Abstract

Abstract: Objective To investigate the inhibition of house dust mite induced oxidative stress with human bronchial epithelial cell line BEAS-2B by aldose reductase inhibitor (ARIs). Methods BEAS-2B was divided into control group, model group, NF-κB inhibitor group (PDTC group) and ARIs intervention group (ARIs group). Oxidative stress reaction (MDA and ROS content, SOD activity) was detected by ELISA. The contents of IL-5, IL-13 and IFN-γ were measured by ELISA. MTT was used to detect cell viability. Cell apoptosis was detected by flow cytometry. The expressions of NF-κB, NF-κB P65 and P38 MAPK proteins were detected by Western blot. Results SOD activity, IFN-γ content and cell survival rate in model group were lower than those in control group (P＜0.05), MDA, IL-5, IL-13 content and cell apoptosis rate were higher than those in control group (P＜0.05). Compared with model group, SOD activity, IFN-γ content and cell survival rate in PDTC and ARIs groups were increased(P＜0.05), MDA, IL-5, IL-13 content and cell apoptosis rate were decreased (P＜0.05). Compared with control group, the expression of NF-κB, NF-κB P65 and P38 MAPK protein in model group was significantly increased(P＜0.05). The expression of NF-κB, NF-κB P65 and P38 MAPK protein in PDTC group and ARIs group were significantly decreased (P＜0.05). Conclusions Aldose reductase inhibitors improve the oxidative stress response of human bronchial epithelial cells induced by house dust mites, promote the proliferation of BEAS-2B cells and inhibit apoptosis.
