Ribonucleotide reductase represents a novel therapeutic target in primary effusion lymphoma.

ABSTRACT: Primary effusion lymphoma (PEL) is a highly aggressive B-cell malignancy that is closely associated with one of oncogenic viruses infection, Kaposi's sarcoma-associated herpesvirus. PEL prognosis is poor and patients barely survive >6 months even following active chemotherapy interventions. There is therefore an urgent need to discover more effective targets for PEL management. We recently found that the ribonucleotide reductase (RR) subunit M2 is potentially regulated by the key oncogenic hepatocyte growth factor/c-MET pathway in PEL. In this study, we set to investigate the role of RR in PEL pathogenesis and to evaluate its potential as a therapeutic target. We report that the RR inhibitor 3-AP actively induces PEL cell cycle arrest through inhibiting the activity of the nuclear factor-κ
