A high level of STEAP3 expression supports the proliferation of numerous cancer cells by stimulating iron uptake and preserving iron storage, including glioblastoma [17], hepatocellular carcinoma [18], bladder cancer [19], colorectal cancer [20], etc. Despite the significance of the STEAP gene family in tumorigenesis and development, comprehensive analyses of the importance of STEAP3 in OC remain insufficient. Here, STEAP3 is linked to urinary bladder carcinoma.
