Profiling of circular RNA junctions from human PBMCS. (A) Cohorts information of PBMCs used in this study. We analyzed circular RNA junction from total RNA-seq data published previously. (B) Numbers of total circular RNAs, unique junctions, known junctions from previous publication and PMBCs isolated from young and old cohorts. (C) Common circular RNA junctions from young and old PBMCs. (D) Number of circular junctions originated from each chromosome. In the graph, the outer concentric circles represent data from young PBMCs and the inner concentric circles represent data from old PBMCs. (E) Percent of total junctions from each chromosome was calculated for the PBMCs from young cohort.
