Abstract:
Objective:To investigate whether the inhibitory effect of berberine (BBR) on inflammation and apoptosis of human dental pulp stem cells (hDPSCs) induced by lipopolysaccharide (LPS) is related to its upregulation of microRNA (miR)-23a.Methods:The 3rd to 4th generation hDPSCs with good growth were taken and randomly divided into the blank control group, LPS group, LPS+ BBR group, LPS+ miR-NC mimics group, LPS+ miR-23a mimics group, and LPS+ BBR+ miR-23a inhibitors group according to the experimental requirements. The expression levels of miR-23a mRNA in each group were detected by real-time fluorescence quantitative polymerase chain reaction (RT-qPCR), and the expression levels of interleukin-1 β(IL-1β), interleukin-6 (IL-6), and tumor necrosis factor -α (TNF-α) in the cell supernatants of each group were detected by enzyme-linked immunosorbent assay (ELISA). The apoptosis rate of cells in each group was detected by flow cytometry, and the expression level of Cleaved caspase-3 of apoptosis-related proteins in each group was detected by Western blot.Results:Compared with the LPS group, different concentrations of LPS+ BBR groups could significantly reduce the expression levels of cellular inflammatory factors IL-1β, IL-6, TNF-α, apoptosis rate, and apoptotic protein Cleaved caspase 3 in a dose-dependent manner (all P<0.05). Compared with the LPS group, the expressions of the cellular inflammatory factors IL-1β, IL-6, TNF-α, apoptosis rate and apoptotic protein Cleaved caspase in the LPS+ miR-23a mimics group, the LPS+ BBR group and the LPS+ BBR+ miR-23a inhibitors group were lower (all P<0.05). Compared with the LPS+ miR-NC mimics group, the cellular inflammatory factors IL-1β, IL-6, TNF-α, apoptosis rate and the expression of apoptotic protein Cleaved caspase 3 in the LPS+ miR-23a mimics group and the LPS+ BBR group were all lower (all P<0.05). Compared with the LPS+ BBR group, the inflammatory factors IL-1β, IL-6, TNF-α, apoptosis rate and the expression of apoptotic protein Cleaved caspase 3 in the LPS+ BBR+ miR-23a inhibitors group were all higher (all P<0.05). Conclusions:BBR can inhibit the inflammatory and apoptotic responses of LPS-induced hDPSCs, which is related to its upregulation of miR-23a expression.
