| Popis: | The current work examines the expression of acute phase genes in a murine-derived bone marrow stromal cell model (BMS2) which exhibits adipocyte and osteoblast characteristics and supports lymphopoiesis in vitro. Each of these physiologic processes is responsive to inflammatory events such as endotoxemia. Exposure of BMS2 cells to pro-inflammatory cytokines induced the expression of the serum amyloid A and complement factor B. During adipocyte differentiation, expression of complement C3, complement factor D (adipsin), and angiotensinogen increased in a time dependent manner. The bone metabolic steroid, 1,25 dihydroxy vitamin D3, specifically induced complement C3 expression in a time- and dose-dependent manner. Based on gel retention analysis, BMS2 nuclear extract contained proteins recognizing specific response elements from the complement C3, angiotensinogen, and complement factor B promoters. These results suggest that the bone marrow's repertoire of acute phase proteins is dependent on the stromal cell's phenotype or activation state. |
