Neurotensin Branched Peptide as a Tumor-Targeting Agent for Human Bladder Cancer

Figure 2

Cytotoxicity of NT4 peptide conjugated with methotrexate (MTX), or gemcitabine (GEM) in T24 (a) and HT-1376 (b) cell lines. Cytotoxicity of drug-conjugated NT4 (NT4-GEM or NT4-MTX) was compared with that of the corresponding free drugs (GEM or MTX) and an unrelated tetrabranched peptide (U4-GEM or U4-MTX), identically conjugated to the same drug.
