Transcriptomic analysis of Zinc treatment in Acinetobacter baumannii

In A. baumannii, adequate zinc acquisition is required for the bacterium to express its full virulence potential. In excess, zinc can also induce significant cellular toxicity. The impact of zinc toxicity on biological systems has primarily been linked to its ability to bind non-zinc metalloproteins. The consequences of zinc intoxication include enhanced oxidative stress susceptibility and alteration of carbon source utilisation. Overall design: The association between zinc stress and oxidative stress has been studied in significant detail, where the oxidative stress catalyses the ability of zinc to bind non-cognate metalloproteins, and particular, iron-sulphur cluster proteins在鲍曼不动杆菌（A. baumannii）中，该菌需获取充足锌离子方可展现全部毒力潜能。而锌离子过量时，亦会引发显著的细胞毒性。锌毒性对生物系统的影响，主要与其结合非锌金属蛋白的能力相关。锌中毒的后果包括增强氧化应激易感性以及改变碳源利用模式。实验整体设计：研究团队已对锌胁迫与氧化应激之间的关联展开详尽探究，其中氧化应激可催化锌结合非同源金属蛋白的能力，尤其是铁硫簇蛋白。
