Jin et al. [111] demonstrated that linc-ROR knockdown downregulated the high mobility group AT-hook 2 (HMGA2) gene and upregulated miR-519d-3p to restrain migration, invasion, and EMT in gastric cancer, establishing a correlation with the miR-519d-3p/HMGA2 network. The gene discussed is LINC-ROR; the disease is gastric cancer.
