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. In present study, we investigated Bmi-1 expression and its prognostic significance in hepatocellular(More)
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)
Breast cancer is one kind of multi-gene related malignancy. Overexpression of some oncogenes such as HER-2 (c-erbB-2, Neu), bcl-2/bcl-xL, protein kinase A (PKA), and transferrin receptor gene (TfR gene), etc significantly affect the prognosis of breast cancer. It was shown that specific suppression of the overexpressed genes above resulted in the(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)
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)
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. In this study, we investigated IDO expression in hepatocellular carcinoma (HCC) cell lines and 138 primary HCC clinical(More)
AIM To study the role of mRNA secondary structure stability in antisense drug design and obtain better antisense candidates against neu/HER-2/erbB-2 mRNA than previous report. METHODS Program RNAstructure was utilized to simulate the secondary structures of HER-2 mRNA. Then 21 antisense phosphorothioate oligodeoxynucleotides (S-ODN) targeting different(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)
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)
BACKGROUND & OBJECTIVE Suppressor of cytokine signaling 1 (SOCS1) plays a critical role in antitumor immunity. Down-regulating SOCS1 in antigen-presenting dendritic cells (DCs) could enhance antigen-specific antitumor immunity. This study was to investigate the antigen-specific antitumor effect and mechanism of DCs with siRNA-mediated inhibition of SOCS1,(More)
