Increased hepatic iron content may be observed in patients with chronic hepatitis C infection, and may contribute to disease severity. The presence of hemochromatosis gene mutations is associated with increased hepatic iron accumulation and may lead to accelerated disease progression. Hepatic iron depletion has been postulated to decrease the risk of hepatocellular carcinoma in patients with ci...

BACKGROUND Hepatic encephalopathy is an extra hepatic complication of impaired liver function and is manifested as neuropsychiatric signs and symptoms associated with acute or chronic liver disease in the absence of other neurological disorders. There are numerous factors of hepatic encephalopathy. The main objective of this study was to analyse the precipitating factors of hepatic encephalopat...

The oncogene c-myc encodes a transcription factor that has long been considered essential to liver regeneration, the process by which fully differentiated hepatocytes proliferate in an attempt to maintain a normal functional mass in response to hepatic injury. Experimental liver regeneration can be induced upon 70% partial hepatectomy and is accompanied by an increase in c-myc expression accomp...

OBJECTIVE Obesity induces a program of systemic inflammation that is implicated in the development of many of its clinical sequelae. Hepatic inflammation is a feature of obesity-induced liver disease, and our previous studies demonstrated reduced hepatic steatosis in obese mice deficient in the C-C chemokine receptor 2 (CCR2) that regulates myeloid cell recruitment. This suggests that a myeloid...

BACKGROUND & AIMS Toll-like receptor 4 (TLR4) signaling is activated through 2 adaptor proteins: MyD88 and TIR-domain containing adaptor-inducing interferon-β (TRIF). TLR4 and MyD88 are crucial in nonalcoholic steatohepatitis (NASH) and fibrosis. However, the role of TRIF in TLR4-mediated NASH and fibrosis has been elusive. This study investigated the differential roles of TRIF in hepatic steat...

The adherence of Candida albicans was studied in situ by using the perfused mouse liver model. After exhaustive washing, 10(6) C. albicans were infused into mouse livers. At the time of recovery, 62 +/- 5% (mean +/- standard error of the mean) of the infused C. albicans were recovered from the liver and 14 +/- 3% were recovered from the effluent for a total recovery of 76 +/- 4%. This indicates...

C57BL/6 mice are susceptible to diet-induced atherosclerosis, whereas BALB/c mice are resistant. The susceptibility of C57BL/6 mice has been linked to decreased plasma HDL cholesterol in response to a diet containing fat, cholesterol, and cholic acid. Feeding C57BL/6 mice a diet consisting of fat and cholesterol, but no cholic acid, increased plasma high density lipoprotein (HDL) cholesterol. T...

Liver fibrosis can progress to cirrhosis and result in serious complications of liver disease. The pathogenesis of liver fibrosis involves the activation of hepatic stellate cells (HSCs), the underlying mechanisms of which are not fully known. Emerging evidence suggests that the classic histone deacetylases play a role in liver fibrosis, but the role of another subfamily of histone deacetylases...

Both the catalytic protein (C) and the guanine nucleotide-binding regulatory protein (G/F) of rabbit hepatic adenylate cyclase were solubilized in active form in sodium cholate at high ionic strength. Upon precipitation by (NH4)*S04, C was selectively aggregated such that it was largely excluded from Ultrogel AcA 34 when chromatographed in cholate solution at high ionic strength. G/F eluted wit...
