【摘要】利用我室建立的原位鼻咽癌裸鼠模型,建立了稳定性较好的鼻咽癌裸鼠血清蛋白质2-DE方法,并比较了原位鼻咽癌裸鼠血清与对照组裸鼠血清蛋白质2-DE图谱之间的差异.与正常裸鼠血清比较,原位鼻咽癌裸鼠模型组血清增加了4个蛋白质点.利用MALDI-TOF质谱技术对血清差异蛋白点进行鉴定,发现SAA-1前体(serumamyloidA-1 protein precursor)在鼻咽癌裸鼠模型组血清中明显高表达,为寻找鼻咽癌血清生物标志物提供了有利的线索.更多还原

【Abstract】 On the basis of in situ nasopharyngeal carcinoma(NPC)nude mouse model previously founded in our lab,stable 2-DE method for serum proteomic analysis of NPC nude mouse was established,and the 2DE profile of serum proteome of in situ NPC nude mouse was compared with that of control nude mouse.Compared to control nude mouse group,in situ NPC nude mouse group exhibited four more protein spots.By using MALDI-TOF mass spectrum technology,it was found that SAA-1 precursor was significantly overexpressed in the serum of in situ NPC nude mouse group.The results may provide a beneficial clue for exploring potential serum biomarks of NPC.更多还原
