确定组蛋白乙酰化是如何调节的对于治疗与其失调相关的许多疾病至关重要,包括心脏病,神经系统疾病和癌症。我们以前曾报道过乙酰辅酶A水平改变p300组蛋白乙酰化在体外的位点特异性的方式。在这里,我们进一步研究如何改变乙酰辅酶A浓度改变组蛋白乙酰化模式,通过改变p300的特异性。有趣的是,这些变化不是乙酰化的简单全局变化,而是位点特异性变化,其中一些位点的乙酰化增加,而另一些位点的乙酰化减少。我们还展示了p300抑制剂C646如何在体外和细胞中改变p300组蛋白乙酰化模式。本研究提供了深入了解调节p300残基特异性的机制,改变p300依赖的组蛋白乙酰化的潜在手段,以及改变细胞中组蛋白乙酰化模式的调查。
Determining how histone acetylation is regulated is vital for treating the many diseases associated with its misregulation, including heart disease, neurological disorders, and cancer. We have previously reported that acetyl-CoA levels alter p300 histone acetylation in a site-specific manner in vitro. Here we further investigate how changing acetyl-CoA concentrations alter the histone acetylation pattern by altering p300 specificity. Interestingly, these changes are not a simple global change in acetylation, but rather site specific changes, whereby acetylation at some sites increase while others decrease. We also demonstrate how the p300 inhibitor C646 can pharmacologically alter p300 histone acetylation patterns in vitro and in cells. This study provides insight into the mechanisms regulating p300 residue specificity, a potential means for altering p300 dependent histone acetylation, and an investigation into altering histone acetylation patterns in cells.
