Anti-Inflammatory and Antiosteoclastogenic Activities of Parthenolide on Human Periodontal Ligament Cells In Vitro

Figure 6

Effect of PTL on osteoclast gene expression. After coculturing with differently treated hPDLCs, total RNA was collected from RAW 264.7 cells. Gene expression was measured by RT-PCR and the expression of the target gene was first normalized to β-actin and then further converted to the percentage of the control (coculture with hPDLCs only). Error bars indicate mean ± SEM (). versus the control while versus the LPS-treated hPDLCs group.
