Is the cancer stem cell population "a player" in multi-drug resistance?

Area of Science:

• Oncology
• Cancer Stem Cell Biology
• Molecular Targeted Therapy

Background:

• Cancer is increasingly viewed as a stem cell disease.
• This paradigm shift necessitates new therapeutic strategies targeting cancer stem cells.
• Integrating molecular targeted therapy with cancer stem cell concepts is a key research area.

Purpose of the Study:

• To review molecular targeted therapy strategies against cancer stem cells.
• To categorize these therapies based on their molecular targets.
• To highlight the potential of targeting cancer stem cells for improved cancer treatment.

Main Methods:

• Review of current research on cancer stem cells and molecular targeted therapy.
• Categorization of molecular targets for cancer stem cell therapy.
• Discussion of specific molecular targets including surface molecules, drug resistance proteins, oncoproteins, stem cell pathways, survival factors, and oxidative stress.

Main Results:

• Molecular targeted therapy against cancer stem cells can be classified into six categories.
• These categories include targeting surface molecules, ABC multidrug resistance proteins, specific oncoproteins, stem cell pathways, survival factors (e.g., NF-kappaB, PI3K), and oxidative stress.
• The review outlines the diverse molecular targets crucial for cancer stem cell survival and proliferation.

Conclusions:

• Targeting cancer stem cells represents a promising therapeutic avenue.
• Molecular targeted therapy offers a framework for developing novel anti-cancer stem cell strategies.
• Further research into these targeted therapies could revolutionize cancer treatment approaches.
