The huKS1/4-IL2 fusion protein, directed against the human epithelial cell adhesion molecule (huEpCAM) has been shown to induce a strong CD8+ T-cell-dependent, natural killer (NK) cell-independent, antitumor response in mice bearing the huEp-CAM-transfected CT26 colon cancer CT26-EpCAM. Here we investigate the effectiveness of huKS1/4-IL2 against CT26-Ep21.6, a subclone of CT26-EpCAM, expressin...
In vivo magnetic resonance imaging of mice liver tumors using a new gadolinium-based contrast agent.
We compared the enhancement effect between a newly synthesized tissue-specific contrast agent, [Gd-DOTA-FPβG], and a commercially available agent, [Gd(DOTA)](-), in a murine model of liver tumor using a clinical magnetic resonance imaging scanner. The colon cancer cell lines with and without β-glucuronidase (βG) expression were implanted into the liver of mice. Self-synthesized gadolinium-based...
Objectives Low penetration depth of light is the main defect of photodynamic therapy (PDT), which could be improved by sonodynamic therapy (SDT). In this study, a combination of PDT and SDT known as sonophotodynamic therapy (SPDT) was investigated using two reverse arrangements in CT26 tumor model. Materials and Methods The liposomal zinc phthalocyanine was synthesized and characterized. It w...
Several chemotherapies, including the anthracycline analog mitoxantrone, are known to induce an immunogenic cell death in tumor cells that can produce a protective anti-tumor immune response in mice. Although the antitumor immune response mediated by mitoxantrone tumor cell death has been well described, it is not fully understood what effect age has on these responses. Our objectives were to 1...
PURPOSE Photodynamic therapy (PDT), which is used clinically for the palliative treatment of cancer, induces local tumor cell death but has no effect on tumors in untreated sites. The purpose of this study was to determine if local PDT followed by intratumoral injection of naïve dendritic cells (IT-DC) induces systemic antitumor immunity that can inhibit the growth of untreated as well as PDT +...
Host mediated anti-tumor effect of oncolytic Newcastle disease virus after locoregional application.
Several strains of the Newcastle disease virus (NDV) have raised considerable interest in recent years for clinical application because of their oncolytic properties. In this study we characterized virological, immunological and anti-tumor properties of some NDV strains. The oncolytic strain MTH-68/H was the most potent interferon-alpha inducer and, after UV light inactivation, it was the only ...
Clostridium difficile toxin B (TcdB) is a key virulence factor of bacterium and induces intestinal inflammatory disease. Because of its potent cytotoxic and proinflammatory activities, we investigated the utility of TcdB in developing anti-tumor immunity. TcdB induced cell death in mouse colorectal cancer CT26 cells, and the intoxicated cells stimulated the activation of mouse bone marrow-deriv...
Replication-competent retrovirus (RCR) vectors are intrinsically incapable of infecting quiescent cells and have been shown to achieve highly efficient and tumor-restricted replicative spread and gene transfer in vivo after direct intratumoral injection in a variety of primary cancer models. However, i.v. delivery of RCR vectors expressing therapeutic genes has never previously been tested, par...
The use of complementary and alternative medicines-including a variety of herbal therapies-by patients undergoing cancer chemotherapy has been well documented. Despite such widespread use, however, the benefits and potential mechanisms of such herbal medicines remain largely anecdotal. In this study we examined the effects of a Chinese herbal formula, Bing De Ling, when administered as an adjun...
The formation of hepatic metastases in colorectal cancer is the main cause of patient death. Current therapies directed at hepatic metastasis of colorectal cancer have had minimal impact on outcome. Therefore, alternative treatment strategies for liver metastasis require development. The present study was performed to evaluate the application of cDNA of LK68 encoding apolipoprotein(a) kringles ...
