Figure 3. KEGG pathway analysis of the parental genes of differentially expressed circRNA candidates. (A) The most significantly enriched pathways: ovarian steroidogenesis, aldosterone synthesis and secretion, thyroid hormone signaling pathway, ubiquitin mediated proteolysis, Jak-STAT signaling pathway, and endocytosis. (B) The diagrammatic sketch of ovarian steroidogenesis pathway in which circLDLR (hsa_circ_0006877) is involved.
