Abstract excerpt
Collagenase 3 degrades collagen fibrils and is necessary for bone resorption. Cortisol increases collagenase 3 mRNA in osteoblasts by stabilizing collagenase 3 transcripts. To understand mechanisms involved, we used RNA electrophoretic mobility shift assay and RNA turnover studies. Cortisol increased the binding of Ob cell cytosolic extracts to AU-rich sequences in the collagenase 3 3'-untranslated region (UTR)....
