摘要
Alcoholic liver disease(ALD)is a growing global health concern,and its early pathogenesis includes steatosis and steatohepatitis.Inhibiting lipid accumulation and inflammation is a crucial step in relieving ALD.Evidence shows that puerarin(Pue),an isoflavone isolated from Pueraria lobata,exerts cardio-protective,neuroprotective,anti-inflammatory,antioxidant activities.However,the therapeutic potential of Pue on ALD remains unknown.In the study,both the NIAAA model and ethanol(EtOH)-induced AML-12 cell were used to explore the protective effect of Pue on alcoholic liver injury in vivo and in vitro and related mechanism.The results showed that Pue(100 mg·kg^(−1))attenuated EtOH-induced liver injury and inhibited the levels of SREBP-1c,TNF-α,IL-6 and IL-1β,compared with silymarin(Sil,100 mg·kg^(−1)).In vitro results were consistent with in vivo results.Mechanistically,Pue might suppress liver lipid accumulation and inflammation by regulating MMP8.In conclusion,Pue might be a promising clinical candidate for ALD treatment.
