Breast cancer is one of the most common types of invasive cancer in females worldwide. Despite major advances in early cancer detection and emerging therapeutic strategies, further improvement has to be achieved for precise diagnosis to reduce the chance of metastasis and relapses. Recent proteomic technologies have offered a promising opportunity for the identification of new breast cancer biomarkers. Matrix-assisted laser desorption/ionization, time-of-flight mass spectrometry (MALDI-TOF MS) and the derived surface-enhanced laser desorption/ionization mass spectrometry (SELDI-TOF MS) enable the development of high-throughput proteome analysis based on comprehensive reliable biomarkers. In this review, we examined proteomic technologies and their applications, and provided focus on the proteomics-based profiling analyses of tumor tissues/cells in order to identify and confirm novel biomarkers of breast cancer.
乳腺癌是全球女性中最常见的浸润性癌症类型之一。尽管在早期癌症检测和新兴治疗策略方面取得了重大进展,但仍需进一步改进以实现精确诊断,从而降低转移和复发的几率。最近的蛋白质组学技术为鉴定新的乳腺癌生物标志物提供了一个有前景的机会。基质辅助激光解吸/电离飞行时间质谱(MALDI-TOF MS)及其衍生的表面增强激光解吸/电离质谱(SELDI-TOF MS)能够基于全面可靠的生物标志物开展高通量蛋白质组分析。在本综述中,我们研究了蛋白质组学技术及其应用,并着重介绍了基于蛋白质组学的肿瘤组织/细胞分析,以识别和确认新的乳腺癌生物标志物。
