Abstract

The putative tumor suppressor gene WW domain containing oxidoreductase (WWOX) spans a common fragile site (CFS) on chromosome 16q23.3. CFSs are regions of profound genomic instability and sites for genomic deletions in cancer cells. Therefore, WWOX is structurally altered in diverse nonhematological cancer types. However, the function of WWOX in hematological tumor types, including multiple myeloma (MM) and monoclonal gammopathy of undetermined significance (MGUS) remains unclear. WWOX expression and methylation in patients with MM, MGUS, or noninvasive lymphoma (control) were analyzed using reverse transcription‑ and methylation specific‑polymerase chain reaction analysis. Variant WWOX transcripts were detected in 65 and 50% of patients with MM and MGUS, respectively, compared with 10% of controls. WWOX expression was higher in patients with MM, and WWOX promoter methylation was detected in 35% of patients with MM compared with 5% of patients with MGUS and 4% of controls. WWOX promoter methylation was significantly associated with shorter overall survival time of patients, in particular those with MM who were never treated with novel agents. Genomic alterations, including deletions and promoter methylation that affect WWOX expression occur early and may be involved in the pathogenesis, progression, and prognosis of MM.
