Viability of LNCaP cells in 3D spheroid cultures. (A) Docetaxel-encapsulated,
targeted polymersomes (purple bar) were more potent compared to the
free drug (orange bar), targeted vesicles without any drug (green
bar), nontargeted polymersomes without any drug (pink bar), and the
media (cyan bar). (B) Mocetinostat-encapsulated, targeted polymersomes
(purple bar) were more potent compared to the free drug (orange bar),
targeted vesicles without any drug (green bar), nontargeted polymersomes
without any drug (pink bar), and the media (cyan bar). (C) The combination
of docetaxel/mocetinostat-encapsulated targeted polymersomes (purple
bar) was more potent compared to the free drug (orange bar), targeted
vesicles without any drug (green bar), nontargeted polymersomes without
any drug (pink bar), and the media (cyan bar). Data presented are
representative of three individual experiments. Error bars denote
the mean ± SEM. Statistical analysis: Student’s t-test where *p < 0.05, **p < 0.001, and ***p < 0.0001.
