Searching for Specific Markers of Glioblastoma: Analysis of Glioblastoma Cell Proteoforms

Аннотация

Using the sectional analysis of two-dimensional electrophoretic gels with liquid chromatography-mass spectrometry, proteoform profiles for individual genes expressed in cancer (glioblastoma) and normal (FLEH) cells were obtained. Profiles of more than 5000 genes were analyzed. It turned out that many genes encoding potential biomarkers of glioblastoma are characterized by sets of proteoforms that are different in normal and cancer cells. These proteoforms could be sources of highly specific markers and targets for therapy.
