微囊藻受短时超声波胁迫蛋白表达差异研究(英文)

为探索微囊藻抵抗短时超声波表达调控相关蛋白质,应用双向电泳技术对微囊藻短时超声波处理蛋白质表达进行分析,结果表明,71个蛋白质点上调,56个蛋白质点下调,54个新增蛋白质点,21个消失蛋白质点。对其中8个差异大的蛋白质点采用MALDA-TOFMS进行质谱分析,并经数据库搜索匹配,鉴定出2个未知蛋白、6个功能蛋白。这些功能蛋白参与抗氧化和抗炎症、磷酸盐合成、电子传递等生理过程,实现微囊藻在短时超声波胁迫下的代谢平衡和自我保护。

Differentially Expressed Proteome of Microcystis under Short-time Ultrasonic Stress

This study was conducted to explore the regulation mechanism for key protein expression. The Microcystis treated by short-time ultrasonic wave was select-ed to analyze the total protein based on 2-DE. The results showed that there were 71 up-regulated protein spots, 56 down-regulated protein spots, 54 new protein spots and 21 protein spots disappeared under short-time ultrasonic stress. Eight dif-ferential proteins were chosen for further MALDI-TOFTOF/MS analysis, and the re-sults showed that 2 unknown proteins and 6 functional proteins were detected. These proteins were relevant to some physiological processes, such as antioxidation and anti-inflammatory process, phosphate synthesis and electron transfer, which is beneficial to the metabolic balance and self-protection under short-time ultrasonic stress.
