Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...

Epidemiology and evidence have demonstrated that colon carcinoma is one of the most common gastrointestinal tumors in the clinic. Reports have suggested that Tunicamycin significantly inhibits aggressiveness of colon carcinoma cells by promotion of apoptosis. In the present study, the inhibitory effect of tunicamycin on colon cancer cells and the potential underlying molecular mechanism was inv...

The phenomenon of inhibition of tumor growth by tumor mass has been studied in many experimental animal systems and has been observed in several clinical scenarios. Not until the recent discovery of angiostatin, a circulating angiogenesis inhibitor generated in the pres ence of a murine Lewis lung tumor, has a satisfactory mechanism been proposed to explain this phenomenon. Thus far, no other a...

Introduction: Photodynamic therapy is a noninvasive therapeutic method for tumors with a maximum depth of 5 mm. On the other hand, most photosensitizers are also susceptible to ultrasound waves (the basis of sonodynamic therapy). Therefore, it is expected that a combination of the two therapeutic methods will increase effectiveness of photodynamic therapies for lower doses of sensitizer and cur...

BACKGROUND Colorectal cancer remains one of the leading causes of cancer death worldwide. Traditional Chinese Medicine (TCM) has played a positive role in colorectal cancer treatment. There is a great need to establish effective herbal formula for colorectal cancer treatment. Based on TCM principles and clinical practices, we have established an eight herbs composed formula for colorectal cance...

We investigated anti-angiogenic/vascular targeting therapy of established tumors in immunocompetent mice using an anti-human endoglin (EDG; CD105) monoclonal antibody (mAb) SN6j. SN6j weakly cross-reacted with murine endothelial cells but reacted neither with colon-26 murine colon carcinoma cells nor with 4T1 murine mammary carcinoma cells. Systemic administration of naked (unconjugated) SN6j s...

Potassium channels are essential for the regulation of cell proliferation. As reported, HERG protein is overexpressed in a wide range of human tumors, including colon carcinoma. The aim of this study was to investigate the effects of antibacterial agents sparfloxacin (SPFX), a blocker of HERG channel, on HERG K+ channel highly expressing colon cancer cells. Expression of HERG and apoptosis corr...

Abstract Objectives In our study, we aimed to (1) create a peritoneal metastasis (PM) model in nude mice, administer intraperitoneal chemotherapy using the infusion pump developed this model, and (2) compare efficacy of various drugs at different temperatures. Methods The was established mice CC531 colon carcinoma cell line. Models with were randomized into four groups seven animals each: Group...

The newly purified extracellular polysaccharides (exopolysaccharides) from Parachlorella kessleri (PCEPS) were evaluated on their antitumor and immunomodulatory effects in cell culture and mouse colon carcinoma peritoneal dissemination model. In two-dimensional cell culture, the PCEPS treatment inhibited cell growth of both murine and human colon carcinoma cells in a dose- and time-dependent ma...
