Neonatal intrahepatic cholestasis is a heterogeneous disease of undetermined cause. There is an unreported subset of idiopathic neonatal intrahepatic cholestasis with an unusual histological combination of hepatic siderosis and macrovesicular steatosis. The patients were a 34-day-old female and a
OBJECTIVE
To investigate the plasma amino acid spectrum in infants more than 1-year-old with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) in order to identify potential diagnostic markers of NICCD.
METHODS
Infants less than 1 year of age who had been referred to our hospital
Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) is a kind of inborn errors of metabolism, with the main clinic manifestations of jaundice, hepatomegaly, and abnormal liver function indices. As a mitochondrial solute carrier protein, citrin plays important roles in aerobic
Experimental evidence has been provided that a histidine-loop within the nucleotide binding domain of ABC transporter is essential for efficient function of this class of transporter proteins. Here we report the first patient with a mutation of the putative histidine-loop of a human ABC transporter,
Serum concentrations of bile acids and tyrosine were determined in 14 premature infants with late metabolic acidosis and in 13 comparable controls without acidosis (protein intake 2 g/kg X d). At the same time the bile acids and the catalytic activity concentrations of lipase and trypsin were
Estradiol-17β-D-glucuronide (E17G), through the activation of different signaling proteins, induces acute endocytic internalization of canalicular transporters in rat, including multidrug resistance-associated protein 2 (Abcc2) and bile salt export pump (Abcb11), generating cholestasis. Insulin-like
CP-724,714, a potent and selective orally active HER2 tyrosine kinase inhibitor, was discontinued from clinical development due to unexpected hepatotoxicity in cancer patients. Based on the clinical manifestation of the toxicity, CP-724,714 likely exerted its hepatotoxicity via both hepatocellular
Endogenous opioids have nitric oxide (NO)-dependent cardiovascular actions. In the light of biological evidence of accumulation of endogenous opioids in cholestasis and also existence of NO-dependent bradycardia in cholestatic subjects, this study was carried out to evaluate the role of endogenous
Citrin deficiency is a disorder with two phenotypes: neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), and adult-onset type II citrullinaemia (CTLN2). NICCD presents in the first few weeks of life with prolonged cholestasis and metabolic abnormalities including aminoacidaemia
BACKGROUND
Primary biliary cirrhosis (PBC) is characterized by chronic progressive destruction of small intrahepatic bile ducts with portal inflammation and cholestasis, leading to fibrosis.
METHODS
We utilized a novel restriction analysis system to profile the expression of tyrosine kinases (TKs).
Hepcidin is downregulated during progressive cholestasis in biliary atresia, but the mechanism is unknown. To verify whether downregulation of hepcidin is specific to cholestasis irrespective of the patient's age, we first analyzed liver hepcidin mRNA and protein expression in adults with primary
Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) has high prevalence in East Asia, and has been reported in other parts of the world. NICCD is also the most common form of genetic cholestasis among East Asians. There has been reports of mortalities or liver OBJECTIVE
To investigate the clinical and laboratory features of neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) and to characterize the molecular basis and prognosis of this disease.
METHODS
Twenty-six patients with NICCD were collected because of idiopathic intrahepatic
The liver-specific bile salt export pump (BSEP) is crucial for bile acid-dependent bile flow at the apical membrane. BSEP, a member of the family of structurally related adenosine triphosphate (ATP)-binding cassette (ABC) proteins, is composed of 12 transmembrane segments (TMS) and two large
Five patients of cholestatic jaundice and multiple hyperaminoacidemias were uncovered during neonatal mass screening for homocystinuria. All five patients had increased plasma levels of methionine, citrulline, tyrosine, threonine, phenylalanine, lysine and arginine. Compared with those of
