Figure 5. Correlations between the expression levels of signature genes in GC and immune infiltration using TIMER. (A) AURKB, (B) BIRC5, (C) BUB1, (D) TPX2, (E) SST, and (F) GNG7. P < 0.05 was regarded as statistically significant. GC, gastric cancer; TIMER, Tumor Immune Estimation Resource; TPM, transcripts per million.
