Summary

This summary is machine-generated.

Metastasis in colorectal cancer (CRC) is driven by distinct evolutionary processes and intratumoral heterogeneity. This study identifies FOXD1 as a novel marker for metastatic cancer stem cells, crucial for understanding CRC spread.

Area Of Science

  • Oncology
  • Genomics
  • Cancer Research

Background

  • Colorectal cancer (CRC) metastasis is a primary cause of patient mortality.
  • Understanding CRC metastasis mechanisms is vital for clinical and fundamental research.
  • CRC exhibits significant heterogeneity, impacting treatment outcomes.

Observation

  • Spatial transcriptomics (ST) revealed intratumoral heterogeneity (ITH) in primary and metastatic CRC tissues.
  • Metastatic tissues showed enrichment of cancer stem cells (CSCs).
  • Distinct evolutionary trajectories and dedifferentiation-differentiation processes were observed during metastasis.

Findings

  • FOXD1 was identified as a novel marker for metastatic CSCs.
  • FOXD1 predicts patient survival, particularly in metastatic CRC.
  • CD74-MIF interactions were dominant in metastatic tumor cells.

Implications

  • This research provides novel insights into the cellular mechanisms of CRC liver metastasis.
  • The findings lay the groundwork for developing new therapeutic strategies targeting CRC metastasis.
  • Identifying FOXD1 as a CSC marker opens avenues for targeted therapies.
