Abstract

Helicases are present in viruses, prokaryotes, and eukaryotes, and several of them have been linked to human diseases. Here we study the role of one putative DEAD-box RNA helicase, MrDb (DDX18), in tumor cells. We show that MrDb is a nucleolar protein ubiquitously expressed in tumor cells and that it is more abundantly expressed in proliferating cells. Inhibition of MrDb with dominant negative mutant or a shRNA reduces tumor cell proliferation without inducing a cell cycle arrest or apoptosis. These findings suggest that MrDb is important for cell proliferation and that its inhibition could prevent tumor cell proliferation.
