Recent Advances in Cell Penetrating Peptide-Based Anticancer Therapies

Area of Science:

• Biochemistry and Molecular Biology
• Biotechnology
• Pharmacology

Background:

• Cell-penetrating peptides (CPPs) are amino-acid sequences capable of crossing cell membranes.
• CPPs facilitate intracellular delivery of diverse cargos like nucleic acids and proteins.
• Applications span cell imaging, gene editing, and therapeutic delivery since 1988.

Purpose of the Study:

• To review recent advances in CPP applications for cancer therapy.
• To highlight CPP-mediated delivery of anti-tumoral proteins.
• To discuss strategies for improving CPP specificity and efficacy.

Main Methods:

• Review of existing literature on CPPs in cancer therapy.
• Analysis of studies employing cell-specific CPPs or targeted cargo.
• Examination of CPP-cargo complex conjugation for enhanced specificity.

Main Results:

• CPPs offer rapid, potent delivery with lower toxicity than many drug carriers.
• Strategies involving cell-specific CPPs or targeted cargo show promising results.
• CPP-mediated delivery of anti-tumoral proteins is a key area of focus.

Conclusions:

• CPPs represent a valuable platform for targeted cancer therapy delivery.
• Overcoming CPP instability and lack of specificity is crucial for clinical translation.
• Further research into CPP-cargo complexes and targeted delivery holds significant therapeutic potential.
