CD133+CD24lo defines a 5-Fluorouracil-resistant colon cancer stem cell-like phenotype
The chemotherapeutic agent 5-Fluorouracil (5-FU) is the most commonly used drug for patients with advanced colon cancer. However, development of resistance to 5-FU is inevitable in almost all patients. The mechanism by which colon cancer develops 5-FU resistance is still unclear. One recently proposed theory is that cancer stem-like cells underlie colon cancer 5-FU resistance, but the phenotype...
متن کاملReduced Autophagy in 5-Fluorouracil Resistant Colon Cancer Cells
We investigated the role of autophagy in SNUC5/5-FUR, 5-fluorouracil (5-FU) resistant SNUC5 colon cancer cells. SNUC5/5- FUR cells exhibited low level of autophagy, as determined by light microscopy, confocal microscopy, and flow cytometry following acridine orange staining, and the decreased level of GFP-LC3 puncta. In addition, expression of critical autophagic proteins such as Atg5, Beclin-1...
متن کاملCD271 Defines a Stem Cell-Like Population in Hypopharyngeal Cancer
Cancer stem cells contribute to the malignant phenotypes of a variety of cancers, but markers to identify human hypopharyngeal cancer (HPC) stem cells remain poorly understood. Here, we report that the CD271(+) population sorted from xenotransplanted HPCs possesses an enhanced tumor-initiating capability in immunodeficient mice. Tumors generated from the CD271(+) cells contained both CD271(+) a...
متن کاملmethoxyamine enhances 5-fluorouracil-induced radiosensitization in colon cancer cell line ht29
objective: the purpose of this study was to observe the effects of methoxyamine (mx) on the cytotoxic effects and dna damage caused by 5-fluorouoracil (5-fu), in combination with gamma-rays in human colon cancer cell line. materials and methods: in this experimental study, ht29 cells were cultured as a monolayer and treated with different concentrations of 5-fu along with 1 mm mx for 24 h. afte...
متن کامل5-Fluorouracil upregulates the activity of Wnt signaling pathway in CD133-positive colon cancer stem-like cells.
BACKGROUND AND OBJECTIVE CD133-positive colon cancer stem like cells (CSLCs) are resistant to the conventional cytotoxic drug 5-fluorouracil (5-FU). Wnt signaling pathway plays important roles in colon cancer carcinogenesis and metastasis, and regulates the self-renewal capacity of CSLCs. In the present study, we explored the impact of 5-FU on Wnt signaling pathway of CD133-positive colon CSLCs...
