Abstract:
The Golgi complex is the central unit of the secretory pathway, modifying, processing and sorting proteins and lipids to their correct cellular localisation. Changes to proteins at the Golgi complex can have deleterious effects on the function of this organelle, impeding trafficking routes through it, potentially resulting in disease. It is emerging that several Rho GTPase proteins, namely Cdc42, RhoBTB3, RhoA and RhoD are at least in part localised to the Golgi complex, and a number of studies have shown that dysregulation of their levels or activity can be associated with cellular changes which ultimately drive cancer progression. In this mini-review we highlight some of the recent work that explores links between form and function of the Golgi complex, Rho GTPases and cancer.
Insights
The Golgi complex is vital for protein processing. Dysregulation of Rho GTPases at the Golgi is linked to cancer progression, highlighting a key area for future research.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Research
Background:
- The Golgi complex is central to the secretory pathway, essential for protein and lipid modification, processing, and sorting.
- Alterations in Golgi complex protein function can disrupt cellular trafficking and lead to disease.
- Several Rho GTPase proteins (Cdc42, RhoBTB3, RhoA, RhoD) are localized to the Golgi complex.
Purpose of the Study:
- To review recent research on the relationship between the Golgi complex, Rho GTPases, and cancer.
- To explore the links between the form and function of the Golgi complex and cancer progression.
- To highlight the role of Rho GTPase dysregulation in cellular changes driving cancer.
Main Methods:
- Literature review of recent studies.
- Analysis of research linking Golgi complex function, Rho GTPase activity, and cancer.
- Synthesis of findings on the cellular localization and functional impact of specific Rho GTPases.
Main Results:
- Rho GTPases are increasingly recognized as key players in Golgi complex function.
- Dysregulation of Rho GTPase levels or activity at the Golgi is associated with cellular changes that promote cancer.
- Specific Rho GTPases like Cdc42, RhoBTB3, RhoA, and RhoD have demonstrated roles in Golgi-associated processes.
Conclusions:

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...
