ICE/CED3-like proteases as therapeutic targets for the control of inappropriate apoptosis

Abstract:
Excessive or failed apoptosis is a prominent morphological feature of several human diseases. Many of the key biochemical players that contribute to the highly ordered process of apoptotic cell death have recently been identified. These include members of the emerging family of cysteine proteases related to mammalian interleukin-1 beta converting enzyme (ICE) and to CED-3, the product of a gene that is necessary for programmed cell death in the nematode C. elegans. Among a growing number of potential molecular targets for the control of human diseases where inappropriate apoptosis is prominent, ICE/CED-3-like proteases may be an attractive and tangible point for therapeutic intervention.
Insights
Dysregulated apoptosis, or programmed cell death, is implicated in human diseases. Targeting ICE/CED-3-like proteases offers a potential therapeutic strategy for these conditions.
Area of Science:
- Biochemistry
- Molecular Biology
- Cell Biology
Background:
- Apoptosis, or programmed cell death, is crucial for human health.
- Aberrant apoptosis is a hallmark of numerous human diseases.
- Key biochemical regulators of apoptosis are increasingly being identified.
Purpose of the Study:
- To highlight the role of ICE/CED-3-like proteases in apoptosis.
- To explore these proteases as potential therapeutic targets.
Main Methods:
- Review of recent biochemical and genetic studies on apoptosis.
- Identification and characterization of cysteine proteases involved in apoptosis.
Main Results:
- The interleukin-1 beta converting enzyme (ICE) and CED-3 proteases are key players in apoptosis.
- ICE/CED-3-like proteases represent a conserved mechanism for apoptotic cell death.
- These proteases are implicated in various human diseases with abnormal apoptosis.
Conclusions:
- ICE/CED-3-like proteases are critical mediators of apoptosis.
- Targeting these proteases presents a promising therapeutic avenue for diseases characterized by excessive or insufficient apoptosis.
