Abstract: Objective: To investigate how endothelin-1 affects the expression of tumor necrosis factor (TNF-α) in periodontal ligament stem cells (PDLSCs). Methods: The PDLSCs were stimulated with endothelin-1 (1, 10, 100nmol/L) for 12, 24, and 72 hours. The untreated PDLSCs served as normal control. The effect of ET-1 stimulation on TNF-α protein levels was evaluated by ELISA and Western blot. Results: The TNF-α protein levels were enhanced by ET-1 stimulation in a dose-dependent and time-course manner. Conclusion: These results indicate that ET-1 is involved in the regulation of TNF-α expression in PDLSCs and suggest that ET-1 signaling may be a therapeutic target for treating TNF-α-dependent inflammatory responses.
