Cell preconditioning reduces the expression of proinflammatory proteins. a Expression of NF-κB, COX-2, and IL-1β. HC016 cells and hASCs were exposed to 0.25 mM H₂O₂ for 1 h and lysed 24 h after the insult. b Expression and quantification of NF-κB, COX-2, and IL-1β. Values were normalized to β-actin. At least three different experiments were performed. Data were normalized to control hASCs (dotted line) and expressed as mean ± SD. *p < 0.05, compared with control hASCs, ^#p < 0.05
