MICRORNAS (MIRNA) AS BIOMARKERS FOR DETECTING DIFFERENT GRADES OF GLIOMAS AND PATHWAYS OF GLIOMA PROGRESSION

摘要

This invention relates to a method for detecting, (i) malignant astrocytoma from normal brain tissue (ii) glioblastoma and anaplastic astrocytoma (iii) primary glioblastoma and secondary glioblastoma (iv) progressive pathway and denovo pathway comprises determining the level of expression of miRNAs listed in table 2, 3, 4, 5, wherein a higher or lower level of expression of miRNAs in the test sample as compared to the control sample differentiates and kit for characterizing a) malignant astrocytoma from normal brain tissue cell comprising reagent capable of specifically detecting the level of expression of the genes of miRNAs and instructions for using said kit for characterizing malignant astrocyoma from normal brain tissue cells b) glioblastoma from anaplastic astrocytoma comprising reagent capable of specifically detecting the level of expression of the genes of miRNAs and instructions for using said kit for characterizing glioblastoma from anaplastic astrocyoma c) primary glioblastoma from secondary glioblastoma comprising reagent capable of specifically detecting the level of expression of the genes of miRNAs and instructions for using said kit for characterizing primary glioblastoma from secondary glioldastoma, d) progressive pathway from denovo pathway comprising reagent capable of specifically detecting the level of expression of the genes of miRNAs and instructions for using said kit for characterizing progressive pathway from denovo pathway.
