ADAMTS-7 Exhibits Elevated Expression in Cartilage of Osteonecrosis of Femoral Head and Has a Positive Correlation with TNF-α and NF-κB P65

Figure 5

ADAMTS-7 and Phospho-NF-κB P65 are upregulated in ONFH patients compared to FNF patients. (a) ADAMTS-7 expression of articular cartilage of FNF patients and ONFH patients, assayed by immunohistochemistry. (b) Phospho-NF-κB expression in FNF group and ONFH group, examined by immunohistochemistry. The ONFH group exhibits high expression of Phospho-NF-κB, and the FNF articular cartilage shows rare Phospho-NF-κB expression. (c) Quantitative analysis of ADAMTS-7 area of FNF and ONFH group by average optical density (, ).
