AKR1B10P1 and hepatocellular carcinoma: AKR1B10P1, an isoform pseudogene of oncogenic AKR1B10, is validated as a down-stream target degraded by tumor-suppressing miR-138, and there existed a positive feedback from AKR1B10P1, by which miR-138 interacts with AKR1B10P1 via a ceRNA approach in HCC [27].
