Selenium may be beneficial in reducing the risk of cancer incidence and mortality in many cancer types such as liver, prostate, colorectal and lung. However, despite the extensive recent research on selenium and selenium-containing proteins, there are still open questions concerning their expression in certain human cancer types, including colorectal(More)
Numerous animal models have been developed to provide a deeper insight to tumor progression in the search for new therapeutic leverage. The closer the tumor model represents the real tumor disease, the better. The ideal model provides monitoring, tumor cell detection and quantification, and the physiological events involved in tumor progression and tumor(More)
We investigated the therapeutic efficiency of sulfonate-modified polyvinyl alcohol beads loaded with doxorubicin, irinotecan or mitoxantrone in vitro and in vivo in a model of experimental peritoneal carcinomatosis (PC). In vitro, cell proliferation was efficiently impaired by doxorubicin drug eluting bead (DEB) treatment while mitoxantrone DEBs were less(More)
During cancer therapy with DNA-damaging drug-agents, the development of secondary resistance to apoptosis can be observed. In the search for novel therapeutic approaches that can be used in these cases, we monitored chemotherapy-induced apoptosis resistance in a syngenic mouse tumor model. For this, syngenic murine colorectal carcinoma cells, which stably(More)
BACKGROUND AND AIMS Peritoneal carcinomatosis is a common cause of death in pancreatic cancer patients. In this metastatic stage of the disease, few patients show a sustained response to therapy. In the palliative situation, targeted and compartment restricted delivery of drugs offers the opportunity to focus drugs directly to the tumor site, which is a(More)
We have studied caspase-3 activation by combined DNA damage induction and EGFR kinase inhibition in order to identify potential EGFR-mediated survival signals conferring resistance to apoptosis in human colorectal tumor cells. The onset of apoptosis was microscopically imaged with a newly developed caspase-3 substrate sensor based on EGFP and tHcred1,(More)
Activation of vascular endothelial growth factor receptor 1 (VEGFR1/FLT1) and 2 (VEGFR2/KDR) involves receptor dimerization. Formation of VEGFR dimer has so far not been visualized in single intact cells. In the present study we describe different optical assays which can be used to observe dimerization of VEGFR1 and VEGFR2. Bimolecular fluorescence(More)
The combination of a fluoropyrimidine with receptor tyrosine kinase inhibitors in tumor treatment has been proposed to enhance their therapeutic efficiency. The synergism of such a combination in the treatment of colorectal carcinoma is equivocal although the epidermal growth factor receptor (EGFR) is frequently overexpressed in the tumors. We used human(More)
