Fig. 7From: DUP1 peptide modified micelle efficiently targeted delivery paclitaxel and enhance mitochondrial apoptosis on PSMA-negative prostate cancer cellsThe in vitro cytotoxicity of the free PTX, Chol–mPEG–M-PTX, and Chol–PEG–DUP1–M-PTX on PC-3 cell lines (48 h). The percentage of viable cells was quantified using the methylthiazoletetrazolium method. Mean values and 95 % confidence intervals derived from three independent experiments are shown, *p < 0.05Back to article page
