Figure 1. Overview of circRNA expression in human ovarian tissues. (A) The proportion of different types of circRNAs among all predicted circRNAs. (B) The proportion of newly discovered circRNAs among different types of circRNAs. (C) The distribution of newly discovered circRNAs in the human genome. (D) Differentially expressed (DE) circRNAs between young and aging human ovarian tissues. (E) The distribution of exons among all predicted circRNAs. (F) The mean length of circRNA isoforms among all predicted and newly discovered circRNAs. (G). The mean length of DE-circRNA isoforms.
