Sion and promoted NF-B p65 protein translocation from cytoplasmic fractions to nuclear fractions. Furthermore, THSG remedy substantially restored the IB degradation (Figure 3B) and NF-B p65 nuclear translocation (Figure 3C) in P. gingivalis-infected brain endothelial cells. Specifically, the expressionexpression levels of IB (Figure 3B) and NF-B p65 (Figure 3C) proteins in cells THSG treatment had been not considerably distinct from cells within the handle group. Furthermore, P. gingivalis infection improved NF-B p65 DNA-binding activity proximately two.five fold (Figure 3D). The NF-B transcriptional activity of cells infected Antioxidants 2022, 11, 740 ten of 21 P. gingivalis within the presence of THSG treatment was significantly decreased (Figure Moreover, the expression levels of IB, NF-B p65 proteins, and NF-B p65 DNAlevels of IB (Figure by incubation of heat-killed bacteria. ing activity had been not affected3B) and NF-B p65 (Figure 3C) proteins in cells with THSG treatmentwere not considerably unique from cells in the handle group.Figure three.

The NF-B transcriptional activity of cells infected with P. gingivalis within the presence of THSG remedy was drastically decreased (Figure 3D). Also, the expression levels of IB, NF-B p65 proteins, and NF-B p65 DNA-binding activity were not affected by incubation of heat-killed bacteria. 3.four. The Reduction in ROS and NF-B Activation Is Accountable for the Anti-Inflammatory and Antiapoptotic Properties of THSG in P. gingivalis-Infected Brain Endothelial Cells Subsequent, we additional confirmed no matter whether the anti-inflammatory and antiapoptotic effects of THSG are ROS-dependent. The effects of ROS scavenger N-Acetyl-L-cysteine (NAC) and NADPH inhibitor apocynin were used to evaluate using the protective effects of THSG. To identify the optimal concentration of apocynin for our study model, we treated brain endothelial cells with several concentrations of apocynin (50.
