GO and KEGG pathway analysis of differentially expressed cochlear sEV proteins from P3, P7, P14, and P21 mice. Differentially expressed cochlear sEV proteins were identified by GO analysis as part of biological processes (a), molecular components (b), and cell membranes (c). d KEGG pathway analysis showing the significantly enriched pathways of differentially expressed cochlear sEV proteins in the four age groups. The size of the bubble shows the amount of protein, and the intensity of the color indicates the number of genes targeted by the protein in a and d. e The STRING network analysis for cochlear sEV proteins
