For the cell migration or chemotaxis assay, cultured MM cells (5 105 cells per insert) were washed and suspended in RPMI 1640 medium containing 0.5% BSA. Furthermore, CXCL16 increased cell-cell adhesion and induced cellular proliferation in an NF-B-dependent manner. Moreover, oncogenes with tyrosine kinase activity, such as BCR/ABL, Flt3-ITD, and c-Kit, alter the redox homeostasis in leukemic cells contributing to proliferative and anti-apoptotic effects [27]. Cell adhesion-mediated drug resistance (CAM-DR) is associated with activation of NF-B (RelB/p50) in myeloma cells. Add 50 L of Calcein Ultragreen AM stock solution into 10 mL of Adhesion Assay Buffer and mix well.

Add 100 L volumes of cells on a plate coated with desired coating material. The proteasome inhibitors bortezomib and carfilzomib, which are widely used in the clinic, induce apoptosis by increasing intracellular ROS levels and generating an oxidative stress [38, 39]. Cyclin D1 triggered the phosphorylation of ERK1/2 (Figure (Figure5B)5B) and S6K (Supplementary Figure 5B) after the addition of the fusion protein in the culture medium, consistent with our observations in cyclin D1-expressing MM cells.

This is considered to be a side effect of the endoplasmic reticulum (ER) stress generated by the accumulation of unfolded proteins and the stimulation of the unfolded protein response (UPR) pathway. The cells were incubated for 4 h at 37C, and the number of migrating cells within the bottom of the insert was counted by flow cytometry. The proteins were blotted and analyzed using the indicated Abs. The relationship between the types of soluble and/or physical factors and the molecular groups of MM are largely unknown, except for a high level of 7 integrin associated with the molecular group of MM patients expressing the MAF transcription factor [32]. Myeloma cell death can be achieved through the generation of ROS that follows ER stress and UPR activation [46].

We report here the characterization of new biological functions of cyclin D1 in myeloma cells. Only CD10-negative cells corresponding to myeloma cells were analyzed. NOX2 produces ROS in B cells and participates into lymphoma and leukemia cells death [42, 43]. D1-GFP-expressing cells had the same oxygen consumption rate (OCR) as GFP-expressing cells (Supplementary Figure 3). D1-GFP-expressing cells were more sensitive to bortezomib than GFP-expressing to chronic treatment with bortezomib but not carfilzomib (Supplementary Figure 2A). The slides were then stained with a rhodamine-stained phalloidin probe (Molecular Probes) for selectively visualizing F-actin, and DAPI (4,6-diamidino-2-phenylindole dihydrochloride, Molecular Probes) for nuclear counterstaining.

Thus, it has been proposed that dysregulation of one CCND gene encoding cyclin D is a unifying event of MM pathogenesis [2].
