Cancer cells stemness: A doorstep to targeted therapy

Area of Science:

• Oncology
• Cancer Biology
• Stem Cell Research

Background:

• Despite advances in cancer research and drug development, tumor recurrence, metastasis, and therapy resistance remain significant challenges.
• Cancer stem cells (CSCs) are increasingly recognized as a critical factor in disease propagation, relapse, and treatment failure.
• CSCs exhibit self-renewal, differentiation, and proliferation capabilities, similar to normal stem cells, and possess inherent resistance to conventional therapies.

Purpose of the Study:

• To review the underlying molecular mechanisms and targets associated with cancer stem cell (CSC) properties.
• To explore CSCs as a key target for developing effective therapeutic strategies against cancer.
• To summarize potential CSC biomarkers and pathways for complete cancer treatment and overcoming chemoresistance.

Main Methods:

• This review synthesizes current scientific literature on cancer stem cells.
• It analyzes molecular targets including signaling pathways, cell surface markers, and microRNAs implicated in CSCs.
• The review discusses the role of the tumor microenvironment and apoptotic pathways in CSC maintenance and drug resistance.

Main Results:

• CSCs are responsible for tumor reconstitution, metastasis, and resistance to anticancer therapies, leading to relapse.
• The stemness properties of CSCs are regulated by a complex network of molecular targets.
• Targeting these specific CSC biomarkers presents a promising avenue for eradicating cancer stemness.

Conclusions:

• Targeting cancer stem cells (CSCs) is crucial for achieving complete cancer eradication and preventing disease recurrence.
• Inhibiting CSC-specific molecular targets offers a novel therapeutic strategy to overcome chemoresistance and improve patient outcomes.
• Further research into CSC biology and targeted therapies is essential for advancing cancer treatment.
