Organic solvents have been reported to exert certain influence on the structure and drug loading efficiency of albumin. It is urgent to develop organic solvent-free albumin-based paclitaxel nanoparticles for effective anticancer therapy. In this study, novel PTX liposome-albumin composite nanoparticles (Lip-PTX/BSA NPs) aimed at avoiding the direct contact of albumin with toxic organic solvents and enhancing the colloidal stability of the formulation were prepared. To methodically evaluate the impacts of multifarious factors on the critical characteristics of the nanoparticles, Box-Behnken design was applied in the formulation optimized process. Ratio of drug-phosphatidylcholine (EPC), ratio of drug-BSA and pH of the media were chosen as the independent variables, while particle size and drug-loading content (DLC) loss rate were applied as the selected response variables. A quadratic model fitted best to describe the data with maximal lack-of-fit p-value and minimum sequential p-value. Three-dimension surface figures were utilized to describe the correlation of independent variables with response variables. Optimized formulation of the nanoparticles with size of 116.2 ± 2.0 nm and zeta potential of -18.4 ± 1.01 mV were obtained with a high encapsulation efficiency of 99.8%. PTX was involved physical interaction with the excipient during the preparation process of the nanoparticles. The release of PTX from Lip-PTX/BSA NPs exhibited a sustained release manner compared to albumin-bound PTX (nab-PTX) and Taxol. Besides, Lip-PTX/BSA NPs presented enhanced in vitro cytotoxicity against 4T1 cells due to highly nonspecific internalization in the cytoplasm. Simultaneously, Lip-PTX/BSA NPs showed effective in vivo antitumor efficacy against 4T1 bearing BALB/c mice, while no apparent adverse effect was observed by histological section and blood biochemical analysis. In conclusion, the novel Lip-PTX/BSA NPs could be applied as a promising drug delivery system for PTX to exert efficient cancer curative effects in clinic.

A condition in which albumin level in blood (SERUM ALBUMIN) is below the normal range. Hypoalbuminemia may be due to decreased hepatic albumin synthesis, increased albumin catabolism, altered albumin distribution, or albumin loss through the urine (ALBUMINURIA).
A chlorinated hydrocarbon that has been used as an inhalation anesthetic and acts as a narcotic in high concentrations. Its primary use is as a solvent in manufacturing and food technology.
Manufacturing technology for making microscopic devices in the micrometer range (typically 1-100 micrometers), such as integrated circuits or MEMS. The process usually involves replication and parallel fabrication of hundreds or millions of identical structures using various thin film deposition techniques and carried out in environmentally-controlled clean rooms.
An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
