Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Ras genes are frequently identified oncogenes in human cancers.
  • Suppressing ras oncogenicity is a key area of cancer research.

Purpose of the Study:

  • To review and classify methods for suppressing ras oncogenicity.
  • To explore the potential of these suppression methods in treating ras-oncogene-induced tumors.

Main Methods:

  • Classification of suppression methods into genetical, biological, and pharmacological approaches.
  • Review of reagents that inhibit ras gene/protein expression or function.
  • Examination of strategies targeting collaborating genes or enhancing tumor suppressor genes.

Main Results:

  • Suppression methods target ras gene integration, transcription, translation, and post-translational modification.
  • Some reagents are effective against both experimental and natural human ras-transformed cells.
  • Inhibition of collaborating genes or enhancement of tumor suppressor genes also suppresses ras-transformation.

Conclusions:

  • Ras oncogene suppression offers novel approaches to studying malignant transformation.
  • These strategies hold potential for the treatment of human cancers driven by ras oncogenes.
