Figure Lengend Snippet: (a) αSMA mRNA levels in HCAEC treated with TGFβ1 (10 ng/ml) or exposed to hypoxic conditions (5% O 2 ), in the absence or presence of moderate dose EtOH (25 mM, green bars) or high dose EtOH (100 mM, red bars) +/- the γ-secretase inhibitor DAPT (20 μM). (b) αSMA and fibronectin (FN) mRNA levels in HCAEC treated with TGFβ1 +/- the Notch ligand DLL4 (3 μg/ml) in the absence or presence of DAPT (20 μM). Data are mean±SEM, n=3. *p<0.05 vs control (no treatment), #p<0.05 vs TGFβ1 or hypoxia.

Article Snippet: Where indicated, cells were treated with Notch inhibitor DAPT (20 μM, Cat. #2634, Tocris,) or Notch ligand DLL4 (2 μg/ml, Cat. # 1506-D4, R&D Systems).

Techniques: Control

Figure Lengend Snippet: HCAEC were treated with inflammatory cytokines (IL1β + TGFβ1) in the absence or presence of moderate dose ethanol (25 mM EtOH) or high dose ethanol (100 mM EtOH), with or without the gamma secretase inhibitor DAPT (20 μM), before Cdh5 expression was determined by immunocytochemistry. (a) Representative immunofluorescence images from 2 separate experiments, and (b) cumulative quantitative data of Cdh5 fluorescent staining. Data are mean±SEM, n=6. *p<0.05 vs control (no treatment, grp 1), #p<0.05 vs IL1β + TGFβ1 (grp 2).

Article Snippet: Where indicated, cells were treated with Notch inhibitor DAPT (20 μM, Cat. #2634, Tocris,) or Notch ligand DLL4 (2 μg/ml, Cat. # 1506-D4, R&D Systems).
