Several studies have reported that activated receptor tyrosine kinases (RTKs) are highly expressed in colon cancer and may promote tumor growth and survival. However, there is little information available as to the function and signaling of RTKs in colon cancers. In the present study, we performed protein array technology to determine the expression status of various RTKs that are activated in ...

Newly diagnosed colon or rectal cancer should be staged using the TNM (tumor, node and distant metastasis) nomenclature to determine prognostic factors. Based on this staging, it is possible to select patients in need of adjuvant therapy following surgery. In patients with stage III colon cancer, adjuvant chemotherapy with fluorouracil and levamisole has been shown to produce a 40 percent reduc...

Despite advances in colon cancer treatments, resistance and recurrence remain a significant challenge in treating patients. Novel therapeutic strategies are in urgent need to overcome resistance and improve patient outcomes. MicroRNA based therapeutics have potential to help combat resistance. In this study, we have shown that low miR-15a expression correlates with poor patient prognosis. We ha...

Abstract Background Colorectal cancer is considered a potential causative agent of morbidity and death, making it particularly dangerous malignancy. The current study aims to assess the efficacy ferulic acid (FA) attenuate harmful side effect 5-fluorouracil (5FU) in colon tissues induced by 1,2-dimethylhydrazine (DMH). Results Regarding male Wistar-albino rats ( Rattus norvegicus ), combined FA...

Colon cancer is a leading cause of cancer-related death in developed countries. Although 5-fluorouracil (5FU) has traditionally been studied for its potential to induce apoptosis, its clinical use had been greatly limited as a result of the development of drug resistance in patients. Besides the medicines that could induce apoptosis in cancer cells, several other alternative treatments, which h...

Guan Chang Fu Fang (GCFF) is a natural compound, which is extracted from three medicinal plants, Agrimonia pilosa Ledeb., Patrinia scabiosaefolia and Solanum nigrum L. GCFF has demonstrated clinical efficacy in the treatment of colon cancer. At present, 5-fluorouracil (5-FU) is the primary active chemotherapeutic agent used for treating colon cancer. Using median-effect and apoptosis analyses, ...

BACKGROUND 5-Fluorouracil (5-FU) is the most commonly used drug in colon cancer therapy. However, despite impressive clinical responses initially, development of drug resistance to 5-Fu in human tumor cells is the primary cause of failure of chemotherapy. In this study, we established a 5-Fu-resistant human colon cancer cell line for comparative chemosensitivity studies. MATERIALS AND METHODS...

This study investigated the effect of miR-101 on proliferation, migration, invasion, and chemotherapy sensitivity in colon cancer cell lines HT-29 and RKO. MicroRNAs are a class of small noncoding RNA molecules, which play important roles in diverse biological processes of human cancers, such as carcinogenesis, development, differentiation, and apoptosis. The expression of miR-101 in colon canc...

It is known that in colon cancer patients, folinic acid (FA) given intravenously (i.v.) with 5-fluorouracil (5-FU) enhances the cytotoxic effects of chemotherapy. Adverse events regarding administration of FA have rarely been reported in the medical literature. A review of the existing data revealed just one case report of a colon cancer patient, who developed allergic reaction secondary to FA ...

Bevacizumab is a monoclonal antibody that targets vascular endothelial growth factor (VEGF), and it has shown promise as a clinical agent against metastatic colorectal cancer, and particularly in combination with chemotherapy. Bowel perforation is a known risk that's associated with bevacizumab use, but the etiology is unknown. Here we report on two cases of metastatic colorectal cancer in whic...
