OBJECTIVE
To compare the effects of different approaches to establishing rat models of acute liver failure (ALF).
METHODS
Sixty-eight Sprague-Dawley rats were randomly divided into 3 groups for establishing ALF models using 3 different approaches, namely conventional hepatectomy for resecting 90%
Lipopolysaccharide (LPS) is implicated in the pathology of acute liver injury and can induce lethal liver failure when simultaneously administered with D-galactosamine (D-GalN). At the present time, nonlethal liver failure, the liver injury of clinical implication, is incompletely understood
BACKGROUND
Sphingosine kinase 1 (SphK1)/sphingosine-1-phosphate (S1P)/sphingosine-1-phosphate receptors (S1PRs) signaling plays a key role in inflammatory responses. Lei et al. showed that SphK1 inhibition presented a hepatoprotective effect on acute liver damage via decreasing hepatic high-mobility
OBJECTIVE
To investigate the effects of Recql5 deficiency on liver injury induced by lipopolysaccharide/D-galactosamine (LPS/D-Gal).
METHODS
Liver injury was induced in wild type (WT) or Recql5-deficient mice using LPS/D-Gal, and assessed by histological, serum transaminases, and mortality analyses.
Urinary trypsin inhibitor (UTI), a serine protease inhibitor, has been widely used for patients with inflammatory disorders including disseminated intravascular coagulation, shock, and pancreatitis in Japan. Our recent studies using UTI-null (-/-) mice have shown that UTI protects against systemic
BACKGROUND
Fulminant hepatic failure (FHF) has a high mortality resulted from massive hepatic apoptosis and haemorrhage necrosis; it is required to develop a valid therapy directed towards hepatocyte protection and regeneration. Pim-3, a hepatic growth stimulator, belongs to the serine/threonine
OBJECTIVE
To investigate the role of CD38 in lipopolysaccharide (LPS)/D-galactosamine (D-GalN)-induced acute hepatic injury in mice and explore the potential mechanism.
METHODS
A mouse model of acute hepatic injury was induced by an intraperitoneal injection (i.p.) of D-GalN and LPS. C57BL/6
Interleukin (IL)-19 is a cytokine clustered in the IL-20 cytokine superfamily with both anti-inflammatory and pro-inflammatory aspects depending on the etiology of inflammatory disease. The function of IL-19 has been evaluated in cutaneous and inflammatory bowel diseases, but has not been studied in
The aim of this study was to evaluate the effect of insulin-like growth factor-I (IGF-I) on lethality and liver function in experimental acute liver failure. Intravenous co-administration of D-galactosamine (GalN) and lipopolysaccharide (LPS) to rats induced high mortality and marked increases in
Recent studies have suggested an association between tumor necrosis factor-alpha (TNF-alpha) and the development and progression of acute liver failure. To investigate the role of TNF-alpha in the mechanism of massive hepatic necrosis, we studied a mouse model of TNF-alpha and D-galactosamine (GalN)
To elucidate whether leukocyte cell-derived chemotaxin 2 (LECT2) controls the progression of staphylococcal enterotoxin A (SEA)-induced toxicity, we examined the role of LECT2 in a mouse model. Almost all the C57BL/6J (B6) mice survived for 72 h after the injection of 0.1 μg of SEA and 20 mg of
Natural killer-T (NKT) cells are rich in the liver. However, their involvement in liver injury is not fully understood. We developed here a new murine model of NKT-cell-activation-associated liver injury, and investigated a role of tumor necrosis factor alpha (TNF-alpha) and Fas in pathogenesis. We
Mallotus repandus (M. repandus) is traditionally used to treat muscle pain, itching, fever, rheumatic arthritis, and a variety of liver disorders. The aim of the present work was to evaluate the hepatoprotective activity and the antioxidant potential of the ethyl acetate stem extract
Polyethylene glycol (PEG) is attached to proteins in order to increase their half-life in circulation and reduce their immunogenicity in vivo. The present study was conducted to examine whether two different sizes of PEGylated bovine lactoferrin (40k- and 20k-PEG-bLf) would enhance the protective
Organoselenium compounds display important antioxidant activity and many biological activities interesting from pharmacological point of view. The aim of this study was to evaluate the hepatoprotective effect of p-methoxyl-diphenyl diselenide, a disubstituted diaryl diselenide, on acute liver injury
