Necrostatin-1 Treatment. During a 4d,32% ethanol
exposure protocol, C57BL/6J wild-type (WT)
mice received a once-daily intraperitoneal injection of
necrostatin-1 (1.65 mg/kg) or vehicle (2% dimethyl
sulfoxide in phosphate-buffered saline) before ethanol
(4d,32%) feeding. This concentration/dose regimen
inhibits RIP1 kinase activity in vivo.
Human Liver Samples. Deidentified human liver
biopsy samples from 20 ALD patients and eight
patients with minimal liver pathology were obtained
from the Cleveland Clinic surgical pathology database.
The selection criteria are described in the Supporting
Information. All procedures using deidentified human
liver tissue were approved by the Cleveland Clinic
Institutional Research Board.
