Abstract

The invention discloses a glioma prognostic marker circ1:246186743|246186942 and application. A reagent for detecting circRNA circ1:246186743|246186942 of a glioma source is used for preparing a prognostic preparation of a glioma patient. Research proves that the glioma patient with relatively high expression of circRNA circ1:246186743|246186942 has relatively poor postoperative survival rate. A prognosis of the glioma patient is made by detecting the expression level of circ1:246186743|246186942 in glioma tissue of the glioma patient.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a circRNA marker for glioma prognosis, the application of a reagent for detecting the marker to prepare a glioma prognosis preparation, and a kit. Background technique [0002] Glioma is the most common malignant tumor in the brain, the incidence of glioma in China accounts for 35% to 60% of intracranial tumors, and the 5-year survival rate is only 20% to 30%. One of the most serious tumors faced. Traditionally, surgery is still the most important method for the treatment of glioma, but because most of the glioma grows infiltrating, it is easy to relapse after simple surgery, and the curative effect is not satisfactory. Therefore, it is an urgent research task in the field of neuroscience to find glioma prognostic markers to analyze the prognosis of patients, so as to improve the postoperative survival period of glioma patients and choose a reasonable follow-up treatment accordingly. ...
