Abstract
Polyphyllin II (PPII) has been proven to have significant anti-liver cancer activity, but its application is limited by poor solubility, low bioavailability, and systemic toxicity caused by non-selectivity. To address the above problem, PPII was encapsulated into the Poly (lactic-co-glycolic acid) (PLGA) by precipitation method (PPII-NPs) for hepatocellular carcinoma treatment. Subsequently, Box–Behnken design (BBD) with three variables-three levels (33) was utilized to optimize the PPII-NPs formulation. Under optimal conditions, the drug loading of nanoparticles reached 7.29 ± 0.08% and encapsulation efficiency was 80.98 ± 1.63%. Furthermore, aptamer AS1411 was adopted to enhance the tumor-targeting ability of nanoparticles (Apt/PPII-NPs). The drug loading of Apt/PPII-NPs was 6.25 ± 0.26%, had a spherical shape with a rough surface, a particle size of 252.3 ± 3.6 nm, and showed good slow-release performance and stability. In vitro, assays showed that the targeted modified nanoparticles had significant tumor selectivity and exerted efficient anti-tumor effects by inducing tumor cell apoptosis via the mitochondrial apoptotic pathway and death‐receptor pathway. In vivo, anti-tumor evaluation further demonstrated Apt/PPII-NPs not only effectively inhibited the growth of tumors, but also reduced PPII damage to normal tissues. In summary, this report strongly illustrated the advantages of a targeted nanoparticle platform for providing a solution for the rational application of PPII and improving the therapeutic effect of hepatocellular carcinoma.
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
