Project description:To evaluate whether serum microRNAs can predict survival in nasopharyngeal carcinoma (NPC) patients, we analyzed the serum microRNA expression profiles in 8 NPC patients with shorter-survival time and 8 age- and gender-matched NPC patients with longer-survival time using microarray. We identified a four-microRNA signature can predict survival of NPC patients. 8 serum samples from nasopharyngeal carcinoma patients with shorter-survival time and 8 serum samples from nasopharyngeal carinoma patients with longer-survival time

Project description:As regulators in gene expression, microRNAs take part in most biological process including cell differentiation, apoptosis, cell cycle and epithelial-to-mesenchymal transition (EMT). In order to evaluate their roles during the growth factors-induced EMT process, microRNA expression profile changes induced by EGF or TGF-β treatment on nasopharyngeal carcinoma cell line HK-1 cells were analyzed by means of the Affymetrix genome wide microarray system. Human nasopharyngeal carcinoma cell line HK-1 was starved for 12 hours before stimulation with EGF (50 ng/mL) or TGF-β (10ng/ml) or Control (PBS) for 36 hours in RPMI-1640 medium (with 1% serum) to establish the in vitro model of EMT. Total RNA were extracted and detected by Affymetrix® GeneChip® miRNA Arrays.
