Human Growth Hormone Fragment 176-191 Peptide Enhances the Toxicity of Doxorubicin-Loaded Chitosan Nanoparticles Against MCF-7 Breast Cancer Cells.
HumanDrug design, development and therapy · 2022
Researchers found that combining a specific peptide with doxorubicin-loaded nanoparticles significantly improved the drug's effectiveness against breast cancer cells. This dual-loaded approach not only enhanced the targeting of cancer cells but also showed potential to reduce side effects on healthy tissues. The study suggests a promising strategy for more effective cancer treatment.
- The addition of the hGH fragment 176-191 peptide improved doxorubicin's binding to breast cancer receptors.
- Dual-loaded Chitosan nanoparticles demonstrated greater anti-proliferative activity against MCF-7 breast cancer cells compared to doxorubicin alone.
- This method may enhance the anticancer potency of doxorubicin while minimizing harmful effects on non-cancerous tissues.
