(a) Ethanol inhibition of SAA1-induced MCP-1 expression is Notch-dependent. Monocyte chemoattractant protein-1 (MCP-1) mRNA levels in HCAEC following treatments (24 hr) as indicated; EtOH (25 mM), DAPT (10 μM), DLL4 (1 μg/ml), SAA1 (1 μM). (b) MCP-1 mRNA expression following SAA1 treatment +/− EtOH in HCAEC with/without N1 and/or N4 knockdown.
(c) Ethanol inhibition of SAA1-induced monocyte adhesion is Notch-dependent. THP-1 monocyte adhesion to HCAEC following treatments as above. Data are mean ± SEM, n=3 *P< 0.05, **P< 0.01 vs Control or as indicated, # P<0.05 vs SAA1. (d) THP-1 adhesion following SAA1 treatment +/− EtOH in HCAEC with/without N1 and/or N4 knockdown. (e) Adhesion of primary human monocytes to HCAEC following treatments as above. Data are mean ± SEM, n=3–4. *P< 0.05, **P< 0.01 vs Control or as indicated; #P<0.01 vs SAA1 alone.
