[Toxic effect of butenolide on chondrocyte differentiation and the protective effect of selenium].

Abstract

OBJECTIVE To study the effect of butenolide (BUT) on cultured chondrocytes differentiation and the possible protective effects of selenium (Se). METHODS Ex-vivo cultured chondrocytes were divided into six groups: (1) Control group (without BUT and Se); (2) Se 0.1 microg/ml control group; (3) BUT 0.1 microg/ml group; (4) BUT 1.0 microg/ml group; (5) BUT 5.0 microg/ml group; and (6) BUT 1.0 microg/ml + Se 0.1 microg/ml group. The expression of collagen II (Col II), collagen X (ColX), basic fibroblast growth factor (bFGF), and parathyroid hormone-related peptide (PTHrP) in (or around) chondrocytes in all groups were analyzed by immunohistochemistry. RESULTS The expressions of Col II in 1.0 microg/ml BUT group and 5.0 microg/ml BUT group were significantly lower than those in the control group (P < 0.05). The expression of Col II in 1.0 microg/ml BUT + Se group were significantly higher than those in the 1.0 microg/ml BUT group and 5.0 microg/ml BUT group (P < 0.05). The expressions of bFGF and PTHrP of BUT groups were significantly higher than those in the Se and control groups (P < 0.05). No expression of ColX was observed in all groups. CONCLUSION BUT can affect the collagen II synthesis of the chondrocytes. Selenium supplementation may play a protective role.
