Microarray expression profile and functional analysis of circular RNAs in cervical cancer

Five human cervical cancer cell lines (HeLa, CaSki, SiHa, C-33A, SW756) and one human normal cervical epithelial cell line HcerEpic were included in the study. Microarray based circRNA expression profiles were acquired using the Arraystar Human circRNA Array (8x15K, Arraystar). We identified circRNAs differentially expressed in human cervical cancer cell lines compared to human normal cervical epithelial HcerEpic cells (control). In the study presented here, the circRNA expression in human cervical cancer cell lines was compared to circRNA expression in human normal cervical epithelial cells (control).
