CDH2 and osteosarcoma: To identify the potential downstream target genes related to lincFOXF1 in osteosarcoma, we conducted qRT‐PCR to assess expression of multiple molecules (such as N‐cadherin, Integrin, CD44, ICAM‐1, Vimentin, Fibronectin, GIT1 and FOXF1) in osteosarcoma cells after gain or loss of lincFOXF1 function.
