Description
Most of the NPC patients suffer from local recurrences and distant metastases within 1.5 years after radiotherapy due to radioresistance. Distinct patterns of gene expression and signatures were found in NPC, and have been used to associate them with cell proliferation, apoptosis, invasion and metastasis, but few gene expression profiling studies have been focused on the tumor radioresistance.We used gene expression microarray analyses to identify the difference of mRNA in radioresistant NPC CNE2-IR cells and radiosensitive CNE2 cells.
