Using a Venn diagram of upregulated SL‐DEGs, we found subtype‐specific SL‐upregulated expression patterns, including BC activation‐related genes (Cd38, Ifi209 and Bank1) in BCs, and an aging‐related gene (Cdkn2b) in myeloid cells (Supporting Information Figure S2F). Here, CDKN2B is linked to breast cancer.
