Deubiquitinases in cell death and inflammation

Area of Science:

• Molecular Biology
• Cell Biology
• Biochemistry

Background:

• Programmed cell death, including apoptosis, pyroptosis, and necroptosis, is crucial for eliminating compromised cells.
• Ubiquitination, a key post-translational modification, regulates proteins involved in cell death.
• Deubiquitinases (DUBs) reverse ubiquitination, thereby influencing cellular processes.

Purpose of the Study:

• To review the roles of deubiquitinases (DUBs) in programmed cell death.
• To elucidate how DUBs modulate apoptosis, pyroptosis, and necroptosis.
• To provide a comprehensive overview of DUBs' functions in cell death regulation.

Main Methods:

• Literature review of studies on deubiquitinases and programmed cell death.
• Analysis of molecular mechanisms by which DUBs affect apoptosis, pyroptosis, and necroptosis.
• Synthesis of findings on DUBs' dual roles as suppressors or promoters of cell death.

Main Results:

• Identified specific DUBs that either inhibit or activate apoptosis.
• Detailed the involvement of DUBs in regulating pyroptosis and necroptosis.
• Highlighted the diverse functions of DUBs in controlling cell death signaling pathways.

Conclusions:

• Deubiquitinases play critical, context-dependent roles in programmed cell death.
• Understanding DUBs' functions is essential for deciphering cell death mechanisms.
• Targeting DUBs may offer therapeutic strategies for diseases involving aberrant cell death.
