  • The Effect and Mechanism of Naringenin on Production of Chemokines in Human Bronchial Epithelial Cells

    ObjectiveTo investigate the effects of naringenin on the production of chemokines and its mechanism in human bronchial epithelial (HBE) cells. MethodsHBE cells were divided into a control group, a TNF-αgroup, a low-dose naringenin group, a moderate-dose naringenin group and a high-dose naringenin group. The Naringenin groups were incubated with different doses of naringenin (10, 5 and 2.5μmol/L, respectively) for 2 h. Then the naringenin groups and the TNF-αgroup were incubated with TNF-α. After 24 h of incubation, the levels of eotaxin and RANTES were determined by ELISA method, and IκBαdegradtion was detected by Western blot method. After incubated with TNF-αfor 30 min, NF-κB DNA-binding activity was detected by EMSA method. ResultsCompared with the control group, the levels of eotaxin and RANTES were significantly increased in the HBE cells stimulated with TNF-α. Naringenin had inhibitory effects on the expression of these chemokines. Naringenin abolished IκBαdegradation and reduced the DNA-binding activity of NF-κB. ConclusionNaringenin may inhibit the production of chemokines through inhibiting NF-κB pathway.
