Background
Angelica polysaccharide (AP) is disengaged from the roots of Angelica sinensis. The extensive pathological activities of AP have been discovered in disparate diseases. Nevertheless, the impression of AP in epilepsy (EP) remains unaware. The research attempted to probe the impact of AP on lipopolysaccharide (LPS)-evoked inflammatory injury in HT22 cells.
Conclusions
Data corroboarted that AP mitigated LPS-evoked inflammatory injury through repression of NF-κB and JAK2/STAT3 pathways by regulating miR-10a in HT22 cells.
Methods
AP were exploited to stimulate HT22 cells, cell cytotoxicity was monitored by CCK-8 assay. LPS was utilized to administrate HT22 cells to evoke inflammatory injury, meanwhile the involvements of AP in cell proliferation, apoptosis and inflammatory cytokines productions were examined. MicroRNA-10a (miR-10a) inhibitor and its negative control were one by one transfected into HT22 cells, the effect of miR-10a inhibition on LPS- and AP-treated cells was determined. NF-κB and JAK2/STAT3 pathways were ultimately detected.
Results
AP promoted cell proliferation, inhibited apoptosis and suppressed IL-1β, TNF-α and IL-6 productions in LPS-stimulated HT22 cells. Additionally, AP raised miR-10a expression in HT22 cells administration with LPS. These functions of AP in LPS-disposed cells were conversed by miR-10a suppression. Further, AP interdicted NF-κB and JAK2/STAT3 pathways via enhancing miR-10a. Conclusions: Data corroboarted that AP mitigated LPS-evoked inflammatory injury through repression of NF-κB and JAK2/STAT3 pathways by regulating miR-10a in HT22 cells.
