PURPOSE It has been suggested that constitutive up-regulation of cyclooxygenase (COX)-2 is associated with resistance to apoptosis, increased angiogenesis, and increased tumor invasiveness in various cancers including colon cancer. There are many factors involved in the resistance to 5-fluorouracil (5-FU) in colon cancer. However, little is known about the role of COX-2 in acquired resistance t...
Cell viability studies of HT29 colon cancer cells treated with the CO-releasing compound [Mn(CO)(3)(tpm)]PF(6) revealed a significant photoinduced cytotoxicity comparable to that of established agent 5-fluorouracil (5-FU), while controls kept in the dark were unaffected at up to 100 microM.
The resistance of colon cancer to 5-fluorouracil (5-FU) is a critical issue, and the cause of this resistance cannot always be explained based on the known molecules. Heat shock protein 27 (HSP27) mRNA expression has recently been shown to be correlated with 5-FU resistance in 5-FU-resistant cell lines. In this study, we attempted to elucidate the functional mechanism of HSP27 in 5-FU resistanc...
BACKGROUND Folates, components of the B-complex vitamins, have numerous pharmacological effects. In oncology combining folates with 5-fluorouracil (5-FU) enhances the cytotoxic effects of chemotherapy in colon cancer patients. Folic acid has been rarely involved in adverse allergic reactions. To the best of our knowledge no anaphylactic reaction secondary to folinic acid (FA) administration has...
Fluoropyrimidines are the chemotherapy backbone in the treatment of adenocarcinoma of the colon. Adjuvant 5-fluorouracil (5-FU)/leucovorin (LV) has been shown to significantly increase recurrence-free survival compared to surgery alone for patients with stage III colon cancer. Furthermore, the addition of oxaliplatin to 5-FU/LV (FOLFOX) in the adjuvant setting has been shown to provide an impro...
Colon cancer is the third most common cancer and the third largest cause of cancer-related death. Fluorouracil (5-FU) is the front-line chemotherapeutic agent for colon cancer. However, its response rate is less than 60%, even in combination with other chemotherapeutic agents. The side effects of 5-FU also limit its application. Nanoparticles have been used to deliver 5-FU, to increase its effe...
The MEK5/ERK5 signaling pathway is emerging as an important contributor to colon cancer onset, progression and metastasis; however, its relevance to chemotherapy resistance remains unknown. Here, we evaluated the impact of the MEK5/ERK5 cascade in colon cancer cell sensitivity to 5-fluorouracil (5-FU). Increased ERK5 expression was correlated with poor overall survival in colon cancer patients....
