In addition, miR-107, miR-149-5p, and miR-924 were shown to regulate SLC1A5 in esophageal cancer, breast cancer, and non-small-cell lung cancer cells respectively; however, they were sponged by circular RNA to prevent downregulation of SLC1A5 (Chang et al., 2021; Wang J. et al., 2021; Liu et al., 2022) (Table 3). This evidence concerns the gene SLC1A5 and esophageal cancer.
