Summary
Activating Ras mutations drive ~30% of cancers, making Ras proteins key anticancer targets. New macromolecular inhibitors, including peptides and antibodies, are being developed to overcome challenges in targeting these difficult proteins.
Area of Science:
- Oncology
- Molecular Biology
- Drug Discovery
Background:
- Activating mutations in Ras proteins are implicated in approximately 30% of human cancers.
- Ras proteins are challenging drug targets due to their intracellular function and lack of binding pockets for small molecules.
Purpose of the Study:
- To provide an overview of developing macromolecular inhibitors targeting oncogenic Ras mutants.
- To explore various modalities for Ras-targeted anticancer drug discovery.
Main Methods:
- Review of emerging strategies for Ras protein inhibition.
- Analysis of macromolecular inhibitor classes including peptides, macrocycles, antibodies, non-immunoglobulin proteins, and nucleic acids.
Main Results:
- Significant research efforts are focused on developing novel therapeutic approaches against Ras.
- Macromolecular inhibitors offer promising alternatives to conventional small molecules for Ras targeting.
Conclusions:
- Targeting Ras proteins, particularly oncogenic mutants, remains a critical area in cancer therapy.
- Diverse macromolecular strategies are being investigated to overcome the inherent challenges of Ras drug discovery.

The Ras Gene
7.4K
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.

Small GTPases - Ras and Rho
5.5K
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.

Targeted Cancer Therapies
9.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

MAPK Signaling Cascades
8.8K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Abnormal Proliferation
5.3K
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...

Targets for Drug Action: Overview
10.8K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
