Nobiletin Decreases Inflammatory Mediator Expression in Tumor Necrosis Factor-Stimulated Human Periodontal Ligament Cells

Figure 2

Effects of nobiletin on TNF-induced CXCL10, CCL2, and IL-8 production in HPDLCs. HPDLCs were cultured with TNF (10 ng/ml) and nobiletin (12.5, 25, 50, or 100 μM) for 24 hours. The amounts of CXCL10, CCL2, and IL-8 in the supernatants were determined using their respective ELISA kits. Bars represent the (SD) of data from three independent experiments. : significantly different from the result for the TNF-stimulated HPDLCs that were not treated with nobiletin.
