High expression of recombinant proteins in Escherichia coli (E. coli) often leads to protein aggregation. One popular approach to address this problem is the use of fusion tags (or partners) that improve the solubility of the proteins in question. However, such fusion tags are not effective for all proteins. In this study, we demonstrate that the(More)
We describe the clinical, biochemical and molecular genetic features of a Chinese family with sitosterolemia, mainly manifested by hematologic abnormalities. The clinical features of three patients were analyzed. Their plasma sterol levels were measured, and ABCG5 and ABCG8 genes sequenced to search for the causative mutation. The main clinical features of(More)
Both high fat diet (HFD) and valproic acid (VPA) interfere with mitochondrial β-oxidation of fatty acids, which subsequently triggers microvesicular fatty liver and hepatic dysfunction. UDP-glucuronosyltransferases, the major phase II drug metabolism enzymes, play a pivotal role in detoxifying various exogenous and endogenous compounds. This study aimed to(More)
Bile acids play a pivotal role in the pathological development of inflammatory bowel disease (IBD). However, the mechanism of bile acid dysregulation in IBD remains unanswered. Here we show that intestinal peroxisome proliferator-activated receptor a (PPARa)-UDP-glucuronosyltransferases (UGTs) signalling is an important determinant of bile acid homeostasis.(More)
Many clinical investigations have suggested that Helicobacter pylori (H. pylori) infection might be associated with immune thrombocytopenic purpura (ITP), but its role in the pathogenesis of ITP is unsettled. In this study, we cultured H. pylori, produced recombinant H. pylori urease (ure) B, and then prepared monoclonal antibody (MoAb) against ureB, 1F11,(More)
Maximization of the soluble protein expression in Escherichia coli (E. coli) via the fusion expression strategy is usually preferred for academic, industrial and pharmaceutical purposes. In this study, a set of distinct protein fusion partners were comparatively evaluated to promote the soluble expression of two target proteins including the bovine(More)
• Villin is one of the major actin filament bundling proteins in plants. The function of Arabidopsis VILLINs (AtVLNs) is still poorly understood in living cells. In this report, the biochemical activity and cellular function of AtVLN4 were examined. • The biochemical property of AtVLN4 was characterized by co-sedimentation assays, fluorescence microscopy(More)
Phytosterolemia is a rare autosomal recessive disease of plant sterol metabolism, the pathophysiological features of which are high plasma levels of plant sterols and xanthomatosis caused by mutations of ABCG5 and ABCG8 genes, and the combination of hemolysis and macrothrombocytopenia is an unusual clinical manifestation. All the patients of the 3 unrelated(More)
Disseminated intravascular coagulation (DIC) and thrombotic thrombocytopenic purpura (TTP) are different disease states, while ADAMTS13 deficiency could occur in sepsis-induced DIC. We report 2 patients who had septic DIC with features of idiopathic TTP characterized by low ADAMTS13 activity and positive ADAMTS13 inhibitor. They had a specific fulminant(More)
TP53-induced glycolysis and apoptosis regulator (TIGAR) inhibits glycolysis and increases the flow of pentose phosphate pathway (PPP), which generates NADPH and pentose. We hypothesized that TIGAR plays a neuroprotective role in brain ischemia as neurons do not rely on glycolysis but are vulnerable to oxidative stress. We found that TIGAR was highly(More)
