A Unique peptides for the identified proteins. The x-axis values represent the number of unique peptides, and the y-axis values represent the number of proteins. B Heatmap of significant DEPs with 210 up-regulation and 200 down-regulation in At group compared to the healthy control tendons. Colors ranging from blue to yellow correspond to low to high expression levels. C Functional classification of AATR-related proteins within the categories of biological process, molecular function, and cellular component. D Significantly overrepresented GO terms identified by enrichment analysis. The x-axis values represent the percentage of the background, and the y-axis values represent the term of enriched GO terms. E Significantly overrepresented KEGG pathways identified by enrichment analysis. The x-axis values represent the percentage of the background, and the y-axis values represent the term of enriched KEGG pathways
