ALD in mice and humans is associated with impaired autophagic flux.
(A,B) Total liver proteins were extracted from pair-fed (PF), chronic alcohol
diet (EtOH), and acute-on-chronic alcohol (EtOH) fed mice (n =
8–10/group) and analyzed by western blotting using β-actin as a
loading control. Protein levels of Beclinl, Atg7, LC3-I, LC3-II, and p62 in
chronic alcohol (A) and in acute-on-chronic alcohol-fed (B) mice. Western
blotting analysis for LC3-I, LC3-II, and p62 from livers of control subjects and
ALD patients (C). mTOR protein levels in mouse livers in chronic alcohol- and in
acute-on-chronic alcohol-fed mice and in ALD patients (D). The densitometry
analysis is shown as bar diagrams. Human liver sample data are representative of
3 control donors and 6–8 patients with cirrhosis and superimposed AH.
