microRNA-seq in circCDYL probe and NC probe

CircRNA pull-down was performed as previously reported. Briefly, SK-BR-3 was fixed with 1% formaldehyde and lysed by co-IP buffer and the cluster was sonicated. CircCDYL-specific and NC biotinylated probes were added to mixture tobind circCDYL. Next, C1 streptavidin magnetic beads was added to pull down circCDYL and circCDYL-binding RNA. Finally, total RNA was extracted from the magnetic beads and followed by qRT-PCR detection of circCDYL and miR-92b-3p. Examination of 2 different treatment in Breast cancer cell.
