim of this study was to use two-dimensional electrophoresis (2-DE) coupled with multivariate principal component analysis (PCA) to characterize the quantitative changes in the protein composition of the CEM T-lymphoblastic leukemia cell line after treatment with bohemine (BOH), a synthetic olomoucin-derived cyclin-dependent kinase inhibitor (CDKI). Cell classification, reflecting protein patterns, clearly distinguished two main groups: one group consists of 9, 12 and 24 h treated BOH cells while the second is represented by the 0 and 24 h control untreated cells and the 6 h BOH-exposed CEM lymphoblasts. Discriminant protein spots differentially expressed in the BOH-treated CEM cells were selected for identification by matrix assisted laser desorption/ionization-mass spectrometry (MALDI-MS) or electrospray ionization-tandem MS (ESI-MS/MS). Five of the selected protein spots were unequivocally identified as alpha-enolase, triosephosphate isomerase, eukaryotic initiation factor 5A, and alpha- and beta-subunits of Rho GDP-dissociation inhibitor 1. These proteins, all significantly downregulated in CEM T-lymphoblast leukemia in the course of BOH treatment, are known to play an important role in cellular functions such as glycolysis, protein biosynthesis, and cytoskeleton rearrangement. These results indicate that the cellular effects of olomoucine-derived CDKIs are not dependent on their ability to inhibit CDKs and could be mediated by several factors such as a decrease in protein synthesis and/or glycolysis which in turn diminishes the ability of cancer cells to function.
