Figure 1. Oncostatin M <t>(OSM)–induced</t> expression of CCL13. A and B, Normal dermal fibro- blasts (nDF), normal lung fibroblasts (nLF), normal cervical fibroblasts (nCF), and normal synovial fibroblasts (nSF) were treated with 10 ng/ml of OSM for the indicated periods of time. A, Levels of CCL2, CCL13, and CCL11 mRNA were determined by RNase protection assay. Results are representative of 3 independent experiments. B, The amounts of CCL13 and CCL2 in culture supernatants were determined by enzyme-linked immunosorbent assay <t>(ELISA).</t> Values are the mean SD (n 3). P 0.05 versus control. C, Primary human blood neutrophils were stimulated with 10 ng/ml of granulocyte–macrophage colony-stimulating factor (GM-CSF) for 3 hours. The amounts of OSM in culture supernatants were determined by ELISA. Values are the mean SD (n 3). P 0.05 versus control. D, Culture supernatants (SNs) from untreated neutrophils or neutrophils stimulated with GM-CSF for 3 hours were transferred onto normal SFs. The contribution of OSM was evaluated by additional application of blocking antibodies to OSM or control antibodies (ctrl. Ab). The amounts of CCL13 produced in normal SF culture supernatants were then determined by ELISA. Values are the mean SD (n 4). P 0.05 versus control; d P 0.05 versus antibody control.

Lysates were subjected to Western blot analysis, using antibodies specific for the indicated proteins. The blots were stripped and reprobed with antibodies recognizing the proteins irrespective of their activation status or with loading control antibodies. B, Normal SFs were stimulated with OSM as indicated. Western blots of lysates were stained with the antibodies indicated. C, Normal SFs, normal cervical fibroblasts (nCF), normal lung fibroblasts (nLF), and normal dermal fibroblasts (nDF) were stimulated with 10 ng/ml of OSM.

Comparison of oncostatin M (OSM)–, interleukin-6 (IL-6)/soluble IL-6 receptor (sIL-6R)–, IL-1–, and tumor necrosis factor (TNF)–induced signal transduction, showing a potential role of phosphorylated (pY) STAT-5 in CCL13 induction. A, Normal synovial fibroblasts (nSF) were treated with 10 ng/ml of OSM, 200 units/ml of IL-6/0.5 g of sIL-6R, 10 ng/ml of IL-1, or 10 ng/ml of TNF. Lysates were subjected to Western blot analysis, using antibodies specific for the indicated proteins. The blots were stripped and reprobed with antibodies recognizing the proteins irrespective of their activation status or with loading control antibodies. B, Normal SFs were stimulated with OSM as indicated. Western blots of lysates were stained with the antibodies indicated. C, Normal SFs, normal cervical fibroblasts (nCF), normal lung fibroblasts (nLF), and normal dermal fibroblasts (nDF) were stimulated with 10 ng/ml of OSM. Cell lysates were analyzed as described in B. D, Normal SFs were transfected with control or STAT-5 small interfering RNA (siSTAT5).
