background: proliferation and expansion of cancer stem cells as spheroids were proved in previous studies. but, capability of primary tumor-derived stem cells to keep their unique properties in vitro is still disputed. so, the goal of this study was to isolate, expand and characterize of colon cancer-derived stem cells. material and methods: in the present work, colon cancer stem cells markers ...

background: determination of the impact of angiogenesis on tumor development and progression is essential. this study aimed to determine the serum levels of vascular endothelial growth factor (vegf) and interleukin 6 (il-6) in breast carcinoma, and to correlate them with tumor size, lymph node involvement, and cancer stage. methods: under aseptic precautions 5 ml of venous blood was collected f...

results a low adc value was associated with lymph node metastasis (p < 0.01) and with high ki-67 protein levels (p = 0.03). there were no significant differences in the adc values among the histological grade (p = 0.48), molecular subtype (p = 0.51), tumor size (p = 0.46), and p53 protein level (p = 0.62). conclusion the pre-operative use of the 3.0 tesla dwi could provide information about the...

Background: Increased levels of total and lipid-associated sialic acid (TSA and LASA) have been reported in the sera of patients with benign or malignant tumors and also could be regarded as newly important clinical criteria for the diagnosis of cancer. This study has investigated the differences of TSA and LASA contents between cancer patients and healthy individuals and evaluated their correl...

conclusions traf6 plays an important role in the onset of colon cancer; therefore, drugs targeting it may have great clinical significance in the treatment of this disease. results the positive expression rate of traf6 in tumor tissues was 66.7%, which was significantly higher than in normal paracancerous tissues (18.5%). the positive expression rate of traf6 was significantly correlated with d...

background: transcriptional silencing of tumor suppressor genes and tumor related genes like gstp1 by methylation of promotor region cpg island is believed to be an important mechanism in tumorigenesis. the gstp1 gene encodes the enzyme glutathione s-transferase pi which defends the cells against oxidative damage and electrophilic carcinogens. methods: to gain insight into the role of epigeneti...

breast cancer is the most common cancer in women worldwide. breast cancer in one third of all patients will go on to metastasis, which is the main cause of mortality in cancer cases. tumor cells detach from primary tumor and enter into the circulation as circulating tumor cells (ctcs) which can form metastatic lesions. in this study, the expression of ck-19 gene in blood samples of metastatic b...

Background: Recent evidence suggests that regular exercise training is effective in treating various aspects of cancer. Therefore, the purpose of this study was to determine the effect of 8 weeks of aerobic interval training on monocarboxylate transporter 1 (MCT1) protein and expression of p53 gene in tumor of colon cancer mice. Methods: The present study was conducted experimentally from May ...

A growing area of research is focused on cancer therapy, and new therapeutic approaches are welcomed. Mesenchymal stem cell (MSC)-based gene therapy is a promising strategy in oncology. Intrinsic tropism and migration to tumor microenvironment with off lights are attractive features of this type of cell carrier. In this way, suicide genes have also found a good platform for better performance a...
