After obtaining a subpopulation of CD133+ OVCAR3 cells with£¿>£¿98% purity via cell sorting, miRNA microarray and real-time reverse transcription-polymerase chain reaction (RT-PCR) were performed to evaluate its miRNA profile.We found 37 differentially expressed miRNAs in the CD133+ spheroid-forming subpopulation of OVCAR3 cells, 34 of which were significantly up-regulated, including miR-205, miR-146a, miR-200a, miR-200b, and miR-3, and 3 of which were significantly down-regulated, including miR-1202 and miR-1181.Our results indicate that dysregulation of miRNA may play a role in the stem cell-like properties of ovarian CSCs. %K MicroRNA %K Cancer stem cell %K Ovarian cancer %K CD133 %K OVCAR3 %K Chemoresistance %U http://www.biomedcentral.com/1755-8794/5/18/abstract
