A novel recombinant exendin-4 human serum albumin fusion protein (rEx-4/HSA) expressed in Pichia pastoris was prepared and characterized. Ex-4 is a 39-amino acid peptide isolated from the salivary gland of the lizard Heloderma suspectum and is thought to be a novel therapeutic agent for type 2 diabetes. But to gain a continued effect, the peptide has to be(More)
BACKGROUND Due to the high morbidity and mortality of fulminant hepatitis, early diagnosis followed by early effective treatment is the key for prognosis improvement. So far, little is known about the gene expression changes in the early stage of this serious illness. Identification of the genes related to the very early stage of fulminant hepatitis(More)
AIM To evaluate the inhibitory effects of DNAzymes on the expressions of hepatitis B virus (HBV) s (HBsAg) and e (HBeAg) in 2.2.15 cells, and to explore the potential therapeutic effects of DNAzymes on replication of HBV genome. METHODS DNAzymes DrzBS and DrzBC specific to HBV (ayw subtype) s gene ORF A157UG and e gene ORF A1816UG, were designed and(More)
OBJECTIVE A novel multiplex real-time RT-PCR kit was developed to detect EV71, CoxA16 and other human enteroviruses simultaneously with an internal amplification control to avoids false negatives, which used for hand, foot and mouth disease in the clinical diagnosis and epidemiological surveillance. METHODS Design specific primers and probes of EV71,(More)
AIM To synthesize antisense oligonucleotides (ASODNs) of midkine (MK), package the ASODNs with nanoparticles, and to inhibit hepatocellular carcinoma (HCC) growth using these nanoparticles. METHODS HepG2 cell proliferation was analyzed in vitro using the 3-(4,5-dimethythiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2Htetrazolium, inner salt(More)
Autophagy refers to a lysosomal degradative pathway or a process of self-cannibalization. This pathway maintains nutrients levels for vital cellular functions during periods of starvation and it provides cells with survival advantages under various stress situations. However, the mechanisms responsible for the induction and regulation of autophagy are(More)
A long-lasting recombinant human serum albumin-interferon-alpha2b fusion protein (rHSA/IFNalpha2b) was prepared and its structure and biological activities were studied. rHSA/IFNalpha2b was expressed in methylotrophic yeast Pichia pastoris with HSA's natural signal peptide and purified by dye affinity chromatography, hydrophobic interaction chromatography,(More)
OBJECTIVE To investigate the association of genetic polymorphisms in glutathione S-transferases(GST) M1 with hepatitis beta-related hepatocellular carcinoma (HCC). METHODS Genomic DNA was isolated from peripheral blood of HBsAg carriers, including 91 cases of HCC, 58 liver cirrhosis(LC), 63 chronic hepatitis B(CHB), and 134 normal controls. GSTM1(More)
Dysregulation of the antiapoptotic protein cellular FLICE-like inhibitory protein (c-FLIP) has been proven to be associated with tumorigenesis and progress of most human cancers. However, its aberrant expression is poorly elucidated. MicroRNAs (miRNAs) are small non-coding RNAs that are involved in tumorigenesis through negatively regulating gene(More)
Sialic acid-binding immunoglobulin-like lectin-8 (Siglec-8) promotes the apoptosis of eosinophils and inhibits FcvarepsilonRI-dependent mediator release from mast cells. We investigated the genetic association between sequence variants in Siglec-8 and diagnosis of asthma, total levels of serum IgE (tIgE), and diagnosis of eosinophilic esophagitis (EE) in(More)
