Nicotinamide (NAM) induced growth defects attributing the inhibition of Hst3 and Hst4 and consequent elevation of H3K56ac in yeast. Interestingly, H3K56 acetylation plays an important role in mammalian genomic stability, and the function of this modification in mouse embryos is not known. Hence, we designed to study the effects of NAM on H3K56ac and the possible functions of this modification related to mouse embryo development. We found that 20 mM NAM arrested mouse embryos at 2-cell stage, which possessed constitutive H3K56 acetylation and did not passed into M phase. Treatment using 20 mM NAM did not result in excessive reactive oxygen species( ROS) production and mitochondrial content, and aberrant mitochondrial distribution. Nuclear DNA fragmentation was not detectable in the arrested 2-cell but it was observed in blastocyst. Further we explored the possibility to overcome the NAM mediated arrest of 2-cell stage embryos, by I-CBP112 or resveratrol. Interestingly, I-CBP112 or resveratrol treated mouse embryos shows rescue effects caused by NAM. Finally, we demonstrated that Sirt1, a member of Sirtuins deacetylases family that target histone and non-histone proteins and maintain genome integrity, is involved in mitigating the NAM induced growth defects by promoting deacetylation of H3K56ac.
