The forced miR-18a-3p expression and miR-4286 can repress BZRAP1 to enhance proliferation and movement of GC cells, thus leading to tumor progression in vitro (Liu et al., 2019; Tsai et al., 2020), whereas miR-320a suppresses the progression of GC by targeting PBX3 (Li et al., 2019). The gene discussed is TSPOAP1; the disease is gastric cancer.
