Research Abstract

In this study, the mechanism underlying EBNA3C suppression of the INK4a/ARF expression was analyzed. We clarified that (1) EBNA3C does not influence the DNA methylation status of the INK4a/ARF promoters. (2) EBNA3C changes histone modifications of the p16 (INK4a) locus from active state to silent state. (3) EBNA3C association with RBP-Jkappa is essential for EBNA3C to function. These results suggest that EBNA3C regulates epigenetic histone modifications of the INK4a/ARF locus.
