BACKGROUND The liver plays a central role in nutrient and xenobiotic metabolism, but its functionality declines with age. Senior dogs suffer from many of the chronic hepatic diseases as elderly humans, with age-related alterations in liver function influenced by diet. However, a large-scale molecular analysis of the liver tissue as affected by age and diet has not been reported in dogs. METHO...

Cold exposure imposes a metabolic challenge to mammals that is met by a coordinated response in different tissues to prevent hypothermia. This study reports a transcriptomic analysis in brown adipose tissue (BAT), white adipose (WAT) and liver of mice in response to 24 h cold exposure at 8°C. Expression of 1895 genes were significantly (P<0.05) up- or down-regulated more than two fold by cold e...

The molecular mechanisms behind human liver disease progression to cirrhosis remain elusive. Nuclear receptor small heterodimer partner (SHP/Nr0b2) is a hepatic tumor suppressor and a critical regulator of liver function. SHP expression is diminished in human cirrhotic livers, suggesting a regulatory role in human liver diseases. The goal of this study was to identify novel SHP-regulated genes ...

BACKGROUND Pathogenesis and factors for determining progression of alcoholic and non-alcoholic steatosis to steatohepatitis with risk of further progression to liver cirrhosis and cancer are poorly understood. In the present study, we aimed to identify potential molecular signatures for discrimination of steatohepatitis from steatosis. METHODOLOGY AND RESULTS Global microarray gene expression...

Abstract The present study aimed to evaluate a methodology for active surveillance of visceral leishmaniasis by detecting Leishmania DNA in organs wild road-killed animals from November 2016 October 2018 the North Paraná, Brazil. collection points were georeferenced. autopsied and samples bone marrow, lymph node, liver, spleen, ear skin collected. Genomic was extracted subjected PCR amplificati...

Early regulatory events in respect to the embryonic development of the vertebrate liver are only poorly defined. A better understanding of the gene network that mediates the formation of hepatocytes from pluripotent embryonic precursor cells may help to establish in vitro protocols for hepatocyte differentiation. Here, we describe our first attempts to make use of early embryonic explants from ...

BACKGROUND & AIMS Hepatocellular carcinoma develops in patients with chronic hepatitis or cirrhosis via a stepwise accumulation of various genetic alterations. To explore the genetic basis of development of hepatocellular carcinoma in hepatitis C virus (HCV)-associated chronic liver disease, we evaluated genetic variants that accumulate in nontumor cirrhotic liver. METHODS We determined the w...

Toxic liver injury causes necrosis and fibrosis, which may lead to cirrhosis and liver failure. Despite recent progress in understanding the mechanism of liver fibrosis, our knowledge of the molecular-level details of this disease is still incomplete. The elucidation of networks and pathways associated with liver fibrosis can provide insight into the underlying molecular mechanisms of the disea...

Alcohol-related liver disease is a major public health problem, with varying clinical course and often devastating consequences. Its spectrum can vary from alcohol-related fatty liver, alcoholic hepatitis, cirrhosis, hepatocellular carcinoma. Multiple environmental, genetic, socio-economic epigenetic factors are intrinsically involved, affecting behavior progression. Recent advances in genome-w...
