ABSTRACT
This work aims to analyZe and compare the potential biomarkers between cervical cancer ( CC ) patients and healthy controls (HC).The urine samples of 11 CC patients (age (45.65 ± 5.6) years) and 11 HC patients (age (45.9 ± 3.2) years) were collected.The metabolites of urine samples from CC and HC were analyZed by using ultra performance liquid chromatography coupled with quadrupole orbitrap tandem mass spectrometry ( UHPLC-Q-Orbitrap MS/MS ) , which could provide evidence for early diagnose and disease pathway.The LC-MS data of urines were analyZed by principal components analysis ( PCA) and orthogonal partial least squares discriminant analysis ( OPLS-DA) to identify the potential biomarkers.Urine samples of CC patients were successfully discirminated from those of healthy controls.A total of twelve significant metabolites were found and identified as potential biomarkers according to the established UHPLC-Q-Orbitrap MS and MS/MS method.Identification of biomarkers between CC and HC patients may play an important role in the study of mechanism of UC and its pathway.
