激光捕获显微切割技术纯化的乳腺癌上皮细胞和间质比较蛋白质组学研究
Comparative proteome research of epithelial cells and stroma from invasive ductal carcionma patients
摘要
Abstract
Aim To study the difference of proteins expression of epithelial cells and stroma of breast canc-er patients.Methods Formalin-fixed paraffin-embed-ded tissue samples from invasive ductal carcionma pa-tients were stained by improved HE staining methods. And the neoplastic epithelium and stroma were micro-dissected using laser capture microdissection and ana-lysed by mass spectrometry.Results Total 43 1 differ-ent proteins were detected by mass spectrometry and there were respectively 384 and 298 different kinds of proteins identified in epithelial cells and stroma.A-mong them,25 1 proteins were commonly expressed in two samples,while the contents of 69 and 60 proteins in stroma were respectively higher or lower than the ones in epithelial cells.The expression level and local-ization of proteins identified in epithelial cells and stro-ma were associated with their roles in development and progression of tumor cells.Conclusions The differen-tial expression proteins between epithelial cells and stroma of invasive ductal carcionma patients may func-tion as biomarkers for breast cancer screenning,diag-nosis and prognosis.关键词
