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

Figure 3

Effects of nobiletin on TNF-induced MMP1, MMP3, and TIMP1 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 MMP1, MMP3, and TIMP1 in the supernatants were determined using their respective ELISA kits. Bars represent the of data from three independent experiments. : significantly different from the result for the TNF-stimulated HPDLCs that were treated without nobiletin.
