As an upregulated lncRNA in ovarian cancer cells, ADAMTS9-AS1 knockdown decreases the migration and proliferation of ovarian cancer cells, increases Fe2+, iron, and reactive oxygen species (ROS) levels, and decreases the expression levels of GPX4 and SLC7A11 via the ADAMTS9-AS1/miR-587/SLC7A11 (Cai et al., 2022[12]). The gene discussed is ADAMTS9; the disease is ovarian cancer.
