Aptamer-mediated cancer gene therapy

Area of Science:

• Biotechnology
• Molecular Biology
• Oncology

Background:

• Cancer is a leading global cause of death, often treated with conventional therapies like chemotherapy and radiotherapy, which have significant drawbacks.
• There is an urgent need for more effective cancer treatments with reduced side effects.

Purpose of the Study:

• To review recent advancements in aptamer-mediated gene therapy for hepatocellular carcinoma and other cancers.
• To highlight the potential of aptamer-guided gene therapy as a novel targeted cancer treatment.

Main Methods:

• Aptamers (single-stranded DNA or RNA molecules) are utilized for their high-affinity and specific binding to target molecules.
• Aptamers facilitate the targeted delivery of therapeutic nucleic acids (e.g., siRNA, miRNA) to cancer cells.
• Aptamers can also guide nanoparticles carrying therapeutic nucleic acids.

Main Results:

• Aptamer-guided gene therapy demonstrates potential in targeting cancer cells specifically.
• This approach enables direct delivery of anti-cancer nucleic acids or guides therapeutic nanoparticles.
• Recent progress shows promise for treating hepatocellular carcinoma and other cancers.

Conclusions:

• Aptamer-mediated gene therapy represents a significant advancement in targeted cancer treatment.
• This strategy offers a promising alternative to conventional cancer therapies with potentially fewer side effects.
• Further research into aptamer-guided gene therapy is warranted for its clinical application.
