Disruption of B-myb in DT40 cells reveals novel function for B-Myb in the response to DNA-damage

Oncogene volume 24, pages 7127–7134 (2005)Cite this article

Abstract

B-Myb is a highly conserved vertebrate member of the Myb transcription factor family, which is expressed in virtually all proliferating cells. A large body of evidence suggests that B-Myb plays an important role in cell cycle regulation; however, the exact nature of its function has not yet been clarified. We have used gene targeting in chicken DT40 cells, a cell line exhibiting very high rates of homologous recombination, to create cells expressing endogenous B-myb in a doxycyclin-dependent manner. We find that the cells proliferate well in the absence of B-Myb, suggesting that B-Myb is not essential for cell proliferation per se. However, cells lacking B-Myb are more sensitive to DNA-damage induced by UV-irradiation and alkylation. Our work provides the first direct evidence for a novel function of B-Myb in the response to DNA-damage. The cells described here should be a useful model to characterize this function in more detail.
