Hypothesis
How does RND3-RHOA signaling affect melanoma cell invasion after BRAF inhibition?
Conclusion
The study shows that RND3 and RHOA signaling play critical roles in the movement of melanoma cells that survive BRAF inhibitor treatment.
Supporting Evidence
- BRAF inhibitors reduced cell survival but some cells remained viable and invasive.
- RND3 expression decreased with BRAF inhibition, while RHOA signaling increased.
- Restoring RND3 or knocking down RHOA reduced the migration of resistant melanoma cells.
Takeaway
Some melanoma cells can still move and invade even after treatment with BRAF inhibitors, and this is linked to changes in certain proteins.
Methodology
The study used WM793 melanoma cells and assessed the effects of BRAF inhibitors on cell morphology, signaling pathways, and invasion in 2D and 3D models.
Limitations
The study primarily focuses on a specific melanoma cell line and may not fully represent all melanoma types.
