KML001 is sodium metaarsenite, and has shown cytotoxic activity in human tumor cell lines. The anti-cancer mechanism of KML001 involves cancer cell destruction due to DNA damage at the telomeres of cancer cell chromosomes. In this study, we assessed the vascular disrupting properties of KML001 and investigated whether KML001 as VDA is able to increase anti-tumor activity in irinotecan combined ...
We examined the hypothesis that a failure of the immune system to eradicate tumors is due to the immunosuppressive environment created by the growing tumor, which is influenced by the site of tumor growth. We demonstrated that T cell responses to a bystander Ag in mice were suppressed by a growing CT26 tumor. T cells purified from the growing tumor expressed mRNA for IL-10, TGF-beta, and Foxp3....
PURPOSE Radiofrequency ablation (RFA) is a common treatment modality for surgically unresectable tumors. However, there is a high rate of both local and systemic recurrence. EXPERIMENTAL DESIGN In this preclinical study, we sought to enhance the antitumor effect of RFA by combining it with huKS-IL2 immunocytokine [tumor-specific monoclonal antibody fused to interleukin-2 (IL2)] in mice bearin...
PURPOSE CXC chemokine ligand 10 (CXCL10) is a potent inhibitor of angiogenesis. We wonder whether the combination of CXCL10 with cisplatin would improve the therapeutic antitumor efficacy. EXPERIMENT DESIGN We evaluated the antitumor activity of the combination therapy in the immunocompetent C57BL/6 and BALB/c mice bearing LL/2 Lewis lung cancer and CT26 colon adenocarcinoma, respectively. Mi...
Seven different tumor cell lines (human melanoma SK MEL 28; hamster melanoma HM29; murine melanomas B16F10 and amelanotic melanoma B16a; human colon carcinoma 11("IX:murine colon carcinoma CT26; and murine Lewis lung carcinoma) were treated with thrombin at 0.5-1 unit/ml and examined for their ability to bind to adherent platelets; HM29 was studied for its ability to bind to fibronectin and von...
Colon cancer is characterized by its fast progression and poor prognosis, and novel agents of treating colon cancer are urgently needed. WZ35, a synthetic curcumin derivative, has been reported to exhibit promising antitumor activity. Here, we investigated the in vitro and in vivo activities of WZ35 and explored the underlying mechanisms in colon cancer cell lines. WZ35 treatment significantly ...
background: bacterial dna has immunostimulatory effects on different types of immune cells such as dendritic cells (dcs). application of dcs as a cellular adjuvant represents a promising approach in the immunotherapy of infectious disease and cancers. objectives: to investigate the effect of tumor antigen pulsed dcs in the presence of cpg-1826 in treatment of a murine model of cancer. methods: ...
Direct intratumor injection of a disabled infectious single cycle HSV-2 virus encoding the murine GM-CSF gene (DISC/mGM-CSF) into established murine colon carcinoma CT26 tumors induced a significant delay in tumor growth and complete tumor regression in up to 70% of animals. Pre-existing immunity to HSV did not reduce the therapeutic efficacy of DISC/mGM-CSF, and, when administered in combinati...
This study investigates the effect of PD1 blockade on therapeutic efficacy novel doxorubicin-loaded temperature-sensitive liposomes. Herein, we report photothermally-activated, low magnetoliposomes (mLTSL) for efficient drug delivery and magnetic resonance imaging (MRI). The mLTSL were prepared by embedding small nitrodopamine palmitate (NDPM)-coated iron oxide nanoparticles (IO NPs) in lipid b...
Boron neutron capture therapy (BNCT) was performed at the University of Missouri Research Reactor in mice bearing CT26 colon carcinoma flank tumors and the results were compared with previously performed studies with mice bearing EMT6 breast cancer flank tumors. Mice were implanted with CT26 tumors subcutaneously in the caudal flank and were given two separate tail vein injections of unilamella...
