Our models identified probes whose respective genes are involved in pathways highly related to multiple myeloma, such as the PI3K-Akt, MAPK, JAK-STAT, and Wnt signaling pathways, the RAF/MAP kinase cascade, NF-kB-related pathways, and signaling by RAS and BRAF mutants. This evidence concerns the gene SOAT1 and plasma cell myeloma.
