Insights

RAS proteins regulate cell cycles and are crucial in cancer. This review covers RAS signaling pathways, targeted therapies, and how RAS mutations predict treatment response in cancers like colorectal and lung.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Signaling

Background:

  • RAS proteins are key regulators of the cell cycle.
  • The RAS signaling pathway influences cell survival and angiogenesis via downstream pathways like RAF/MEK/ERK and PI3K/AKT/mTOR.
  • Alterations in the RAS pathway are implicated in various cancers, leading to the development of targeted therapies.

Purpose of the Study:

  • To review the regulation of RAS proteins in cancer.
  • To detail the main RAS downstream signaling pathways.
  • To discuss therapeutic strategies targeting RAS and its effectors, including predictive value of RAS mutations for EGFR-targeted agents.

Main Methods:

  • Literature review of RAS protein regulation in cancer.
  • Analysis of RAS downstream signaling pathways.
  • Discussion of targeted therapeutic approaches and predictive biomarkers.

Main Results:

  • The RAS pathway's role in cell cycle, survival, and angiogenesis is multifaceted.
  • Numerous targeted agents acting on the RAS pathway components are in clinical use.
  • RAS mutations can predict patient response to specific therapies, particularly EGFR inhibitors.

Conclusions:

  • Targeting the RAS pathway offers significant therapeutic potential in oncology.
  • Understanding RAS signaling is critical for developing effective cancer treatments.
  • RAS mutation status is an important biomarker for guiding treatment decisions in certain cancers.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
