SRP311003 PRJNA715077 GSE169057 circRNA in cervical cancer tissue The sample library was built using ILUMIMA recommended kit, and the original data was sequenced using HiSeq 4000. The simple procedure is as follows: the sample RNA is reverse-transcribed into a cDNA, then a poly A is added at the 3' End, then the sample is connected to the sequencing connector of the kit, and then PCR amplification is performed. Finally, HiSeq 4000 was used to detect the fault. Overall design: Examination of different circRNA in normal cervical tissue and cervical cancer tissue. GSE169057
