Insights

Rab GTPases are key regulators of vesicle trafficking. Their dysregulation drives cancer progression, offering potential therapeutic targets for tumor restraint.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Oncology

Background:

  • Rab GTPases are crucial for membrane transport and vesicle trafficking.
  • Their functions are essential for cellular processes including endosomal transport and autophagosome biogenesis.
  • Dysregulation of Rab proteins is linked to cancer development and progression.

Purpose of the Study:

  • To review recent advances in understanding the roles of Rab GTPases in tumor progression.
  • To highlight the context-dependent functions of Rab proteins in different cancers.
  • To emphasize the impact of dysregulated Rab-mediated membrane delivery on cancer cell biology.

Main Methods:

  • Literature review of recent advances in Rab GTPase research.
  • Analysis of the communication between Rab GTPases and their effectors in tumor progression.
  • Emphasis on the shift from normal cell behavior to malignancy due to disrupted vesicle trafficking.

Main Results:

  • Rab GTPases coordinate vesicle trafficking pathways and cargo delivery.
  • Impaired Rab protein function contributes to uncontrolled cell growth, invasion, and metastasis.
  • The same Rab protein can act as an oncoprotein or tumor suppressor depending on the cancer context.

Conclusions:

  • Rab GTPases play critical roles in cancer cell biology.
  • Dysregulation of Rab-mediated membrane trafficking contributes to malignancy.
  • Targeting aberrant vesicle trafficking systems presents a potential strategy for cancer therapy.

Vesicular Tubular Clusters01:45

Vesicular Tubular Clusters

After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.
With the help of motor proteins such...

Rab Cascades01:25

Rab Cascades

Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Intralumenal Vesicles and Multivesicular Bodies01:38

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
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...
