Characterization of circRNAs in Primary hBMECs

(A) Transcript lengths for the 41,504 circRNAs from the primary hBMECs in six samples. (B) Genomic origins of the circRNAs from the primary hBMECs in six samples. (C) For each sample, the identities of the circRNAs were confirmed by the CircBase database. (D) The proportion of circRNAs in CircBase matching our sequencing data. (E) The expression density distribution of the circRNAs in each sample. (F) The distributions of the differentially expressed circRNAs on all 23 chromosomes. Red is the number of downregulated circRNAs and blue is the number of upregulated circRNAs.
