The exploration of miR-1305 targets using the database (miRDB, miRTaBase and TargetScan) for target genes of miRNAs, revealed well-known genes essential for myeloma cell growth and proliferation such as insulin-like growth factor type 1 (IGF-1) and mouse double minute 2 homolog (MDM2) 38, 39. Here, MDM2 is linked to plasma cell myeloma.
