Hub gene validation based on TCGA data in GEPIA. (A–D) Gene expression levels between tumours and normal tissues. (A) AGXT, (B) PTGER3, (C) SLC12A3, (D) ALOX5. (E–H) Survival analysis of the relevance between the overall survival time and the relative expression levels of the hub genes in KIRC. (E) AGXT, (F) PTGER3, (G) SLC12A3, (H) ALOX5. The red line represents the samples with high gene expression, and the blue line indicates the samples with low gene expression.
