Cancer therapy: Targeting mitochondria and other sub-cellular organelles

Area of Science:

• Oncology
• Cell Biology
• Molecular Biology

Background:

• Tumour cell death is essential for natural tumour suppression.
• Cancer cells evade cell death through deregulated pathways involving cellular organelles.
• While classical apoptosis is known, alternative and non-apoptotic pathways also contribute to tumour cell death.

Purpose of the Study:

• To review the role of cellular organelles in tumour initiation and progression.
• To explore alternative and non-apoptotic pathways in tumour cell death.
• To summarize current drug development targeting deregulated organelles in cancer.

Main Methods:

• Literature review of scientific publications.
• Analysis of data on tumour cell death mechanisms.
• Summary of current therapeutic strategies targeting cellular organelles.

Main Results:

• Deregulated organelles (mitochondria, ER, Golgi, lysosomes) are implicated in tumourigenesis.
• Alternative apoptotic and non-apoptotic pathways contribute to tumour cell death.
• Organelle dysregulations present druggable targets for cancer therapy.

Conclusions:

• Targeting specific organelle dysfunctions represents a promising avenue for rational cancer drug design.
• Understanding diverse cell death pathways enhances therapeutic intervention strategies.
• Further research into organelle-targeted therapies is warranted.
