Abstract:
Rab GTPases are master regulators of intracellular trafficking and, in recent years, their role in the control of different aspects of tumour progression has emerged. In the present review, we show that Rab GTPases are disregulated in many cancers and have central roles in tumour cell migration, invasion, proliferation, communication with stromal cells and the development of drug resistance. As a consequence, Rab proteins may be novel potential candidates for the development of anticancer drugs and, in this context, the preliminary results obtained with an inhibitor of Rab function are also discussed.
Insights
Rab GTPases regulate cell movement and growth, and their malfunction is linked to cancer progression. Targeting these Rab proteins offers a promising new strategy for developing effective anticancer drugs.
Area of Science:
- Molecular Biology
- Cell Biology
- Oncology
Background:
- Rab GTPases are key regulators of intracellular vesicle trafficking.
- Emerging evidence highlights their significant involvement in various cancer hallmarks.
Purpose of the Study:
- To review the multifaceted roles of Rab GTPases in tumor progression.
- To explore the potential of Rab proteins as therapeutic targets in cancer treatment.
Main Methods:
- Literature review of studies on Rab GTPases in cancer.
- Analysis of Rab GTPase dysregulation across different tumor types.
- Discussion of preclinical data for Rab function inhibitors.
Main Results:
- Rab GTPases are frequently dysregulated in numerous cancers.
- These proteins play critical roles in tumor cell migration, invasion, proliferation, and stromal interactions.
- Rab GTPase inhibition shows preliminary promise as an anticancer strategy.
Conclusions:
- Rab GTPases are central to multiple aspects of tumor progression.
- Targeting Rab GTPases represents a novel and promising avenue for anticancer drug development.

Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
