RAS mutations in human cancers: Roles in precision medicine

Area of Science:

• Molecular Biology
• Oncology
• Cell Signaling

Background:

• Ras proteins are central to cellular signaling networks governing growth, proliferation, survival, differentiation, adhesion, and motility.
• Ras genes were discovered nearly four decades ago as retroviral oncogenes, with human RAS gene mutations later linked to tumorigenesis.
• RAS is recognized as one of the most frequently deregulated oncogenes in human cancers.

Purpose of the Study:

• To review the historical discovery of RAS oncogenes.
• To summarize the role of frequent RAS mutations in human tumorigenesis and associated signaling pathways.
• To discuss the significance of RAS mutations in personalized medicine, targeted therapy, and as diagnostic/prognostic markers.

Main Methods:

• Literature review of pioneering works on RAS oncogenes.
• Analysis of genetic data linking RAS mutations to cancer.
• Summary of research on RAS-mutation-activated signaling networks.
• Review of studies on the application of RAS mutations in precision oncology.

Main Results:

• RAS oncogenes were discovered through retroviral studies.
• RAS gene mutations are prevalent in various human cancers, driving tumorigenesis.
• Mutated RAS activates specific signaling pathways crucial for cancer progression.
• RAS mutations serve as important determinants for molecular targeted therapies and as diagnostic/prognostic markers.

Conclusions:

• RAS mutations are critical drivers of human cancers.
• Understanding RAS signaling is vital for developing effective cancer treatments.
• RAS mutations hold significant promise for personalized medicine approaches in oncology.
