摘　　要：运用蛋白质组学相关技术对暴露于酸化海水中的中华哲水蚤全蛋白进行分析,结果表明,对照组、CCO20.08%和CCO20.20%处理组中华哲水蚤的双向电泳图谱上可以分别分辨出1 191、1 117和946个蛋白点,选取其中43个差异蛋白进行MALDI-TOF/TOF质谱鉴定,成功鉴定出23个差异蛋白,这些蛋白主要与蛋白合成和分解、能量代谢、DNA分子修复以及解毒过程有关。This study compared proteim profiles of Calanus sinicus cultured under CCO 2 0.08% and CCO2 0.20%CO2-acidified seawater for 4 days using a proteomic approach,and identified the differentially expressed proteins. The results are shown that,1 191,1 117 and 946 protein spots of C.sinicus in control,CCO 2 0.08% and CCO2 0.20%groups were detected in the two-dimensional electrophoresis gels,respectively.The 43 protein spots were selected based on their differential expression between control and CCO2 0.08% group,CCO2 0.20% group,and 23 proteins of which were identified by MALDI-TOF/TOF mass spectrometry.The data demonstrated that these differentially expressed proteins were associated with protein synthesize and proteolysis,energy metabolism,DNA repaired and detoxified of organisms.
