We have previously shown vitamin D receptor (VDR) expression in plasmablastic ABC-DLBCL cells and demonstrated inhibition of their growth by exogenous vitamin D (VitD3); however, the vitamin D biology of GC-DLBCL cells remained unclear.<h4>Design/methods</h4>Study of VDR and related molecule expression and vitamin D response across a panel of DLBCL and myeloma cell lines by western blot, qPCR, flow cytometry and cell counting techniques. Here, VDR is linked to aneurysmal bone cyst.
