medicine | enzyme is involved in activation of prodrug PR-104A designed to exploit tumor hypoxia. AKR1C3 protein is detected by Western blot in 7 of 23 cell lines and correlates with oxic PR-104A metabolism. AKR1C3 is unable to sensitize cells to 10 other bioreductive prodrugs and is associated with single-agent PR-104 activity across a panel of 9 human tumor xenograft models. Overexpression in two AKR1C3-negative tumor xenograft models strongly enhances PR-104 antitumor activity. Marked upregulation of AKR1C3 is found in a subset including hepatocellular, bladder, renal, gastric, and non-small cell lung carcinoma | Homo sapiens |
