Cell cytotoxicity and proapoptosis effect of KLA peptide and KLA-loaded HPMA copolymers. (A) Biocompatibility investigation of drug-free carrier HPMA copolymer and G3-C12-HPMA copolymer. (B) Viability of PC-3 cells treated with predetermined concentration of free KLA, HPMA-KLA and G3-C12-HPMA-KLA, respectively. (C) Apoptosis assay of PC-3 cells after treatments as indicated for 24 h at the equivalent KLA concentration of 25 nmol/mL.
