Abstract:
Necroptosis is a type of regulated cell death that is increasingly being recognized as a relevant pathway in different pathological conditions. Necroptosis can occur in response to multiple stimuli, is triggered by the activation of death receptors, and is regulated by receptor-interacting protein kinases 1 and 3 and mixed-lineage kinase domain-like, which form a regulatory complex called the necrosome. Accumulating evidence suggests that necroptosis plays a complex role in cancer, which is likely context-dependent and can vary among different types of neoplasms. Necroptosis serves as an alternative mode of programmed cell death overcoming apoptosis and, as a pro-inflammatory death type, it may inhibit tumor progression by releasing damage-associated molecular patterns to elicit robust cross-priming of anti-tumor CD8+ T cells. The development of therapeutic strategies triggering necroptosis shows great potential for anti-cancer therapy. In this review, we summarize the current knowledge on necroptosis and its role in liver biliary neoplasms, underlying the potential of targeting necroptosis components for cancer treatment.
Insights
Necroptosis, a programmed cell death pathway, plays a complex role in cancer. Targeting necroptosis offers promising therapeutic strategies for liver biliary neoplasms.
Area of Science:
- Cell Biology
- Immunology
- Oncology
Background:
- Necroptosis is a regulated cell death pathway implicated in various pathologies.
- It is triggered by death receptors and regulated by RIPK1/3 and MLKL, forming the necrosome.
- Necroptosis acts as an alternative to apoptosis and can promote anti-tumor immunity.
Purpose of the Study:
- To review the current understanding of necroptosis.
- To explore the role of necroptosis in liver biliary neoplasms.
- To highlight the therapeutic potential of targeting necroptosis in cancer treatment.
Main Methods:
- Literature review of necroptosis.
- Analysis of necroptosis's role in cancer, specifically liver biliary neoplasms.
- Discussion of therapeutic strategies targeting necroptosis.
Main Results:
- Necroptosis has a context-dependent role in cancer, potentially inhibiting tumor progression.
- It can overcome apoptosis resistance and elicit anti-tumor CD8+ T cell responses.
- Targeting necroptosis components shows promise for anti-cancer therapy.
Conclusions:
- Necroptosis is a significant pathway in liver biliary neoplasms.
- Modulating necroptosis presents a viable strategy for developing novel cancer treatments.
- Further research into necroptosis-targeting therapies is warranted.
