Abstract

The invention relates to a marker associated with the diagnosis of malignant glioma, and belonges to the technical field of molecular biology, specifically, the marker is a TNC gene and the expression product of the TNC gene. The invention also provides application of the marker. The marker has the advantages of carrying out a comprehensive genomics and proteomics analysis of GBM, and by gene expression analysis and LC-MS / MS protein mass spectrometry analysis based on gene chips and RNA sequencing, finding that the TNC gene is up-regulated at the mRNA level and protein level. Survival analysis of TNC shows that the overexpression of TNC is related to the poor prognosis of GBM patients, indicating that TNC can be used as a GBM biomarker and a potential therapeutic target.

Description

technical field [0001] The invention relates to the technical field of molecular biology, in particular to a marker related to the diagnosis of malignant glioma and its application. Background technique [0002] The initial designation of GBM as glioblastoma multiforme was an attempt to describe the striking differences among different cells within the tumor, which also reflected molecular heterogeneity. Long before genomic technologies were able to define the molecular characteristics of GBM, a simple clinical phenomenon reshaped the concept of GBM as a single disease. Clinically, most glioblastomas (approximately 90%) are primary, and only a few progress from low-grade gliomas (secondary GBM). Primary and secondary GBMs show completely different molecular features, for example, epidermal growth factor receptor (EGFR) and phosphatase tensin homologue (PTEN) are often abnormal in primary GBMs, while TP53 is abnormal in secondary GBMs. Abnormal in episodic GBMS. Although s...
