Thyroid hormone receptor alpha modulates fibrogenesis in hepatic stellate cells.

Objective: Progressive hepatic fibrosis can be considered the final stage of chronic liver disease. Hepatic stellate cells (HSC) play a central role in liver fibrogenesis. Thyroid hormones (TH, e.

A Potential Role for Bile Acid Signaling in Celiac Disease-Associated Fatty Liver.

Celiac disease (CeD) is a chronic autoimmune disorder characterized by an intolerance to storage proteins of many grains. CeD is frequently associated with liver damage and steatosis. Bile acid (BA) signaling has been identified as an important mediator in gut-liver interaction and the pathogenesis of non-alcoholic fatty liver disease (NAFLD).

Anti-TNFα treatment in Crohn's disease: Impact on hepatic steatosis, gut-derived hormones and metabolic status.

Background And Aims: An association between Crohn's disease (CD) and hepatic steatosis has been reported. However, the underlying mechanisms of steatosis progression in CD are not clear. Among the most effective CD treatments are agents that inhibit Tumor-Necrosis-Factor (TNF) activity, yet it is unclear why anti-TNFα agents would affect steatosis in CD.

Gender and gut microbiota composition determine hepatic bile acid, metabolic and inflammatory response to a single fast-food meal in healthy adults.

Background & Aims: Regular consumption of fast-food (FF) as a form of typical Western style diet is associated with obesity and the metabolic syndrome, including its hepatic manifestation nonalcoholic fatty liver disease. Currently, it remains unclear how intermittent excess FF consumption may influence liver metabolism. The study aimed to characterize the effects of a single FF binge on hepatic steatosis, inflammation, bile acid (BA), glucose and lipid metabolism.

[The harmfulness of simple steatosis].

Over the past decades, non-alcoholic fatty liver disease (NAFLD) has emerged as the leading cause of chronic liver diseases in western societies. While the complications of NAFLD progression and particularly non-alcoholic steatohepatitis (NASH) have been widely recognized and statistically proven by emerging numbers of NASH related cirrhosis, transplantations and liver cancer, simple steatosis was widely recognized as a rather benign manifestation of NAFLD. However, emerging data suggests simple steatosis to be associated with increased mortality, related to hepatic- and extrahepatic manifestations of multiple metabolic and inflammatory complications of the disease.

Acute myeloid leukemia with central diabetes insipidus.

While acute myeloid leukemia (AML) is the most common type of acute leukemia in adulthood, the constellation of AML associated with central diabetes insipidus (CDI) is rare and typically occurs in patients with chromosome 3 or 7 abnormalities. This subgroup of AML is associated with a poor clinical outcome. In this report, we present a young woman with AML and concurrent CDI in the presence of inversion(3)(q21q26).

RNA-Seq transcriptome analysis to identify genes involved in metabolism-based diclofop resistance in Lolium rigidum.

Weed control failures due to herbicide resistance are an increasing and worldwide problem that significantly affect crop yields. Metabolism-based herbicide resistance (referred to as metabolic resistance) in weeds is not well characterized at the genetic level. An RNA-Seq transcriptome analysis was used to find candidate genes that conferred metabolic resistance to the herbicide diclofop in a diclofop-resistant population (R) of the major global weed Lolium rigidum.

Hypoglycemia due to paraneoplastic secretion of insulin-like growth factor-I in a patient with metastasizing large-cell carcinoma of the lung.

Context: Nonpancreatic tumors may cause recurrent hypoglycemia known as nonislet cell tumor hypoglycemia. It is due to overproduction and secretion by the tumor of incompletely processed IGF-II, termed big IGF-II. We recently identified a patient with recurrent hypoglycemia and low insulin, but without elevated big IGF-II.

Hepatic overexpression of murine Abcb11 increases hepatobiliary lipid secretion and reduces hepatic steatosis.

Abcb11 encodes for the liver bile salt export pump, which is rate-limiting for hepatobiliary bile salt secretion. We employed transthyretin-Abcb11 and BAC-Abcb11 transgenes to develop mice overexpressing the bile salt export pump in the liver. The mice manifest increases in bile flow and biliary secretion of bile salts, phosphatidylcholine, and cholesterol.

[Molecular genetics of cholesterol cholelithiasis: identification of human and murine gallstone genes].

Cholesterol cholelithiasis is one of the most common gastroenterological diseases in Western countries. It is a polygenic disease resulting from disturbed biliary cholesterol homeostasis. Association studies identified six human gallstone candidate genes.

Interaction of serotonin 5-hydroxytryptamine type 2C receptors with PDZ10 of the multi-PDZ domain protein MUPP1.

By using the yeast two-hybrid system, we previously isolated a cDNA clone encoding a novel member of the multivalent PDZ protein family called MUPP1 containing 13 PDZ domains. Here we report that the C terminus of the 5-hydroxytryptamine type 2C (5-HT(2C)) receptor selectively interacts with the 10th PDZ domain of MUPP1. Mutations in the extreme C-terminal SSV sequence of the 5-HT(2C) receptor confirmed that the SXV motif is critical for the interaction.

Cloning and characterization of MUPP1, a novel PDZ domain protein.

Using the yeast two-hybrid system we isolated a cDNA clone encoding a novel protein interacting with the C-terminal domain of the 5-HT2C receptor. The protein, named MUPP1 (multi-PDZ-domain protein), contains thirteen PDZ domains and no obvious catalytic domain; it is related to hINADL and a putative C. elegans polypeptide referred to as C52A11.

Correlation of germ-line mutations and two-hit inactivation of the WT1 gene with Wilms tumors of stromal-predominant histology.

The WT1 gene, located on chromosome 11p13, is mutated in a low number of Wilms tumors (WTs). Germ-line mutations in the WT1 gene are found in patients with bilateral WT and/or associated genital tract malformations (GU). We have identified 19 hemizygous WT1 gene mutations/deletions in 64 patient samples.

[Patulin in foods of vegetable origin. 2. Several kinds of fruit and vegetables and fruit and vegetable products (author's transl)].

Patulin was found in fruit with spontaneous brown rot (bananas, pineapples, grapes, peaches, apricots) as well as in moldy compots and in sallow-thorn juice. Fruit, vegetables and fruit and vegetable product were artificially infected with Penicillium expansum, P. urticae and Byssochlamys nivea; patulin was subsequently found in peaches, apricots, greengages, bananas, strawberries, honeydew melons, tomatoes, red and green paprika, cucumbers and carrots; in several kinds of compot, in tomato juice and tomato pulp --but not in ketchup.
