Abstract:
Pyroptosis is a programmed cell death characterized by the rupture of the plasma membranes and release of cellular content leading to inflammatory reaction. Four cellular mechanisms inducing pyroptosis have been reported thus far, including the (i) caspase 1-mediated canonical, (ii) caspase 4/5/11-mediated non-canonical, (iii) caspase 3/8-mediated and (iv) caspase-independent pathways. Although discovered as a defense mechanism protecting cells from infections of intracellular pathogens, pyroptosis plays roles in tumor initiation, progression and metastasis of tumors, as well as in treatment response to antitumor drugs and, consequently, patient outcome. Pyroptosis induction following antitumor therapies has been reported in several tumor types, including lung, colorectal and gastric cancer, hepatocellular carcinoma and melanoma. This review provides an overview of the cellular pathways of pyroptosis and discusses the therapeutic potential of pyroptosis induction in cancer, particularly in melanoma.
Insights
Pyroptosis, a programmed cell death, involves membrane rupture and inflammation. This review explores its pathways and therapeutic potential in cancer, especially melanoma.
Area of Science:
- Cell Biology
- Immunology
- Oncology
Background:
- Pyroptosis is a programmed cell death mechanism causing membrane rupture and inflammation.
- It involves four pathways: canonical, non-canonical, caspase-mediated, and caspase-independent.
- Initially identified as an anti-pathogen defense, pyroptosis also influences tumor development and treatment response.
Purpose of the Study:
- To review the cellular pathways of pyroptosis.
- To discuss the therapeutic potential of inducing pyroptosis in cancer treatment.
- To specifically examine pyroptosis in melanoma.
Main Methods:
- Literature review of pyroptosis mechanisms.
- Analysis of pyroptosis's role in tumor biology.
- Exploration of pyroptosis induction as a cancer therapy strategy.
Main Results:
- Pyroptosis has diverse cellular mechanisms and roles beyond infection defense.
- It is implicated in tumor initiation, progression, metastasis, and drug response.
- Pyroptosis induction is observed in various cancers like lung, colorectal, gastric, hepatocellular carcinoma, and melanoma.
Conclusions:
- Pyroptosis is a multifaceted cell death pathway with significant implications in cancer.
- Targeting pyroptosis offers a promising therapeutic avenue for various cancers.
- Further research into pyroptosis induction, particularly in melanoma, is warranted for clinical application.
