Our previous study reported that tRF-5026a could inhibit the proliferation, cell cycle progression, and migration of gastric cancer cells by regulating the phosphatase and tensin homologue deleted on chromosome ten/phosphatidylinositol 3-kinase/protein kinase (PTEN/PI3K/AKT) signaling pathway [25]. The gene discussed is WEE1; the disease is gastric cancer.
