Abstract:
Pyroptosis is a lytic and inflammatory form of gasdermin protein-mediated programmed cell death that is typically initiated by inflammasomes. The inflammasome response is an effective mechanism for eradicating germs and cancer cells in the event of cellular injury. The gasdermin family is responsible for initiating pyroptosis, a process in which holes are made in the cell membrane to allow inflammatory chemicals to escape. Mounting evidence indicates that pyroptosis is critical for controlling the development of cancer. In this review, we provide a general overview of pyroptosis, examine the relationship between the primary elements of pyroptosis and tumors, and stress the necessity of pyroptosis-targeted therapy in tumors. Furthermore, we explore its dual nature as a double-edged sword capable of both inhibiting and facilitating the growth of cancer, depending on the specific conditions. Ultimately, pyroptosis is a phenomenon that has both positive and negative effects on tumors. Using this dual impact in a reasonable manner may facilitate investigation into the initiation and progression of tumors and offer insights for the development of novel treatments centered on pyroptosis.
Insights
Pyroptosis, a programmed cell death process, is crucial in cancer development. Understanding its dual role in inhibiting or promoting tumors is key for developing new pyroptosis-targeted cancer therapies.
Area of Science:
- Immunology
- Cell Biology
- Oncology
Background:
- Pyroptosis is a lytic, inflammatory programmed cell death mediated by gasdermin proteins, typically initiated by inflammasomes.
- The inflammasome pathway is vital for eliminating pathogens and cancerous cells during cellular injury.
- Gasdermin proteins orchestrate pyroptosis by forming pores in the cell membrane, releasing inflammatory mediators.
Purpose of the Study:
- To provide an overview of pyroptosis and its role in cancer.
- To examine the relationship between pyroptosis and tumor development.
- To highlight the potential of pyroptosis-targeted therapies for cancer treatment.
Main Methods:
- This review synthesizes existing research on pyroptosis and its implications in oncology.
- It analyzes the molecular mechanisms underlying pyroptosis initiation and execution.
- The study explores the dual role of pyroptosis in cancer progression and inhibition.
Main Results:
- Pyroptosis plays a critical role in controlling cancer development.
- The gasdermin-mediated cell death process exhibits a dual nature, potentially inhibiting or promoting tumor growth.
- Specific cellular conditions dictate whether pyroptosis acts as an anti-cancer or pro-cancer mechanism.
Conclusions:
- Pyroptosis has a complex, dual impact on tumor initiation and progression.
- Targeting pyroptosis offers a promising avenue for novel cancer therapeutics.
- Further research into the nuanced effects of pyroptosis can guide the development of effective cancer treatments.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
