Advances in Cancer Gene Therapy: Nanomaterial-Based Encapsulation Strategies for Enhanced Delivery and Efficacy of Curcumin

Researchers from Xi'an Jiaotong University have made significant progress in the field of cancer gene therapy, focusing on the use of nanomaterial-based encapsulation strategies to enhance the delivery and efficacy of curcumin, a polyphenolic compound with anti-inflammatory, antioxidant, and antitumor properties. Despite its therapeutic potential, curcumin's poor aqueous solubility, rapid metabolism, and limited bioavailability have hindered its clinical application. To address these limitations, various nanomaterial-based encapsulation strategies have been developed, including polymeric nanoparticles, liposomes, solid lipid nanoparticles, micelles, dendrimers, and hybrid nanomaterials.

The study's findings indicate that curcumin-loaded nanocarriers exhibit enhanced antitumor effects, selective cytotoxicity toward cancer cells, and minimized side effects. However, challenges such as achieving tissue specificity, evaluating potential toxicity, and the need for thorough clinical validation persist. The researchers emphasize the importance of future research to prioritize the development of tissue-specific delivery systems, assess safety profiles, and ensure biocompatibility to optimize curcumin's clinical efficacy.
