Cancer metastasis involves accumulating genetic alterations. Understanding the link between these genetic changes (genotype) and cancer cell behavior (phenotype) is crucial for developing effective treatments.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Cancer progression is linked to accumulating genetic alterations.
  • Tumor suppressor genes and oncogenes accumulate during tumor progression, correlating with clinical aggressiveness.
  • Gene expression profiles differ between metastatic and non-metastatic cancer cells.

Purpose of the Study:

  • To understand the molecular mechanisms of cancer metastasis.
  • To identify genes whose alterations accumulate during cancer progression.
  • To elucidate the genotype-phenotype correlation in cancer metastasis.

Main Methods:

  • Molecular analyses of cancer cells at various progression stages.
  • Comparative analyses of gene expression profiles.

  • Identification of genes involved in metastasis using experimental models.

    • Main Results:

    • Genetic alterations in tumor suppressor genes and oncogenes correlate with cancer aggressiveness.
    • Differential gene expression is associated with metastatic potential.
    • Several genes have been identified with roles in inducing or suppressing metastasis.

    Conclusions:

    • Elucidating genotype-phenotype correlations is essential for understanding cancer metastasis.
    • Further research is needed to fully understand the complex process of metastasis.
    • This review summarizes 20 years of progress and discusses future directions in cancer metastasis research.
