Figure Lengend Snippet: Increased expression of URG4 in osteosarcoma tissues and cell lines. a URG4 expression was significantly increased in osteosarcoma tissues than corresponding normal tissues by HE and IHC, respectively (× 200 magnification). b PCR determined URG4 mRNA expression in osteosarcoma cell lines (HOS, MG63, Saos-2, U2OS, and 143B), and hFOB 1.19 was used as control. c Western blot assay determined URG4 protein expression in osteosarcoma cell lines (HOS, MG63, Saos-2, U2OS, and 143B), and hFOB 1.19 was used as control. d The mRNA expression level of the URG4 in HOS and MG63 cell lines following transfection as determined by RT-qPCR. e The protein expression level of URG4 in HOS and MG63 cell lines following transfection as determined by western blot assay. HE: hematoxylin and eosin; IHC: Immunohistochemistry; URG4: upregulated gene 4; Normal: normal tissues; OS: osteosarcoma tissues; K: blank group; NC: negative control. * p < 0.05, ** p < 0.01 vs the NC
Article Snippet: Five osteosarcoma cell lines (MNNG/HOS, 143B, U2OS, Saos-2, and MG63) and a human osteoblast cell line (hFOB 1.19) were purchased from Shanghai Genechem Company Ltd. U2OS, 143B, and MG63 cells were cultured in DMEM (Gibco, USA), whereas MNNG/HOS and Saos-2 cells were cultured in RPMI 1640 medium. hFOB 1.19 cells were cultured in 1:1 DMEM/Ham’s F12 medium supplemented with 2.5 mM l -glutamine and 0.3 mg/ml G418 (Sigma-Aldrich, St Louis, MO, USA).
