Abstract

Abstract: PURPOSE: To investigate the expression and significance of chemokines CCL21, E-selectins and heat shock protein 90 (Hsp90) in periodontal tissues of rats with experimental periodontitis. METHODS: Forty 10-week-old male Wistar rats were significantly randomly divided into 4 groups with 10 rats in each group. Periodontitis models were established in groups A, B and C, and the rest were 10 blank control groups. Rats in group A, B and C were sacrificed at 4, 8 and 12 weeks after basic periodontal treatment, and the periodontal tissues of the first and second molars were taken for CCL21, E-selectins and Hsp90 protein expression detection. SPSS 25.0 software package was used to analyze the data. RESULTS: The levels of periodontal attachment in group A, B and C were higher than those in the control group(P< 0.05). The levels of periodontal attachment, CCL21, E-selectins, Hsp90 mRNA and protein expression in periodontal tissues increased first and then decreased(P< 0.05). The levels of periodontal attachment, CCL21, E-selectins, Hsp90 mRNA and protein expression in group B and C were significantly higher than those in group A(P< 0.05). The levels of periodontal attachment, CCL21, E-selectins, Hsp90 and relative protein expression in periodontal tissues of group C were significantly lower than those of group B(P< 0.05). CONCLUSIONS: The expression of CCL21, E-selectins and Hsp90 is up-regulated in periodontitis tissues. With local periodontal treatment, the expression level of CCL21, E-selectins and Hsp90 gradually decreases.
