JAK2 and aging: Based on protein–protein interaction enrichment analysis, these targets were demonstrated to have regulatory relationship with hallmark proteins, such as PIK3R1, STAT3, IL7R, and JAK2 (Figure 5B and Table S9), which have function in cancer, immune response, and intercellular transduction, bolstering the probability that other non‐miRNA sncRNAs also have functions in aging and aging‐related diseases.
