Alterations in the tear proteome of dry eye patients--a matter of the clinical phenotype.
PURPOSE. Previous studies demonstrated alterations in the tear proteome of dry eye patients. The aim of the present study was to analyze tear protein patterns of dry eye patients considering different clinical phenotypes in order to examine their influence on tear film protein composition. METHODS. We applied a surface-enhanced laser desorption/ ionization-time-of-flight (SELDI-TOF)/matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF)/TOF mass spectrometry (MS)‐based strategy to detect/identify candidate biomarkers. Tear samples of 169 patients, enrolled in two independent studies, were analyzed. Patients were subdivided into healthy controls (CTRL: N ¼ 39), aqueous-defici…
Serum proteome profiling of primary breast cancer indicates a specific biomarker profile.
Non-invasive biomarkers for early breast cancer detection are urgently needed, as the risk of recurrent morbidity and mortality is closely related to the stage of the disease at the time of primary surgery. Currently, there are no established clinical biomarkers for breast cancer. Evaluation of protein expression patterns in body fluids using proteomic technologies can be used to discover new biomarkers for the detection of breast cancer. The aim of this study was to identify a biomarker signature identifying primary non-metastatic breast cancer and healthy controls. We screened 91 serum samples including 45 breast cancer patients and 46 healthy women using a proteomic approach. We found 14…
