ScholarBank@NUS Repository. https://doi.org/10.1016/j.febslet.2009.12.011 | Abstract: | DNA damage checkpoints are essential for maintenance of genome integrity. We report here that inducible overexpression of the transcription factor Sharp-1 results in an S and G2/M cell cycle arrest, concomitant with the upregulation of Brca1 and GADD45α expression. In addition, we show that endogenous Sharp-1 mRNA is increased by DNA-damaging agents. Consistently, Sharp-1 overexpressing cells exhibit reduced apoptosis in response to chemotherapeutic drugs along with lower p53 expression and activity. Our studies identify a novel function for Sharp-1 in cell cycle arrest and DNA damage-induced apoptosis. Inappropriate Sharp-1 expression may therefore be associated with tumorigenesis. © 2009 Federation of European Biochemical Societies. | Source Title: | FEBS Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/25145 | ISSN: | 00145793 | DOI: | 10.1016/j.febslet.2009.12.011 |
