Atrial fibrillation (AF) is a common disease with a poorly understood pathophysiological mechanism. Increasing evidence indicates that AF may be associated with immunologic inflammation responses, but it remains unclear whether activation of peripheral blood CD3(+) T-lymphocytes plays a role in the pathogenesis of AF. The aim of this study was to evaluate(More)
Heat shock protein 27 (HSP27) is an ubiquitiously expressed protein, which has been mediated in various biological functions. Here, we present a novel mechanism utilized by HSP27 in regulating IL-1beta induced NF-small ka, CyrillicB activation. Both over-expression and RNAi experiments indicate that HSP27 physically interacts with tumor necrosis factor(More)
Reactive oxygen species (ROS) exhibit a key role in the pathogenesis of inflammatory bowel disease (IBD). 3,3'-Diindolylmethane (DIM) can protect against oxidative stress in a breast cancer susceptibility gene 1 (BRCA1)-dependent manner. The aim of this study was to examine the therapeutic effects of DIM in experimental colitis and investigate the possible(More)
Transforming growth factor-β (TGFβ) is crucial for liver fibrogenesis and the blunting of TGFβ signalling in hepatic stellate cells (HSCs) or hepatocytes can effectively inhibit liver fibrosis. microRNAs (miRNAs) have emerged as key regulators in modulating TGFβ signalling and liver fibrogenesis. However, the regulation of TGFβ receptor I (TβRI) production(More)
Tumor-associated macrophages (TAMs) have been proven to be a driving force in the initiation, proliferation, metastasis and angiogenesis of various tumors. Specifically, alterations in the functions of TAMs exhibited inhibitory effects on tumor growth. However, there is currently no research being conducted on the targeting delivery of drugs into TAMs for(More)
Sustained activation of hepatic stellate cells (HSCs) leads to hepatic fibrosis, which is characterized by excessive collagen production, and for which there is no available drug clinically. Despite tremendous progress, the cellular activities underlying HSC activation, especially the driving force in the perpetuation stage, are only partially understood.(More)
Aberrant N-glycosylation caused by altered N-acetyl glucosaminyltransferase V (GnT-V) expression is known to regulate tumor invasion and metastasis by modulating multiple cytokine signaling pathways. However, the exact role of GnT-V in the development of liver fibrosis has not been clearly defined. Here, we induced mouse liver fibrosis by ip injections of(More)
BACKGROUND AND PURPOSE Hepatic fibrosis is a type of liver disease characterized by excessive collagen deposition produced by activated hepatic stellate cells (HSCs), and no appropriate drug treatment is available clinically. The microRNA, miR-21 exhibits an important role in the pathogenesis and progression of hepatic fibrosis. 3,3'-Diindolylmethane (DIM)(More)
Systemic blockade of TNF-α via monoclonal antibodies and soluble receptors has shown considerable effects against several typical autoimmune disorders, but remains unconvincing for the treatment of lupus. Based on our previous study, a CD169(+) macrophage-specific therapy using TNF-α antisense oligonucleotides (ASO) was tested for its efficacy in MRL/lpr(More)
Based on random censored data, the maximum likelihood estimation method of parameters of the weibull distribution is put forward. By the parameters estimation, the reliability analysis of the engineering data of rocket engine trials is given. The estimation values of shape parameters and reliability analysis show that the method is feasible.
