Fig. 1: Expression of linc00645 in glioma and its prognostic significance in glioma patients.

a Heatmap were constructed using the differential lncRNA between glioma and normal tissues detected by significance analysis in TCGA database. b Expression of linc00645 in the TCGA cohorts. c Heatmap were constructed using the differential lncRNA between different grades of glioma and normal tissues detected by significance analysis in GEO dataset. d Expression of linc00645 in the GSE4290 cohorts. e Twenty-four significantly differential-expressed lncRNAs were detected among TCGA and GSE4290 datasets. f Volcano plot indicated that linc00645 were differential expressed in two group. g GO analysis were performed using the linc00645 positive-associated genes in TCGA datasets. h Kaplan–Meier survival analysis showed high level of linc00645 was correlated with poor overall survival time in TCGA data
