Problems solved by technology

At present, although the diagnosis and treatment methods of glioma are in the stage of continuous improvement, the survival rate of glioma patients has not been significantly improved.
The diagnosis of glioma is still in the empirical stage based on clinical, pathological and imaging information, and once diagnosed, most of them are in the middle and advanced stages, and the survival rate after surgery is not optimistic

Abstract

The invention belongs to the biotechnical field, and discloses a glioma prognostic marker circ15:101235082|101235577 and applications, namely a reagent for detecting circRNA circ15:101235082|101235577coming from brain tissues; and the glioma prognostic marker is used for preparing a prognostic preparation for patients with glioma. Study proves that patients with glioma having higher expression quantity of circRNA circ15:101235082|101235577 have higher postoperative survival rate. The prognostic prediction on the patients with glioma can be made by detecting the expression level of circRNA circ15:101235082|101235577 in glioma tissues of patients with glioma.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a serum circRNA marker for glioma prognosis, the application of a reagent for detecting the marker for preparing a glioma prognosis preparation, and a kit. Background technique [0002] Glioma is the most frequent brain tumor in adults, accounting for 40.49% of intracranial tumors. From the time of diagnosis, the average life expectancy of patients with glioma is less than five years. In order to diagnose and treat glioma, a malignant disease highly correlated with genetic material, it is necessary to explore its pathogenesis at the level of molecular biology and from the expression of genetic information. At present, although the diagnosis and treatment methods of glioma are in the stage of continuous improvement, the survival rate of glioma patients has not improved significantly. The diagnosis of glioma is still in the empirical stage based on clinical, pathological and imaging in...
