SOX9 mRNA and protein expression in 30 osteosarcoma and corresponding noncancerous bone tissues were respectively detected by real-time quantitative RT-PCR assay and Western blot analysis. (A) Expression levels of SOX9 mRNA in osteosarcoma tissues and noncancerous bone tissues. ((B) A graphical representation of the SOX9 mRNA level expression profiles in A). (C) Expression levels of SOX9 protein in osteosarcoma tissues and noncancerous bone tissues. (D) A graphical representation of the SOX9 protein level expression profiles in (C). 'N' refers to noncancerous bone tissues; 'T' refers to osteosarcoma tissues.
