Article Synopsis
  • Colorectal adenocarcinoma (COAD) is a significant cancer type, and this study investigates the role of wound healing-related genes in its progression to help improve diagnosis and treatment.
  • Seventy wound healing-associated genes were identified, leading to the discovery of four key genes (MMP2, FN1, NF1, PTK7) that show overexpression in COAD, which may serve as potential diagnostic markers.
  • These hub genes are linked to poor patient outcomes and tumor-promoting activities, with further implications for drug resistance and immune response in the context of COAD progression.
