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)
• 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)
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)-UDPglucuronosyltransferases (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)
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)
In previous studies, we showed that TP53-induced glycolysis and apoptosis regulator (TIGAR) protects neurons against ischemic brain injury. In the present study, we investigated the developmental changes of TIGAR level in mouse brain and the correlation of TIGAR expression with the vulnerability of neurons to ischemic injury. We found that the TIGAR level(More)
We conducted this randomized trial to investigate the efficacy and safety of rapamycin treatment in adults with chronic immune thrombocytopenia (ITP). Eighty-eight patients were separated into the control (cyclosporine A plus prednisone) and experimental (rapamycin plus prednisone) groups. The CD4⁺CD25⁺CD127(low) regulatory T (Treg) cells level, Foxp3 mRNA(More)
Pregnane X receptor (PXR) activation exhibits anti-inflammatory effects via repressing nuclear factor-κB (NF-κB); however, its overactivation may disrupt homeostasis of various enzymes and transporters. Here we found that ginsenosides restore PXR/NF-κB signaling in inflamed conditions without disrupting PXR function in normal conditions. The effects and(More)
Idiopathic thrombocytopenic purpura (ITP) is an acquired autoimmune disorder. Both impaired platelet production and T cell-mediated effects play a role in ITP thrombocytopenia. A Th1 polarization of the immune response, up-regulation of Th17 cells and decreased number of Treg cells have been demonstrated in ITP patients. High-dose dexamethasone was(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)
