Despite the considerable progress made in the field of anticancer nanomedicine, the influence of the physicochemical characteristics of the nanoconstructs on their internalization and cytotoxicity towards specific cancer cells remains to be fully understood. The aim of this in vitro study was to examine the factors influencing the potency of styrene maleic acid (SMA-Dox) micelles loaded with doxorubicin in a range of 4.4% to 28.4% using breast cancer and prostate cancer cell lines. A significant difference in cytotoxicity relative to micelle loading was observed and correlated with the expression level of caveolin-1. The expression level of caveolin-1 has previously been associated with advanced, aggressive cancer subtypes. For example, SMA-Dox micelles were shown to co-localize with caveolin-1 in PC3 cells and this colocalization was disrupted by treatment with the caveolin-1 inhibit.. View More»
