Maltose-binding protein (MBP) is a component of the maltose transport system of Escherichia coli. Our previous study found that MBP combined with Bacillus Calmette-Guerin (BCG) increases the percentage of activated macrophages in the spleen and the pinocytic activity of peritoneal macrophages in vivo. However, the effect of MBP alone on macrophages remains(More)
In a previous study, we observed by global gene expression analysis that oncogene mucin1 (MUC1) silencing decreased transforming growth factor beta (TGF-β) signaling in the human hepatocellular carcinoma (HCC) cell line SMMC-7721. In this study, we report that MUC1 overexpression enhanced the levels of phosphorylated Smad3 linker region (p-Smad3L) (Ser-213)(More)
Maltose-binding protein (MBP), a component of the maltose transport system of Escherichia coli, has been commonly thought to have minimal bioactivity. Our previous studies demonstrated that MBP could significantly enhance Bacillus Calmette-Guerin (BCG)-induced T helper 1 (Th1) cell activation in mice. In the present study, we analyzed the effect of MBP on(More)
Our previous study demonstrated that maltose-binding protein (MBP) combined with BCG induced synergistic mouse Th1 activation in vivo. Here, to explore the mechanism of MBP combined with BCG on Th1 activation, mouse purified CD4+ T cells were stimulated with MBP and BCG in vitro. The results showed that MBP combined with BCG synergistically increased IFN-γ(More)
Mucin1 (MUC1), as an oncogene, plays a key role in the progression and tumorigenesis of many human adenocarcinomas. In this study, wound-healing, transwell migration and matrigel invasion assays showed that MUC1 promotes human hepatocellular carcinoma (HCC) cell migration and invasion by MUC1 gene silencing and overexpressing. Treatment with exogenous(More)
Mucin1 (MUC1) is a transmembrane glycoprotein that plays a key role as an oncogene in the tumorigenesis of many human adenocarcinomas. However, the role of MUC1 in human hepatocellular carcinoma (HCC) progression remains unclear. In the present study, we silenced MUC1 to investigate its effect on the human HCC cell line SMMC-7721 and found that knockdown of(More)
Mucin1 (MUC1) is a transmembrane glycoprotein that acts as an oncogene in human hepatic tumorigenesis. Hepatocellular carcinoma (HCC) cells often gain advantage by reducing the tumor-suppressive activity of transforming growth factor beta (TGF-β) together with stimulation of its oncogenic activity as in MUC1 expressing HCC cells; however, molecular(More)
Recently, gold nanoparticles (AuNPs) have shown promising biological applications due to their unique electronic and optical properties. However, the potential toxicity of AuNPs remains a major hurdle that impedes their use in clinical settings. Mesoporous silica is very suitable for the use as a coating material for AuNPs and might not only reduce the(More)
MBP (maltose-binding protein) is a component of Escherichia coli. Our previous study found that MBP directly induces the activation of Th1 (T helper type 1), but the molecular mechanism remains unclear. In the present study, CD4+T cells were purified from the spleens of normal mice using antibody-coated immunomagnetic beads by negative selection. CD4+T(More)
To explore whether TLR2/TLR4 could be involved in the maturation of dendritic cells and polarization of CD4+ T cells induced by dendritic cells stimulated with MBP and BCG, in vitro and in vivo experiments using TLR2-/- or TLR4-/- mice were employed. MBP and BCG elevated CD80, CD86 and MHC class II expressed on dendritic cells and increased IL-12 protein,(More)
