摘要: 目的:分析3种不同HPV型别的宫颈癌细胞株Siha、Caski和C33的分泌蛋白表达及种类,寻找其共性分泌蛋白标志物,为临床早期发现及针对性干预提供依据。方法:采用3种不同宫颈癌SiHa、Caski和C33细胞株的分泌蛋白,运用LC-MS/MS和Maxquant的非标记技术,筛选出宫颈癌分泌蛋白的种类及分类。结果:共鉴定肽段数21 609个,蛋白数2 895个。其中3种宫颈癌细胞株共性蛋白共729种,占29.2%;特异性蛋白Siha细胞株含128种,Caski细胞株含143种,C33细胞株含859种。对于结果中729种共性蛋白进行分析,有以下4类较为集中的类型:热休克蛋白类(HSPs)共14种;异质性核糖核蛋白类(HNRP)共8种;层黏连蛋白类(LN)共4种;阿尔多酮还原酶1类(AKR1)共2种。其中,溶酶体信号通路所占比例最大(39种)。结论:SiHa、Caski和C33细胞株的分泌蛋白中共有729种共性蛋白,其中4类集中的蛋白类型均先后在研究中证实对宫颈癌的进程和发展有影响,并且可能与溶酶体信号通路有关。可为筛选高危型HPV感染的宫颈癌患者的血清标志物提供依据。

Abstract: OBJECTIVE:To analyze secretory proteins from three different kinds of cervical cancer cell lines (Siha, Caski and C33) and to identify specific proteins as biomarkers for earlier detection and for treatment. METHODS:Label-free quantitative proteomics technology processes were performed successively:protein cleavage, protein quantification and proteolysis. Then,the secretory proteins were analyzed and were picked out by LC-MS/MS and unlabeled Maxquant analyses. RESULTS:21 609 kinds of peptides and 2 895 different kinds of proteins were found. Meanwhile,collective proteins made up 29.2% of total with 729 different types. The numbers of proteins for Siha,Caski and C33 were 128,143 and 859,respectively. Among the collective proteins,there were 4 main protein species:heat shock proteins (HSPs)(14 proteins), heterogeneous nuclear ribonucleoprotein (HNRP)(8 proteins), laminin (LN)(4 proteins) and Aldo-keto reductase family 1(AKR1) (2 proteins). In addition,the lysosomal signaling pathway accounted for the largest proportion (39 proteins). CONCLUSION:There were 729 kinds of collective proteins among the three cervical cancer cell lines which belonged to the HPV16 type. Among the collective proteins,4 main protein species were concluded which have already been confirmed to play a significant role in the cervical cancer process. They may also belong to the lysosomal signaling pathway,The results may provide certain research directions for tumor molecular markers in the future.
