Abstract
Objective: To synthesise HSA-RB-DOX nanoparticles, measure its characteristics and preliminarily evaluate its anti-cancer effects.
Methods: Doxorubicin (DOX) and Rose Bengal (RB) were co-delivered using albumin as a carrier. HSA-RB-DOX nanoparticles were prepared by RB-induced self-assembly of albumin. Its characteristics were measured and anti-cancer effects were tested in MCF-7 cells and tumour-bearing mice.
Results: HSA-RB-DOX nanoparticle with a mean size of 42 nm was stable in different medium and behaved controlled release characteristic. It was well took in MCF-7 cells and inhibited MCF-7 cells proliferation by inducing reactive oxygen species (ROS) production. It retained a much higher blood concentration up to 12 h and accumulated more in tumour tissues. In tumour-bearing mice, HSA-RB-DOX nanoparticles inhibited tumour growth and even decreased its volume from 100 to 50 mm3, with barely no influence on body weight.
Conclusions: HSA-RB-DOX nanoparticles may be potentially used for enhanced treatment of breast cancer.
