When it comes to ALDH1A3, as shown in Figure 3, the mRNA transcription level of ALDH1A3 was significantly higher in prostate cancer tissues than that in normal tissues in both TCGA datasets and GEO datasets (p = 1.63 × 10−12 and p = 4.33 × 10−2, respectively). The gene discussed is ALDH1A3; the disease is prostate carcinoma.
