CircUBAP2 is up-regulated in CC tissues and cell lines and highly expressed CircUBAP2 predicts poor outcomes. a, b The expression of circUBAP2 was detected in CC tissues and cell lines using qRT-PCR. c The role of circUBAP2 in the CC prognosis was analyzed by Kaplan–Meier method. d, e qRT-PCR analysis of circUBAP2 and UBP2 mRNA after treatment with RNase R in SiHa and HeLa cells was performed. f, g CircUBAP2 and UBP2 mRNA in either the cytoplasm or the nucleus was analyzed using qRT-PCR analysis in SiHa and HeLa cells. h, i The expression of circUBAP2 and UBP2 mRNA after transfected with sh-RNAs was measured by qRT-PCR. *P < 0.05
