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/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)
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)
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)
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)
OBJECTIVE To investigate the effect of qianjin huanglian pill on kidney in monosodium L-glutamate (MSG)-treated insulin resistance (IR) mice. METHOD The ameliorative effect of qianjin huanglian pill on IR in MSG mice was evaluated in comparison with rosiglitazone (Ros). The fasting serum glucose, fasting serum insulin, insulin sensitivity index, urinary(More)
Refined-JQ (JQ-R) is a mixture of refined extracts from Coptis chinensis (Ranunculaceae), Astragalus membranaceus (Leguminosae) and Lonicera japonica (Caprifoliaceae), the three major herbs of JinQi-JiangTang tablet, a traditional Chinese medicine (TCM) formula. The mechanisms by which JQ-R regulates glucose metabolism and improves insulin sensitivity were(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)
The amphiphilic random copolymer of P(NVP-co-NHPSS) with photocleavable N-O sulfonate side groups has been prepared to investigate the light-triggered disruption of copolymer micelles. Methods of absorption and emission spectra, solution transmittance, dynamic light scattering (DLS), and transmission electron microscopy (TEM) were applied. It was found that(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)
