Targeting Programmed Cell Death Using Small-Molecule Compounds to Improve Potential Cancer Therapy.

Area of Science:

• Molecular Biology
• Oncology
• Biochemistry

Background:

• Cancer cells exhibit evasion of cell death, a key hallmark.
• Understanding diverse cell death pathways is crucial for cancer pathogenesis and therapy.
• Classification of cell death has shifted from morphology to molecular definitions.

Purpose of the Study:

• To review 12 distinct cell death subroutines.
• To discuss small-molecule compounds targeting these subroutines for cancer therapy.
• To bridge the gap between cell death mechanisms and small-molecule drug development.

Main Methods:

• Comprehensive literature review of cell death subroutines.
• Analysis of molecular mechanisms for each cell death type.
• Identification of small-molecule compounds linked to specific cell death pathways.

Main Results:

• Detailed summary of 12 cell death subroutines including apoptosis, necroptosis, ferroptosis, and pyroptosis.
• Elucidation of molecular mechanisms underlying each cell death subroutine.
• Identification of emerging small-molecule compounds with therapeutic potential.

Conclusions:

• Diverse cell death pathways offer numerous targets for cancer therapy.
• Small-molecule compounds are vital for targeting both classical and novel cell death modalities.
• Further research into the relationships between cell death subroutines can refine cancer therapeutic strategies.
