Bioinformatics Analysis of GFAP as a Potential Key Regulator in Different Immune Phenotypes of Prostate Cancer
Figure 5
Identification of a key node within the genetic and epigenetic regulatory networks. (a) The integration of DEG, lncRNA, miRNA, and methylation analyses to determine upregulated differentially expressed genes in groups and . (b) The four genes positively associated with prognosis were confirmed using a random forest blot in TCGA-PRAD cohort. (c) A Kaplan-Meier analysis of the 4-gene model using TGCA-PRAD cohort. (d) GFAP was identified as a key hub gene within the network using a protein-protein interaction analysis of the STRING Consortium database. (e) Spearman’s correlation analysis was performed to analyze correlations between GFAP transcription levels and immune-cell subsets for TCGA-PRAD cohort.
