Abstract

Excessive alcohol consumption induces oxidative stress and lipid accumulation in the liver. Mitochondria have long been recognized as the key target for alcoholic liver disease (ALD). Recently, the artificial mitochondria-targeted antioxidant MitoQ has been used to treat ALD effectively in mice. Here, we introduce the natural mitochondria-targeted antioxidant demethyleneberberine (DMB), which has been found in Chinese herb Cortex Phellodendri chinensis. The protective effect of DMB on ALD was evaluated with HepG2 cells and acutely/chronically ethanol-fed mice, mimicking two common patterns of drinking in human. The results showed that DMB, which is composed of a potential antioxidant structure, could penetrate the membrane of mitochondria and accumulate in mitochondria either in vitro or in vivo. Consequently, the acute drinking-caused oxidative stress and mitochondrial dysfunction were significantly ameliorated by DMB. Moreover, we also found that DMB suppressed CYP2E1, hypoxia inducible factor α, and inducible nitric oxide synthase, which contributed to oxidative stress and restored sirtuin 1/AMP-activated protein kinase/peroxisome proliferator-activated receptor-γ coactivator-1α pathway-associated fatty acid oxidation in chronic ethanol-fed mice, which in turn ameliorated lipid peroxidation and macrosteatosis in the liver. Taking these findings together, DMB could serve as a novel and potential therapy for ALD in human beings.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
