摘要: Background Identification of the proteins that are associated with estrogen receptor (ER) status is a first step in selecting drugs against hormone-dependent breast cancer. Recently, ER were reported using liquid chromatography and tandem mass spectrometry, microRNA (miRNA) profiling cancer subtype was demonstrated real-time-PCR. Methods We present herein two cases differential protein expression miRNA ER-positive -negative Results Proteins fatty acid metabolism uniquely detected The level miR-181a higher than ER-negative cancer, while miR-27a, miR-107, miR-195 lower compared Conclusion These suggest synthase (FAS) FAS-related miRNAs important
