Aptamers: A Promising Tool to Combat Cancer

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Aptamers are short, single-stranded oligonucleotides with stable 3D structures.
• They exhibit high affinity and specificity for target molecules, outperforming antibodies in some applications.
• Aptamers offer advantages like thermal stability, ease of synthesis, and low toxicity.

Purpose of the Study:

• To review the diagnostic and therapeutic applications of aptamers in oncology.
• To discuss aptamer generation strategies for cancer therapy.
• To highlight aptamer advantages over traditional immunotherapies.

Main Methods:

• Literature review of aptamer applications in cancer research.
• Analysis of aptamer-based cancer diagnosis and biomarker discovery.
• Examination of aptamer-targeting strategies for cancer therapy.

Main Results:

• Aptamers demonstrate significant potential in cancer diagnosis and biomarker discovery.
• They can be engineered to target neoplastic cells directly or indirectly, inhibiting proliferation.
• Aptamers show promise as alternatives to antibody-based immunotherapies.

Conclusions:

• Aptamers represent a promising class of molecules for cancer therapy and diagnosis.
• Their unique properties offer advantages over conventional treatments.
• Ongoing clinical trials underscore their therapeutic potential.
