Abstract:
OBJECTIVE:To determine whether 17beta-oestradiol (E2) modulates interleukin (IL) 1beta-induced proteoglycan degradation in chondrocytes, and to analyse the part played by metalloproteinases (MMPs) in this process. METHODS:Primary cultured rabbit articular chondrocytes were prepared and treated with 10 ng/ml IL1beta combined or not with 0.1-10 nM E2. Neosynthesised proteoglycans (PGs) were evaluated after incorporation of [(35)SO(4)]sulphate and further analysed after chromatography on a Sepharose 2B column. Chondrocyte mRNA levels of aggrecan, MMP-1, -3, -13, and tissue inhibitor of metalloproteinase-1 (TIMP-1) were studied by northern blot. MMP-1 activity was measured by zymography. MMP-1 gene transcription was studied by transient transfection of chondrocytes with an MMP-1-luciferase construct. RESULTS:E2 modulated the IL1beta-induced total sulphated PGs in rabbit articular chondrocytes, which decreased as the E2 concentration was increased. At a low concentration (0.1 nmol/l) E2 counteracts the IL1beta-induced decrease in sulphated PG, while at high concentration (10 nmol/l) E2 enhances the IL1beta effects. A biphasic E2 effect was also observed on IL1beta-induced disaggregation of PG, 53-58 kDa gelatinolytic activity, and MMP-1, -3, and -13 mRNA levels. In contrast, E2 did not modify the level of aggrecan mRNA and had no effect on TIMP-1 mRNA expression. Finally, simultaneous addition of IL1beta and E2 (0.1-10 nmol/l) did not modify IL1beta-induced MMP-1-luciferase activity, suggesting that E2 effects probably occur at the post-transcriptional level of MMP gene expression. CONCLUSION:Oestrogen concentration may have an inverse effect on IL1beta stimulated proteoglycan degradation and MMP production by chondrocytes.
