Summary
Targeting mutant Kirsten rat sarcoma viral oncogene homolog (KRAS) is key for cancer therapy. G protein-coupled receptor 31 (GPR31) mediates KRAS membrane association, offering a new therapeutic target for KRAS-dependent cancers.
Area of Science:
- Oncology
- Molecular Biology
- Drug Discovery
Background:
- Effective therapies targeting oncogenic Kirsten rat sarcoma viral oncogene homolog (RAS) are crucial for cancer treatment.
- Mutant Kirsten rat sarcoma viral oncogene homolog (KRAS) drives tumorigenesis by associating with the plasma membrane (PM).
Purpose of the Study:
- To identify novel therapeutic targets for KRAS-dependent cancers.
- To investigate the role of G protein-coupled receptor 31 (GPR31) in KRAS-driven tumorigenesis.
Main Methods:
- Investigated the association between GPR31 and KRAS.
- Assessed the impact of GPR31 on KRAS-dependent cancer cell proliferation, survival, and macropinocytosis.
Main Results:
- G protein-coupled receptor 31 (GPR31) was identified as a mediator of KRAS membrane association.
- GPR31 is essential for the proliferation, survival, and macropinocytosis of KRAS-dependent cancer cells.
Conclusions:
- GPR31 plays a critical role in sustaining KRAS-dependent cancers.
- GPR31 represents a promising druggable target for developing novel anti-RAS therapies.

02:38The 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.

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.

01:15G Protein-coupled Receptors
17.9K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

02:57Targeted 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.

02:23Abnormal 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...

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
