Abstract
Using a mouse model with the tumor suppressor TRAF3 deleted from B cells, we identified Sox5 as a gene strikingly up-regulated in B lymphomas. Sox5 proteins were not detected in normal or premalignant TRAF3(-/-) B cells even after treatment with B cell stimuli. The Sox5 expressed in TRAF3(-/-) B lymphomas represents a novel isoform of Sox5, and was localized in the nucleus of malignant B cells. Overexpression of Sox5 inhibited cell cycle progression, and up-regulated the protein levels of p27 and β-catenin in human multiple myeloma cells. Together, our findings indicate that Sox5 regulates the proliferation of malignant B cells.Entities:
