Abstract:
The neoplastic tumour suppressors, Scribble, Dlg and Lgl, originally discovered in the vinegar fly Drosophila melanogaster, are currently being actively studied for their potential role in mammalian tumourigenesis. In Drosophila, these tumour suppressors function in a common genetic pathway to regulate apicobasal cell polarity and also play important roles in the control of cell proliferation, survival, differentiation and in cell migration/invasion. The precise mechanism by which Scribble, Dlg and Lgl function is not clear; however, they have been implicated in the regulation of signalling pathways, vesicle trafficking and in the Myosin II-actin cytoskeleton. We review the evidence for the involvement of Scribble, Dlg, and Lgl in cancer, and how the various functions ascribed to these tumour suppressors in Drosophila and mammalian systems may impact on the process of tumourigenesis.
Insights
Scribble, Dlg, and Lgl are tumor suppressors studied for their role in mammalian cancer. These proteins regulate cell polarity, proliferation, and migration, impacting tumor development.
Area of Science:
- Cell Biology
- Developmental Biology
- Oncology
Background:
- Scribble, Dlg, and Lgl are conserved tumor suppressors.
- These proteins regulate apicobasal cell polarity in Drosophila.
- Their roles in mammalian tumorigenesis are under investigation.
Purpose of the Study:
- To review the evidence for Scribble, Dlg, and Lgl involvement in cancer.
- To explore how their functions impact tumor development.
Main Methods:
- Literature review of studies on Scribble, Dlg, and Lgl.
- Analysis of their roles in Drosophila and mammalian systems.
Main Results:
- These tumor suppressors regulate cell polarity, proliferation, survival, and migration.
- They are implicated in signaling pathways, vesicle trafficking, and the cytoskeleton.
- Dysregulation of these proteins is linked to cancer.
Conclusions:
- Scribble, Dlg, and Lgl play critical roles in tumor suppression.
- Understanding their functions is key to developing cancer therapies.
