Figure 4.
Effect of IL-1β (1 ng/mL) on resistin mRNA expression (a) and protein levels (b) in PDL fibroblasts after 1 day as determined by qPCR (n = 9/group) and ELISA (n = 6/group), respectively. Untreated cells served as a control. (c) Effect of resistin (100 ng/mL) on IL-6 and IL-8 mRNA expression in PDL cells (n = 6/group). Results are expressed as the mean ± SD. ∗Significant difference (p < 0.05).
