Abstract:
Cytotoxic drugs have long been recognised to kill cancer cells through apoptosis. According to a current study, pyroptosis inhibits cell proliferation and shrinks tumors. Pyroptosis and apoptosis are caspase-dependent programmed cell death (PCD) processes. Inflammasomes activate caspase-1 and latent cytokines, including IL-1β and IL-18, to cleave gasdermin E (GSDME) and induce pyroptosis. Gasdermin proteins activate caspase-3 to induce pyroptosis, which is associated with tumour genesis, development, and therapy response. These proteins may serve as therapeutic biomarkers for cancer detection, and their antagonists may be a new target. Caspase-3, a crucial protein in both pyroptosis and apoptosis, governs tumour cytotoxicity when activated, and GSDME expression modulates this. Once active caspase-3 cleaves GSDME, its N-terminal domain punches holes in the cell membrane, causing it to expand, burst, and die. To understand the cellular and molecular mechanisms of PCD mediated by caspase-3 and GSDME, we focused on pyroptosis. Hence, caspase-3 and GSDME may be promising targets for cancer treatment.
Insights
Pyroptosis, a programmed cell death, inhibits cancer cell proliferation and tumor growth. Caspase-3 and gasdermin E (GSDME) are key regulators of pyroptosis and may be promising therapeutic targets for cancer treatment.
Area of Science:
- Cellular biology
- Molecular mechanisms of cell death
- Cancer research
Background:
- Cytotoxic drugs induce cancer cell death via apoptosis.
- Pyroptosis is another programmed cell death pathway that inhibits cell proliferation and shrinks tumors.
- Both pyroptosis and apoptosis are caspase-dependent processes.
Purpose of the Study:
- To investigate the role of pyroptosis in cancer.
- To understand the cellular and molecular mechanisms of caspase-3 and gasdermin E (GSDME) mediated programmed cell death.
- To explore caspase-3 and GSDME as potential therapeutic targets for cancer treatment.
Main Methods:
- Focus on pyroptosis mechanisms.
- Analysis of inflammasome activation, caspase-1, and cytokine cleavage (IL-1β, IL-18).
- Investigated gasdermin E (GSDME) cleavage and its role in pyroptosis.
Main Results:
- Pyroptosis inhibits cancer cell proliferation and tumor growth.
- Gasdermin proteins, including GSDME, are crucial for pyroptosis.
- Activated caspase-3 cleaves GSDME, leading to cell membrane pore formation and cell death.
Conclusions:
- Caspase-3 and GSDME are central to pyroptosis.
- These proteins are implicated in tumor genesis, development, and response to therapy.
- Caspase-3 and GSDME represent promising therapeutic targets for cancer treatment.
