Furthermore, analyses of two gene expression omnibus (GEO) databases, GSE5900 (p<0.0001; Figure 7G) and GSE6477 (p=0.0350; Figure 7H), demonstrated that ODC1 mRNA was significantly increased in MM patients compared with smoldering myeloma (SMM), monoclonal gammopathy of undetermined significance (MGUS), and normal plasma (NP). The gene discussed is ODC1; the disease is smoldering plasma cell myeloma.
