Comparison of experimental models of alcoholic liver disease
Models | Animal model | Characteristics | Advantages and disadvantages |
Lieber-DeCarli liquid diet[27,28] | Rat/mice | Chronic ethanol feeding (4-12 wk) | Easy to perform |
Marked elevation of ALT | |||
Short term feeding with no mortality rate | |||
No liver fibrosis | |||
Rat/mice | Chronic ethanol feeding + single/multiple binges (4-6 wk) | Easy to perform | |
Marked elevation of ALT and marked steatosis | |||
Long term feeding + multiple binges with a high mortality rate | |||
No liver fibrosis | |||
Rat/mice | + Second hit: DEN, LPS, CCl4, APAP (4-12 wk) | Easy to perform | |
Marked elevation of ALT and marked steatosis | |||
Long term feeding + multiple binges + injection with a high mortality rate | |||
Liver fibrosis | |||
Ethanol ad libitum feeding[27,28] | Mice | Oral alcohol in drinking water (10 d/1-2 wk) | Easy to perform |
Minimal elevation of ALT and mild steatosis | |||
Short-or long-term feeding with no mortality rate | |||
No liver fibrosis | |||
The Tsukamoto-French model[27,28] | Rat/mice | Intragastric infusion (2-3 mo) | Difficult to perform |
Requirement for intensive medical care | |||
Marked elevation of ALT and steatosis | |||
Long-term feeding with a high mortality rate | |||
Mild liver fibrosis | |||
The NIAA model[47] | Mice | LDE + single ethanol binge | Cost and time efficient |
High blood alcohol levels | |||
Liver injury | |||
Inflammation | |||
Fatty liver | |||
Rat /mice | LDE + 3 ethanol binges | Cost and time efficient | |
Increased blood alcohol levels | |||
Augmented liver injury | |||
Increases in ERK1/2 | |||
Ethanol + CCl4 treatment[106] | Mice | 4% ethanol liquid diet + 2 times IP CCl4 injection per week (8 wk) | Easy to perform |
Toxic components | |||
Elevated acetaldehyde levels | |||
Liver fibrosis |
Lieber-DeCarli liquid diet with different variants, ethanol ad libitum feeding and the Tsukamoto-French and the NIAA model. ALT: Alcoholic liver disease; DEN: Diethylnitrosamine; LPS: Lipopolysaccharide; CCl4: Carbon tetrachloride; APAP: Acetaminophen; LDE: Lieber-De Carli ethanol diet; IP: Intraperitoneal.
