The results calculated according to the ESTIMATE algorithm showed that P4HA3 in different tumor types such as BLCA, BRCA, COAD, ESCA, GBM, KICH, KIPAN, KIRP, LGG, LIHC, LUSC, OV, PAAD, PCPG, PRAD, READ, STAD, and UVM was associated with significant positive correlations between the three scores of ESTIMATEScore, ImmuneScore, and StromalScore (Figure 7D). The gene discussed is P4HA3; the disease is neoplasm.
