The inhibitor of growth (ING) family member 2 (ING2) is a newly discovered member of ING family that can regulate a wide range of cellular processes including cell growth arrest, apoptosis, and DNA repair. Researches have shown that ING2 can activate p53 and p53-mediated apoptotic pathway involved in the hepatocarcinogenesis. To investigate the role of ING2(More)
PURPOSE Recent studies have identified polycomb-group gene Bmi-1 as oncogene in the generation of mouse pre-cell lymphomas, and overexpression of Bmi-1 has been found in several human tumor with the disease progress and poor prognosis of the cancer patients. METHODS In present study, we investigated Bmi-1 expression and its prognostic significance in(More)
PURPOSE Immunoregulatory enzyme indoleamine 2,3-dioxygenase (IDO) plays an important role in immune tolerance. In some malignancies, the evidences were given to show that overexpression of IDO was related to poor prognosis of cancer patients. METHODS In this study, we investigated IDO expression in hepatocellular carcinoma (HCC) cell lines and 138 primary(More)
AIM To investigate the population pharmacokinetics of recombinant human tumor necrosis factor receptor-Fc fusion protein (rhTNFR-Fc) administered via subcutaneous (SC) injection in healthy Chinese volunteers and in Chinese patients with ankylosing spondylitis (AS). METHODS Thirty-two healthy volunteers were randomly assigned to receive a single SC(More)
AIM To study the pharmacokinetics and accumulation of an Escherichia coli expressed His-tag fused recombinant human endostatin (rh-endostatin) in Rhesus monkeys. METHODS Rh-endostatin was iv or sc injected in Rhesus monkeys, and the rh-endostatin concentration in serum samples was determined by an enzyme immunoassay (EIA) method. The serum drug(More)
Nesfatin-1 is an anorexigenic peptide involved in energy homeostasis. Recently, nesfatin-1 was reported to decrease blood glucose level and improve insulin sensitivity in high-fat diet-fed rats. However, little information is known about the influence of nesfatin-1 on lipid metabolism either in physiological or diabetic condition. This study undertook(More)
AIM Optimal design of antiviral short-interfering RNA (siRNA) targeting highly divergent hepatitis B virus (HBV) was validated by quantitative structure activity relationship (QSAR) analysis. METHODS The potency of 23 synthetic siRNAs targeting 23 sites throughout HBV pregenomic RNA were evaluated at 10 nmol/L by determining the inhibition on the(More)
The maximum absorption wavelengths of 31 azo dyes have been calculated by two comprehensive methods using the semiempirical quantum chemical method, PM3, and the weight decay based artificial neural network (WD-ANN) or the early stopping based artificial neural network (ES-ANN). The average absolute errors of WD-ANN and that of ES-ANN are 10.07 nm and 12.40(More)
BACKGROUND & OBJECTIVE Mucin-1 (MUC1), a tumor-associated antigen, is an optional molecular target for antitumor immunotherapy protocols. This study was to establish a subcutaneous human esophageal cancer transplantation model with MUC1 high expression in nude mice that closely resembles the biological features of human esophageal cancer, and provide a in(More)
AIM To optimize the antisense drug design by the combined method of phylogenetic analysis and secondary structure prediction and to get ideal candidates. METHODS The phylogenetic analysis and the secondary structure simulation were performed by computer. Oligodeoxynucleotides (ODN) were designed against the full-conserved blocks with low local reaction(More)
