Abstract:
Objective To study the effects of tetramethylpyrazine(TMP) on the expression of nuclear factor-kappa B(NF-?B) induced by advanced glycation end products(AGEs) in retinal pigment epithelial(RPE).Methods The expressions of NF-?B were detected by immunohistochemical method when the RPE cells were cultured with different concentrations of AGEs in different time points.Results With the increasing of concentrations of AGEs,the expression of NF-?B in RPE was increased gradually.The expression of NF-?B in RPE was higher when the cells were cultured with AGEs for 24 h than that of other time points.With the increasing of the concentration of TMP,the expression of NF-?B in RPE was decreased gradually.Conclusion The AGEs can induce the expression of NF-?B in RPE,and the TMP can prevent the effects of AGEs in a concentration dependent manner.
