Jiang et al. (2022a) found that circ_ 0000190 targeted the tumor suppressor zinc and ring finger 3 (ZNRF3) by competitively binding to miR-382-5p, inhibited gastric cancer cell proliferation, migration and invasion, and stimulated ferroptosis to occur, ultimately leading to inhibition of gastric cancer progression. This evidence concerns the gene ZNRF3 and gastric cancer.
