LINC00852 and osteosarcoma: LINC00852 is the most differentially expressed lncRNA in receptor tyrosine kinase AXL-related exosomes, which can partially up-regulate the AXL expression by competitively binding with miR-7-5p, and AXL-related exosomes LINC00852 up-regulate the proliferation, migration and invasion of osteosarcoma cells [7].
