Abstract
Objective To observe the effect of stimulation with LPS on the expression of high mobility group box1(HMGB1) in murine peritoneal macrophages.Methods The peritoneal macrophages of normal mice were isolated and stimulated with LPS for 4,8,12,18,24 and 36 h respectively,then determined for transcription level of HMGB1 mRNA by RT-PCR and for expression level of HMGB1 protein by Western blot.The time-response relationship between LPS stimulation and HMGB1 release was observed.Results The transcription level of HMGB1 mRNA showed no significant change 4~18 h,while increased significantly 24 h and showed significant difference with those of control 24 and 36 h after LPS stimulation.However,the expression level of HMGB1 protein increased significantly from 18 h until 36 h after LPS stimulation.Conclusion LPS showed a time-dependent promoting effect on the expression of HMGB1 in murine peritoneal macrophages.
