IHC staining showed that the lnc‐FSD2‐31:1 level in tumor cells inhibited levels of fibronectin, collagen 1, α‐SMA, and Ki67, and increased levels of ATG7, whereas ATG7‐depleted CAFs would reverse these trends (Figure 5G, Figure S5G‐K, Supporting Information). This evidence concerns the gene MKI67 and neoplasm.
