TNC, COL18A1 and COL12A1 gene expression characterize fibroblasts known as ECM-CAF (Extracellular Matrix-Cancer Associated Fibroblasts) which participates in the aberrant remodeling of the extracellular matrix in breast cancer (Papanicolaou et al., 2022; Minini and Fouassier, 2023). Here, TNC is linked to cancer.
