Aptamers: Novel Therapeutics and Potential Role in Neuro-Oncology

Area of Science:

• Biotechnology
• Oncology
• Molecular Biology

Background:

• Aptamers are emerging as a significant tool in cancer therapeutics, functioning as standalone agents or drug delivery vehicles.
• Despite decades of research and regulatory approval, aptamer translation into clinical oncology settings faces challenges.
• While aptamer applications in adult glioblastoma exist, their role in pediatric neuro-oncology remains largely unexplored.

Purpose of the Study:

• To review the fundamental biology of aptamers, focusing on their cell surface protein targeting mechanisms.
• To discuss structural modifications aimed at enhancing aptamer therapeutic efficacy.
• To examine the current status and challenges of aptamer utilization in neuro-oncology, with a specific focus on pediatric brain tumors.

Main Methods:

• Literature review of aptamer biology, targeting mechanisms, and modifications.
• Analysis of existing aptamer research in neuro-oncology, particularly glioblastoma.
• Exploration of translational challenges and future directions for aptamer applications.

Main Results:

• Aptamers demonstrate versatile therapeutic and diagnostic potential through specific cell surface protein interactions.
• Structural modifications can significantly improve aptamer stability and efficacy.
• Significant gaps exist in the translation of aptamer technology to pediatric neuro-oncology.

Conclusions:

• Aptamers hold considerable promise for targeted cancer therapy and drug delivery.
• Further research is needed to overcome translational hurdles and explore aptamer utility in pediatric brain tumors.
• This review highlights the untapped potential of aptamers in addressing a critical unmet need in pediatric oncology.
