SLC39A14 and neoplasm: In addition, it was demonstrated that circ-001842 sponges miR-502-5p, which targets SLC39A14, and thus, RCC patients showed high levels of circ-001842 and SLC39A14. Furthermore, elevated expression levels of SLC39A14 resulted in tumor growth in vivo, and increased RCC cell proliferation, migration and invasion, as well as EMT in vitro (Zeng et al., 2020).
