Figure Lengend Snippet: TNF suppressed SOX9, PCNA and TRAF2 expressions in human growth plate tissue specimens (n=6) obtained from 2 children or human chondrocytes. (A, B) Quantitative analysis of SOX9 staining (yellow arrows), calculated as number of positive cells per mm². (C) Relative expression of SOX9 assessed by qPCR in HCS-2/8 cells treated for 72 hours with TNF at 10, 30, 100, 300 ng/ml concentrations (n=3). (D, E) Quantitative analysis of PCNA staining (yellow arrows), calculated as number of positive cells per mm². (F) Relative expression of PCNA assessed by qPCR in HCS-2/8 cells treated for 72 hours with TNF at 10, 30, 100, 300 ng/ml concentrations (n=3). (G) Western blot analysis of SOX9 and PCNA expressions in HCS-2/8 cells treated with TNF (100 ng/ml). (H, I) Quantification of SOX9 and PCNA expressions by three independent Western blot experiments. (J, K) Quantitative analysis of TRAF2 staining (yellow arrows), calculated as number of positive cells per mm². Error bars indicate mean ± SE. Students t-test was used to analyze differences between groups.
Article Snippet: Next, slides were incubated with anti-humanin antibody (NB100-56877; Novus Biologicals, Littleton, Colorado, USA), anti-proliferating cell nuclear antigen (PCNA) antibody (ab-18197; Abcam, Cambridge, United Kingdom), anti-SOX9 antibody (ab-5355; Sigma-Aldrich, Burlington, MA, USA), and anti-TRAF2 antibody (NB100-56173SS; Novus Biologicals, Littleton, Colorado, USA) overnight at 4°C, 1:300 diluted for all antibodies.
