various cellular events such as transcription. Novel HDAC inhibitors were designed and synthesised to promote higher levels of recombinant protein production in tobacco cell cultures. The effect of these chemical enhancers on the epigenetic profiles in plant cells has been evaluated by molecular docking, in vitro and in vivo studies. The addition of these novel enhancers led to an increase in histone
组蛋白脱乙酰酶参与染色质重塑,因此在基因表达的表观遗传调控中发挥着至关重要的作用。 HDAC 抑制剂改变组蛋白和非组蛋白的乙酰化状态,以调节转录等各种细胞事件。设计和合成了新型 HDAC 抑制剂,以促进烟草细胞培养物中重组蛋白产量的更高水平。这些化学增强剂对植物细胞表观遗传谱的影响已通过分子对接、体外和体内研究进行了评估。这些新型增强子的添加导致组蛋白 H3 乙酰化水平增加,从而促进细胞培养物中重组蛋白积累水平的增加。这些结果可以为这些增强剂的应用铺平道路,以改善基于植物细胞的系统中高价值产品的生产。
