Lysosomes as a Target of Anticancer Therapy

Area of Science:

• Cell Biology
• Molecular Oncology

Background:

• Lysosomes are vital organelles involved in cellular degradation and homeostasis.
• They play key roles in autophagy and various cell death pathways, including lysosomal and apoptotic death.
• Lysosomal membrane permeability can lead to cytoplasmic release of hydrolases, inducing lysosomal-mediated cell death.

Purpose of the Study:

• To explore the potential of lysosomal-mediated cell death in anti-cancer therapy.
• To investigate compounds that induce lysosomal membrane permeability and cell death.
• To examine the role of lysosomes as a therapeutic target for cancer and other diseases.

Main Methods:

• Review of compounds known to damage lysosomal membranes (e.g., lysosomotropic agents, chemotherapeutics).
• Analysis of the interplay between autophagy, apoptosis, and lysosomal cell death pathways.
• Exploration of combination therapies involving lysosomotropic compounds and autophagy modulators.

Main Results:

• Various agents, including drugs and plant compounds, can induce lysosomal membrane permeability and subsequent cell death.
• Lysosomal-mediated death is a viable pathway for cancer cells resistant to apoptosis or chemotherapy.
• Combining lysosomotropic compounds with autophagy modulators presents a novel therapeutic approach.

Conclusions:

• Lysosomes represent a promising therapeutic target for various diseases, particularly cancer.
• Targeting lysosomal-mediated cell death could offer an alternative treatment strategy for chemoresistant cancers.
• Further understanding of autophagy and apoptosis regulation is key to developing effective anticancer therapies.
