CircSETDB1 was overexpressed in SOC tissues and cells. A The schematic diagram demonstrated that circSETDB1 was generated from the exons 14–18 of SETDB1 through back-splicing. B and C CircSETDB1 expression was detected by qRT-PCR in SOC tissues (N = 73), normal fallopian tube tissues (N = 73) and IOSE-80, A2780 and SKOV3 cells. D The stability of circSETDB1 was determined by Actinomycin D treatment assay in A2780 and SKOV3 cells. *P < 0.05
