Abstract:
Rab35 is a small GTPase that is involved in many cellular processes, including membrane trafficking, cell polarity, lipid homeostasis, immunity, phagocytosis and cytokinesis. Recent studies showed that activating mutations confer Rab35 with oncogenic properties. Conversely, downregulation of Rab35 inverts apico-basal cell polarity and promotes cell migration. Here we review Rab35's known functions in membrane trafficking and signaling, cell division and cell migration in cancer cells and discuss the importance of Rab35-dependent membrane trafficking in cancer progression.
Insights
Rab35, a small GTPase, plays a dual role in cell biology. Activating mutations drive cancer, while its downregulation disrupts cell polarity and promotes migration, impacting cancer progression.
Area of Science:
- Cell Biology
- Molecular Biology
- Cancer Research
Background:
- Rab35 is a small GTPase regulating critical cellular functions like membrane trafficking and cell polarity.
- Emerging evidence highlights Rab35's oncogenic potential through activating mutations.
- Rab35 downregulation is linked to inverted cell polarity and enhanced cell migration.
Purpose of the Study:
- To review the known functions of Rab35 in cellular processes.
- To discuss Rab35's role in membrane trafficking and signaling.
- To explore the significance of Rab35 in cancer cell division and migration.
Main Methods:
- Literature review of recent studies on Rab35.
- Analysis of Rab35's involvement in membrane trafficking pathways.
- Examination of Rab35's impact on cell polarity and migration.
Main Results:
- Rab35 is implicated in diverse cellular activities including phagocytosis and cytokinesis.
- Activating Rab35 mutations are associated with oncogenic properties.
- Loss of Rab35 function inverts apico-basal polarity and promotes cell migration.
Conclusions:
- Rab35 is a key regulator of membrane trafficking with significant implications in cancer.
- Understanding Rab35-dependent pathways is crucial for deciphering cancer progression mechanisms.
- Targeting Rab35 may offer therapeutic strategies for cancer treatment.
