Abstract:
Objective To investigate the expression of glycoprotein M6A(GPM6A)in glioma specimens and its prognostic signifi-cance.Methods Bioinformatics methods were used to analyze the expression of GPM6A in 325 cases obtained from the Chinese Glioma Genome Atlas(CGGA)database.The STRING online database was used to screen and analyze the possible protein PPI interaction net-work and GO functional annotation that interact with GPM6A to explore its potential mechanism.The relationships between GPM6A and glioma cell purity and the level of CD8+T cell were assessed using the TIMER2.0database.Results The online analysis of the CGGA database showed that GPM6A was expressed in histopathological grades(WHO:G2,G3,G4)and histopathological types,and there were significant differences in GPM6A expression levels between all grades and all types of gliomas(Grades:F=50.25,P＜0.001;Types:F=14.26,P＜0.001);the expression level of GPM6A was closely related to molecular IDH mutation status,combined deletion of 1p19q,and patient age(all P＜0.01),regardless of patient gender(t=1.45,P＞0.05).The expression level of GPM6A in primary glioma was higher than that in secondary glioma,and the difference was not statistically significant(t=1.82,P＞0.05).The survival time of patients with low GPM6A expression was significantly shortened(x2=69.79,P＜0.001),but in glioblastoma(GBM)patients,regard-less of the level of GPM6A expression,there was no difference in survival time(x2=0.63,P＞0.05).GO functional analysis showed that GPM6A was closely related to the functions of transmembrane protein transport,synapse formation and development,and information ex-change between cells in the nervous system.TIMER2.0database analysis showed that GPM6A was positively correlated with glioma tumor cell purity and the level of CD8+T cell.Conclusion The prognosis of glioma patients with low GPM6A expression is significantly worse than that of patients with high expression,and its expression level can be used as a predictor for evaluating the prognosis of glioma.
