CircTRRAP was overexpressed in PCa. A Schematic illustration of the structure of circTRRAP. B CircTRRAP expression was measured in PCa tissues (n = 50) and corresponding normal tissues by qRT-PCR. C CircTRRAP abundance was detected in PC cell lines by qRT-PCR. D CircTRRAP abundance in the nuclear and cytoplasm fractions was assessed by qRT-PCR. E RNase R was administrated to digest the extracted RNA for analysis of the stability of circTRRAP. *P < 0.05
