We demonstrated that metallopanstimulin-1 (MPS-1, RPS27) inhibited growth of tumors formed by head and neck squamous cell carcinoma cells and reduced paxillin gene expression. The present study examined whether and how MPS-1 affects another type of cancer, multiple myeloma (CAG). Enhanced expression of MPS-1 dramatically inhibited CAG in vitro and in vivo. Overexpression of MPS-1 resulted in decreased fibroblast growth factor (FGF) receptor 3 and impaired endogenous MAPK/ErK signaling. MAPK/ErK signaling was not stimulated by adding recombinant FGF2 to myeloma cells overexpressing MPS-1. These data suggest that MPS-1 suppresses CAG growth and that weakened FGF signaling may contribute to this effect.
