BACKGROUND/AIMS Estradiol (EST) reduces the risk of stroke and decreases the incidence and progression of the disease because of its neuroprotective roles in inhibiting cell death that occurs in response to a variety of neuronal stimuli such as inflammation and oxidative stress. In this study, we determined the role played by autophagy and Nrf2-ARE signal(More)
Glucagon like peptide-1 (GLP-1) receptor agonists such as exendin-4 have been widely used but their short half-life limits their therapeutic value. The recombinant protein, E2HSA, is a novel, long-acting GLP-1 receptor agonist generated by the fusion of exendin-4 with human serum albumin. In mouse pancreatic NIT-1 cells, E2HSA activated GLP-1 receptor with(More)
BACKGROUND AND PURPOSE Glucokinase (GK) balances blood glucose levels via regulation of glucose metabolism and insulin secretion. Peroxisome proliferator activated receptor-γ (PPARγ) regulates gene expression in glucose and lipid metabolism. In this study, we investigated the therapeutic effect of a novel compound, SHP289-03, which activates both GK and(More)
A versatile flow cytometric bead assay (FCBA) has been developed for the ultrasensitive detection of T4 PNK activity by integrating the advantages of the phosphorylation-induced hybridization chain reaction (HCR) for fluorescence signal amplification and flow cytometry for the robust, sensitive and rapid signal readout of the microbeads (MBs).
Accurate and rapid detection of protein kinase activities is of great significance because protein kinases play important regulatory roles in many vital biological processes. Herein, we wish to report a facile colorimetric protein kinase assay based on the phosphorylation-tuned crosslinking of gold nanoparticles (GNPs) by using protein kinase A (PKA) as a(More)
Vanadium compounds maintain euglycemic effects in diabetic rats long after drug withdrawal and bis(α-furancarboxylato)oxovanadium(IV) (BFOV) possesses potent antidiabetic effects in diabetic rats. Here, we investigated the treatment and posttreatment effects of BFOV in diabetic Kuo Kondo [1, 2] with Ay gene (KKAy) mice, and whether these effects were(More)
Glucagon like peptide-1 (GLP-1) plays a vital role in glucose homeostasis and sustaining β-cell function. Currently there are two major methods to enhance endogenous GLP-1 activity; inhibiting dipeptidyl peptidase-4 (DPP4) or activating G protein-coupled receptor 119 (GPR119). Here we describe and validate a novel dual-target compound, HBK001, which can(More)
B cell activation and excessive immunoglobulin (Ig) production were suggested as the key molecular events of chronic rhinosinusitis with nasal polyp (CRSwNP). However, whether T follicular cells (Tfh cells) were involved in this process has not been documented. In this study, 22 CRSwNP patients and 12 normal controls were enrolled, Bcl-6 (the key(More)
GW002 is a recombinant protein engineered by fusing the C-terminal region of human glucagon-like peptide-1 (GLP-1) to the N-terminal region of human serum albumin (HSA) with a peptide linker. This study aims to evaluate its anti-diabetic effects both in vitro and in vivo. The GLP-1 receptor-dependent luciferase reporter plasmid was transiently transfected(More)
Pioglitazone, a selective ligand of peroxisome proliferator-activated receptor gamma (PPARγ), is an insulin sensitizer drug that is being used in a number of insulin-resistant conditions, including non-alcoholic fatty liver disease (NAFLD). However, there is a discrepancy between preclinical and clinical data in the literature and the benefits of(More)
