Tumor-Selective Cytotoxicity of Nitidine Results from Its Rapid Accumulation into Mitochondria

Figure 1

Fluorescent images of nitidine (NTD) and organelle-specific fluorescent proteins. A549 cells were transfected with each organelle-specific recombinant protein supplied in the Organelle Lights™ kit (red fluorescent protein (RFP)). The fluorescent images of NTD were observed under ultraviolet (UV) light (358 ± 28 nm).
