The results indicated that high expression of SLC39A1 in LIHC (p=0.0042), high expression of SLC39A4 in CESC (p=0.035) and PAAD (p=0.021), however low expression of SLC39A8 in KIRP (p=0.0025), were associated with lower overall survival rates. Here, SLC39A4 is linked to cervical squamous cell carcinoma.
