Abstract：Objective: To explore whether miR-153-3p can improve the inflammatory response of human periodontal ligament stem cells (hPDLSCs) induced by lipopolysaccharide (LPS) by targeting regulates chitinase 3-like protein 1 (CHI3L1). Methods: The hPDLSCs were isolated and cultured, and inflammatory cell models were established using LPS treatment and transfected with miR-NC, miR-153-3p mimics, si-NC, si-CHI3L1, and miR-153-3p mimics+pc-NC, miR-153-3p mimics+pcDNA-CHI3L1. 48 h after transfection, the expressions of miR-153-3p and CHI3L1 mRNA in the cells of each group were detected by qRT-PCR, the levels of IL-6, IL-1β and TNF-α in the cell supernatant were detected by ELISA, cell apoptosis was detected by flow cytometry, the expression of CHI3L1 protein in cells was detected by Western Blot, the targeting relationship between miR-153-3p and CHI3L1 was detected by dual-luciferase reporter gene assay. Results: The expression of miR-153-3p was down-regulated in hPDLSCs after LPS treatment (P<0.05), while the expressions of CHI3L1 mRNA and protein were significantly up-regulated (P<0.05); over-expression of miR-153-3p or inhibition of CHI3L1 expression could reduce the levels of IL-6, IL-1β and TNF-α in LPS-induced hPDLSCs, down-regulate the expressions of CHI3L1 mRNA and protein, and reduce the apoptosis rate, and the differences were statistically significant (P<0.05). The dual-luciferase reporter gene assay confirmed that miR-153-3p could targeting regulates the expression of CHI3L1 (P<0.05). In addition, the over-expression of CHI3L1 could significantly reverse the inhibitory effects of the over-expression of miR-153-3p on LPS-induced apoptosis and inflammatory response of hPDLSCs (P<0.05). Conclusion: MiR-153-3p can reduce the LPS-induced inflammatory response and apoptosis of hPDLSCs by targeting regulates CHI3L1 expression.
