lncRNA DARS-AS1 promotes the progression of osteosarcoma by regulating miR-532-3p/CCR7 [36]; lncRNA BACE1-AS regulates the proliferation, migration, and invasion of osteosarcoma cells through the miR-762/SOX7 axis [37]; lncRNA SNHG1 promotes osteosarcoma progression by upregulating S100A6 through miR-493-5p [38]. The gene discussed is CCR7; the disease is osteosarcoma.
