Leveraging aptamers for targeted protein degradation

Area of Science:

• Biochemistry
• Molecular Biology
• Drug Discovery

Background:

• Targeted protein degradation (TPD) is a revolutionary drug discovery approach.
• Proteolysis-targeting chimeras (PROTACs) are a key TPD technology facing challenges like ligand identification and toxicity.
• Undruggable proteins remain a significant therapeutic target.

Purpose of the Study:

• To review recent advancements in aptamer-based TPD.
• To highlight aptamers' potential in overcoming PROTAC limitations.
• To discuss the future clinical applications of aptamer-based TPD.

Main Methods:

• Literature review of aptamer-based TPD strategies.
• Analysis of aptamer properties for molecular recognition.
• Evaluation of TPD challenges and aptamer solutions.

Main Results:

• Aptamers demonstrate broad molecular recognition capabilities.
• Aptamer-based TPD shows potential for targeted delivery and spatiotemporal control.
• Aptamers can address challenges like poor solubility and off-tissue toxicity.

Conclusions:

• Aptamer-based TPD offers a promising alternative to traditional PROTACs.
• This approach could enable the degradation of previously undruggable proteins.
• Further research is needed to facilitate clinical translation.
