Prevalence of <i>bcl-2</i> Rearrangement in Patients with Hepatitis C Virus–Related Mixed Cryoglobulinemia with or without B-Cell Lymphomas

Abstract

Rearrangement of bcl-2 was found with increased frequency in patients with chronic HCV infection and mixed cryoglobulinemia. The frequency was greatest in patients with type II mixed cryoglobulinemia. The high ratio of Bcl-2 to Bax in patients with bcl-2 rearrangement and disappearance of the rearrangement with antiviral therapy suggest that the translocation is associated with the antiapoptotic function of Bcl-2 and that HCV infection is linked to inhibition of B-cell apoptosis.
