Scientists Discover Novel Pathway to Trigger Cancer Cell Death
TL;DR
Targeting RTN4 triggers pyroptosis in cancer cells, enhancing antitumor immune responses, offering a competitive advantage in cancer treatment.
By manipulating RTN4, the ER membrane undergoes remodeling, forming 'bubble' structures associated with pyroptosis, elucidating the mechanism behind this form of cell death.
Understanding RTN4's role in pyroptosis opens new possibilities for anticancer immunotherapy, improving cancer treatment and enhancing immune responses for a better tomorrow.
α-MG induces RTN4 degradation, shifting ER morphology and activating caspase-3/GSDME pathway, offering a novel approach in cancer research with potential therapeutic implications.

A groundbreaking study published in Protein & Cell reveals a promising approach to targeting cancer cells by manipulating the endoplasmic reticulum (ER) membrane dynamics. Researchers have discovered that targeting the protein reticulon-4 (RTN4) can trigger pyroptosis, an inflammatory form of programmed cell death that shows significant potential in cancer treatment.
The study demonstrates that by using a chemical probe called α-mangostin (α-MG), scientists can degrade RTN4, causing extensive remodeling of the ER membrane. This process shifts the ER morphology and activates the caspase-3/GSDME pathway, which drives pyroptosis in cancer cells.
In experimental models, RTN4 knockdown significantly inhibited tumor growth and enhanced immune responses. Notably, when combined with anti-PD-1 therapy, the results were particularly promising, suggesting a potential breakthrough in combination cancer treatments.
The research offers a novel perspective on cancer therapy by targeting ER dynamics. By identifying RTN4 as a druggable target, scientists have opened new possibilities for developing small molecule anticancer agents that can induce targeted cell death while simultaneously stimulating immune responses.
Dr. Ke-Wu Zeng, a corresponding author of the study, emphasized the transformative potential of this research, noting that targeting RTN4 could provide a powerful strategy for anticancer immunotherapy.
This discovery represents a significant step forward in understanding the molecular mechanisms of programmed cell death and could potentially lead to more effective, targeted cancer treatments in the future.
