Abstract：This study was performed to investigate the effects of Arbutin(Ar)on oxidative stress,apoptosis level and inflammatory response of H9c2 cardiomyocytes induced by lipopolysaccharide(LPS).H9c2 cardiomyocytes were randomly divided into blank control group,lipopolysaccharide group(LPS),LPS+Ar(25 µmol/L)group,LPS+Ar(50 µmol/L)group,LPS+Ar(100 µmol/L)group and Ar(50 µmol/L)group.CCK-8 was used to detect the cell viability of H9c2 cardiomyocytes after LPS treatment and Ar treatment;DCFH-DA fluorescence labeling was used to detect the ROS levels of H9c2 cardiomyocytes;flow cytometry was applied to detect cell apoptosis rate;Western blot was used to detect the expression of apoptosis-related proteins(Caspase-3)and inflammatory proteins(IL-1β and TNF-α).Data showed that compared with the LPS group,the cell viabilities were recovered after Ar treatment.The level of oxidative stress markers(ROS),apoptosis rate,and inflammatory factor levels(IL-1β and TNF-α)in the LPS+Ar groups were significantly reduced compared with the LPS group(P<0.05).In conclusion,Ar can alleviate the damage,apoptosis,oxidative stress and inflammatory response of LPS-induced H9c2 cardiomyocytes.
