The EpCAM aptamer conjugated Neocarzinostatin (NCS) shows specificity to EpCAM-positive cells. The effects of the conjugates on cancer cells are impressive as the conjugate arrests the cell cycle and promoted apoptosis and necrosis. The high levels of PARP expression confirmed the DNA breaks upon conjugate treatment. NCS conjugated with EpCAM can be targeted to cancer cells sparing normal cells.
The IC ₅₀ values of Neocarzinostatin (72 hours) to C6 cells and U87MG cells were 493.64 nM, 462.96 nM, respectively.
In human tumor cell lines of different tissue origins, sensitivity to neocarzinostatin is proportional to the product of the relative contents of Bcl-2 and caspase-3.
