Abstract:
Hearing loss-associated protein gasdermin E (GSDME), an effector of secondary necrosis, has been identified in a new pathway of programmed cell death (PCD). GSDME epigenetic silencing and mutations resulting in loss-of-function have been reported in cancer tissues. Additionally, GSDME upregulation inhibits tumor proliferation as well as colony forming ability, and reduces the incidence of lymphatic metastasis, demonstrating that GSDME may act as a tumor suppressor. Here, we have focused on the molecular mechanisms of GSDME-mediated PCD, and tried to reveal the crosstalk between this cell death pathway and apoptosis, autophagy, GSDMD-mediated pyroptosis. Moreover, we concluded the anti-cancer activity of GSDME include forming permeable membranes, and triggering anti-cancer immunity. Thus, GSDME was potential to be a novel target for cancer prevention and treatment.
Insights
Gasdermin E (GSDME) triggers a novel cell death pathway, acting as a tumor suppressor. Its anti-cancer effects include membrane permeabilization and immune activation, making GSDME a promising target for cancer therapy.
Area of Science:
- Molecular Biology
- Cell Biology
- Immunology
Background:
- Gasdermin E (GSDME) is implicated in programmed cell death (PCD) and secondary necrosis.
- GSDME dysfunction (epigenetic silencing, mutations) is observed in cancer tissues.
- GSDME acts as a tumor suppressor by inhibiting proliferation, colony formation, and metastasis.
Purpose of the Study:
- Investigate the molecular mechanisms of GSDME-mediated PCD.
- Explore the crosstalk between GSDME-PCD and other cell death pathways (apoptosis, autophagy, pyroptosis).
- Elucidate GSDME's anti-cancer activities and therapeutic potential.
Main Methods:
- Analysis of GSDME's role in programmed cell death pathways.
- Investigation of molecular interactions with apoptosis, autophagy, and pyroptosis.
- Assessment of GSDME's impact on tumor growth and metastasis in cancer models.
Main Results:
- GSDME mediates a distinct programmed cell death pathway.
- GSDME interacts with apoptosis, autophagy, and GSDMD-mediated pyroptosis.
- GSDME exhibits anti-cancer properties by forming permeable membranes and activating anti-cancer immunity.
Conclusions:
- GSDME is a key regulator of a novel PCD pathway with tumor-suppressive functions.
- Understanding GSDME's molecular mechanisms reveals its crosstalk with other cell death processes.
- GSDME holds significant potential as a novel therapeutic target for cancer prevention and treatment.
